‘T
here is currently little push for the recycling of waste clothing’. So states
a report entitled ‘Mapping of evidence on sustainable impacts that
occur in the life cycles of clothing’ published by the UK government last
December. On a slightly more positive note, it adds that ‘technologies are
being developed that target the recycling and reuse of clothing. Currently most reuse of
clothing is achieved by charity shops. The majority of clothing that is discarded is sent
to landfill sites’. Well, perhaps that’s not particularly positive, but at least it shows that this
issue is ‘on the radar’.
According to the above research, textiles make up approximately 3% of the
domestic waste stream in the UK. And, as more clothing is purchased worldwide as
a result of ever-cheaper prices and an increasing population, you have to wonder if
the issue of textile recycling is in danger of being overlooked?
In the UK, as part of its work on Sustainable Consumption and Production, the
government is developing ten product ‘road maps’ to reduce the environmental and
social impacts of a range of priority products across their entire life cycles. Clothing
is one of these products.
A decree promoting used textiles recycling is being developed in France.
According to the April issue of BIR’s (Bureau of International Recycling) newsletter:
‘The French authorities have recently indicated that the regulatory texts have been
accepted by the French State Council (Conseil d’Etat) and hence proposed for
signature before further publication in the official journal.’
And textiles were one of several waste streams identified in the recent vote by
the European Parliament’s Environment Committee on the revised Waste Framework
Directive, wherein the Committee pushed for separate collection of different waste
streams. The discussions also yielded recycling targets, which stipulate that EU
Member States will have to achieve recycling rates of 50% for household and similar
wastes by 2020, and 70% recycling rates for construction and demolition waste
by the same date. It is possible that targets will also be set for manufacturing and
industrial waste. (For more on this vote, see the news story on page 9.)
The examples above suggest that some action is taking place in the political
arena. We can only hope that this will continue, and that, in parallel, investment will
continue within industry for specialist technologies that process textiles.
The next issue of WMW is our annual review and directory issue featuring
overviews of and insights into the current state of the waste sector. In the meantime,
I hope you enjoy our current issue, particularly the collection and transport special.

ISWA comments
ISWA Managing Director Greg Vogt argues that the waste
management industry must concentrate on producing quality
by-products in order to increase the recycling and reuse of
municipal solid waste
T
he increased demand for gas and petroleum, food crops, fish and large sources of
vegetative matter mean that the global harvesting of carbon has in turn intensified. It
could be said that mankind is mining nearly everything except its waste piles. Discussions
held at a recent ISWA Beacon Conference on biological treatment of biowastes (Perugia,
May 2008) suggest it is simply a matter of time until the significant carbon stream
present in municipal solid waste is fully captured. In the meantime, the waste industry needs to
continue on the pathway to increased awareness and better optimized biowaste resources.
While on-site rural composting is an age-old practice that we have come to rely on, other
approaches are taking longer to develop and mature. For example, backyard composting remains
in its infancy and will require more encouragement and public outreach to take off on a global
scale. Large-scale anaerobic digestion, MBT, and windrow-type composting facilities have
demonstrated various challenges in their use – mainly with handling, separation, processing
and achieving quality end-products. With much of the product stream being returned to
landfill as cover material or to thermal treatment processes as fuel, one wonders how these

Optimization of waste carbon may require widespread regulatory drivers (including
that mankind is

of waste carbon products for soil improvements/crop enhancements, and more

to capture a greater portion of the carbon stream and put it to beneficial use. From

waste piles
necessary before the available carbon in the waste stream can be extracted in sufficient
quality and quantities to create the desired end products. Other details need to be ironed
out too, including measurement methods, diversion calculations, sequestration values and
determination of acceptable contamination thresholds.
Reported tonnages of biowaste products are rising as our industry gets to grips with the
contributing factors (by measuring, estimating or both). Because biowaste products generally
feed the recycling numerator, recycling rates again rise, slowly but surely. Of course, we know
that simply creating more biowaste products is not necessarily the answer. For example, while
an organic product is seen as a good thing, a poor-quality compost can throw the benefits of the
process into doubt. Encouragement comes in the form of the growing number of global facilities
and operating experience, and increased interest by the private sector to manage the waste streams
from collection and onward. This progress will almost certainly improve product quality, and with
improved quality the products will find a market

JAPANESE GOVERNMENT PLANS TO
REDUCE WASTE BY 60%
Japan will urge citizens to carry
their own chopsticks instead of
using disposable ones and go
shopping with their own bags
instead of using plastic ones, in a
bid to more than halve the waste
it produces.
Plans to promote a recycling
society have been approved,
according to Tsuyoshi Kawakami,
an official in charge of recycling at
the Environment Ministry. Japan
aims to reduce the total amount
of waste – produced by both
industries and individuals – by
60% of the year 2000 level to 25.3
million tons (23 million metric
tonnes) by 2015 under the plan
posted on the ministry’s website.
Shoppers in Japan normally
receive multiple plastic and paper
bags, while gifts are typically
wrapped in elaborate packaging.
Environmentalists have criticized
the wide use of disposable
wooden chopsticks in the country.
Elsewhere in Japan, Yokohama
City and Lawson, Inc., a leading
Japanese convenience store chain,
have signed a waste reduction
agreement for two years, 2007
and 2008. This is the first such
agreement reached between the
city and a chainstore.
Yokohama has been promoting
a programme to reduce the
city’s waste volume by 30%
compared to 2001 levels by
2010, the ‘Yokohama G30 Waste
Reduction Plan.’ Toward this goal,
the city concluded an agreement
for the period from fiscal 2002
to 2006, called the ‘Agreement
on Eco-Friendly Activities for
Reduction of Containers and
Packages’, with local supermarkets,
department stores and consumers’
co-operative stores to promote
packaging waste reduction.
In 2007, this agreement
was renamed the ‘G30 Waste
Reduction Eco-Partner Agreement’,
and the city is now pursuing the
co-operation of convenience
stores. Under the agreement,
retailers must avoid unnecessary
packaging and promote the
recycling of paper cartons or
food trays by collecting them in
their stores.
IRELAND SMASHES WEEE AND PACKAGING
WASTE TARGETS
Figures for 2007 show that last
year Ireland collected double
the 2008 EU target of used
electrical items. WEEE Ireland,
the national compliance scheme
for electrical recycling has
revealed that it has collected
over 100,000 old electrical items.
These items weigh 28,000
tons (28,449 metric tonnes),
which gives an average of 9 kg
of WEEE per person. The EU
target per person in Ireland
for the year 2008 is just 4kg.
This amount of WEEE is a 12%
increase on the 2006 figures
and is a sum equivalent to the
weight of 200 jumbo jets.
Another achievement in
Ireland has been revealed
by 2005 figures produced by
the Environmental Protection
Agency (EPA) which showed
that the packaging waste
recovery rate was 59.9%. This
exceeded Ireland’s 50% target
for the year and came very
close to the much higher 60%
target which has been set for
the year 2011.
THE ART OF
RECYCLING IN
SINGAPORE
With Singapore aiming for a 60%
recycling rate in 2012, citizens
are keen to up their game and
improve upon the environmental
efforts they have already made.
Last year, more than half of
Singapore’s total waste was
recycled – but there is still a
feeling that more can be done.
The CEO of the National
Environment Agency, Lee Yuen
Hee has said, ‘We are happy
that more people are recycling.
However, more can be done to
educate some people on the
proper way to use recycling bins.’
With this in mind the EPA has
embarked upon an initiative
called ‘The Art of Recycling’.
This project, taking place in the
youth park at Somerset Road, will
see Singapore’s young people
decorating recycling bins as they
see fit in order to spread the
message and educate people to
use them properly.
The event will raise awareness
of the issue at hand as well as
giving young people a creative
way to get involved and spread
the message in their own
communities.

JOINT STATEMENT FROM REPIC
AND ELECTROLINK
REPIC and Electrolink have reached
an agreement for the trading of
WEEE evidence. This will contribute
towards the smooth running of the
WEEE process in the UK.
In a joint statement Philip Morton
of REPIC and Barry Van Danzig
of Electrolink said, ‘We both look
forward to working closely with all
stakeholders to achieve a workable,
environmental solution that
maximizes the recycling and re-use
of WEEE in the UK.’
THENERGO LAUNCHES NEW MULTI-FUEL
BIO-ENERGY PROJECT IN MEER, BELGIUM
BOA SETS ITS SIGHTS ON THE
GERMAN MARKET
Dutch company BOA Recycling
Equipment B.V. has opened a new
base in Viersen, Germany from
which it will focus on developing in
the German market. Uwe Höch will
head up this new location.
BOA has expanded its business
in the recycling sector, providing
components and equipment for
recycling and waste processing
and offering effective solutions by
combining proven technologies.
Bio-oil from jatropha seeds will fuel diesel engines at the new project
Thenergo has announced the
launch of a new CHP project in
Meer, Hoogstraten in the North of
Belgium.
The project, known as Binergy
Meer, will generate between
6.5 and 25 MWe of renewable
electricity and similar amounts of
renewable heat. It will be built in
several phases due to the need to
modify the local grid to inject the
generated electricity.
Binergy Meer will represent
an initial investment of €28.5
million, rising to at least €50
million if 25 MWe capacity is
reached. It is fully permitted, with
construction expected to start in
September 2008. The plant should
be operational in 2009 with the
potential to deliver between
52,000 and 200,000 MWh of
electricity covering the needs of
15,000 to 55,000 households.
The first phase will consist of
a 4 MWe biogas plant that will
convert 150,000 tonnes per year
of biomass and organic waste
into electricity and heat. Next to
this 4 MWe plant the project will
have 2.5 MWe of diesel engines
fuelled by jatropha bio-oil. The
biogas plant is designed to accept
a wide variety of feedstock such
as pig and chicken manure, food
industry waste, verge cuttings
and other organic materials
recovered from a wide range
of sources. Leysen, Thenergo’s
waste to energy unit, is the
principal sourcing contributor to
this project.

COLLEC TI O N A ND TR AN S P O R T SP E C I A L t INTRODUCTION

elcome to the latest Collection and Transport Special. The first thing to note here is the change of timing – from the
beginning of the year as it was previously, to the middle. May/June is a far better time of year to judge how both
product trends and the operational aspects of our industry are unfolding. I hope you agree.
At the time of writing, several brands of equipment from mainstream manufacturers were in the process of
coming under one sort of ‘marketing agreement’, or another. While that’s not necessarily a bad thing from the potential purchaser’s
point of view, it can result in less customer choice, or with larger manufacturing groups undertaking less research and development,
rather than more. On the other hand, from a manufacturing viewpoint, the waste and recycling industry probably
has more independent competitive brands fighting for global market domination than the total market can
realistically support.
There’s a dilemma for everyone in the market for new equipment here – do you favour the larger,
multinational brands because, generally speaking, they’re the safe option? Or do you reward a still
small, but expanding manufacturer, keen to try out innovative new ideas, with your business?
As you will observe from our cover story on the Italian manufacturer Iride, it is often the
smaller manufacturers that are able to translate clever ideas into reality in a shorter timescale.
And as the increased costs of fuel and finance start to impact on the global community, putting
new ideas into action quickly becomes even more crucial, in that it can save energy, as well as
money. The tough part for the smaller players is convincing customers in more distant markets
that their after-sales service back-up can match that of the big boys.
Interestingly, as several major manufacturers merge, or reach marketing agreements, Iride is
keen to expand both its product range and the extent of its market – it’s going to be one to watch.
Low emissions vehicles – such as diesel–electric hybrids – are also very much on the manufacturers’
agendas, as evidenced by the new offering from Isuzu. Meanwhile, sweepers running on natural gas and with
filters to reduce dust emissions were on show at the recent IFAT 2008 exhibition, along with new technology for all aspects
of waste collection, recycling and street cleaning – see our report on page 18. And you can see more from IFAT by visiting our website
www.waste-management-world.com – click on waste management industry videos.
It’s now very much up to the operators of waste and cleansing vehicles to push the manufacturers forward. Whether solutions
to vehicle emissions, greater community involvement or dust emissions will come from large international groups or the smaller
manufacturers is hard to say at this stage.
But time is running out for the environment. So the innovators have it all to gain.

The ease with which organized gangs of criminals can
target, steal and dispose of construction machinery
looks set to impact heavily on users, as yet another byproduct of the ‘credit crunch’, caused by over-lending in
the US mortgage market.
At present, manufacturers of plant are not required
by law to fit immobilizers, or to conform to any
international standards. Neither is there any obligation
to enter machine identity on to an independent
database, or to implement any other form of anti-theft
system. And the criminals know that.
At the same time, some insurance companies
have been less than vigilant in checking the details of
claims in order to identify fraud – and often pay up
the full, or even an inflated value of a stolen machine,
without investigation.
According to Tim Purbrick, managing director of
The National Plant and Equipment Register (TER), an
independent organization based in the UK, but working
internationally, finance groups are now starting to ask
questions – especially those with an insurance interest.
He also says that the level of theft is at an all-time high.
The value of stolen plant machinery and other equipment
is now grossing over £1 million ($1.9 million) a week in
the UK alone. But this is not just a national issue. As Tim
Purbrick explains, TER inspectors are now working with
police and other agencies throughout the world.
Several recent case studies from TER files underline
the growing trend of ‘stealing to order’ in one country
Sims Recycling Solutions, part of
the Sims Group, has brought its
various European divisions under
one brand identity. At the same
time, the company has announced
the acquisition of United Recycling
Industries (URI) and electronics
recycling specialist, Noranda
Recycling Inc in the US.
Sims Group chief executive
Jeremy Sutcliffe commented, ‘These
two well established businesses
operate to the highest of standards
and fit perfectly with Sims’ global
Recycling Solutions business.’
Sims has grown rapidly in
Europe over the past six years and
entered the US e-scrap market in
2003. Talking of URI and Noranda,
Jeremy Sutcliffe says, ‘These
businesses offer a premier solution
for the B2B sector in North America
and the combination of client
service standards and technological
capability will provide further
growth opportunities.’
It is claimed that Sims is now

PLANT THEFT CRACKDOWN OVERDUE?
Buying or selling at auction can be a cost-effective
solution, but a check on the TER database will ensure
the machine is legitimate
for export to another. ‘We’ve recently tracked John
Deere machines from the UK and Europe to Australia,
while our undercover inspectors are now regularly
spotting machines stolen from one country, entered
for auction in another,’ he confirms. To help overcome
this, the TER database can be accessed by subscribers
to ensure that machines offered for sale are not stolen.
‘Making it harder for thieves to sell on stolen equipment
is currently one of the best ways to drive down theft,’
Tim Purbrick confirms.

Italian sweeper manufacturer
Dulevo has added a truckmounted vacuum sweeper to its
existing range of 200 Quattro and
5000-based mechanical sweepers
and more recently introduced
compact vacuum machines.
Marketed as the Dulevo 7000,
the new machine was formally
launched at the recent Samoter
construction plant and vehicle show at Verona. It is best suited to 15 to 18
tonnes gross weight chassis.
US manufacturer Elgin Sweeper has announced it is mounting truckmounted vacuum sweeper equipment on the Nissan Diesel UD3300 in a
move to cut nitrogen oxides (NOx) and CO2 emissions.
New regulations in the US require a reduction in NOx by 90% and CO2
by 50% – standards that are met by the Nissan chassis. ‘After a thorough
review, we have determined that we can build on the UD3300 chassis,’
explains Brian Giles, sweeper products manager at Elgin.
The UD3300 – already popular for truck-mounted sweepers in Australia –
features a 230 hp diesel engine, driving through an Allison RDS transmission
and Meritor two-speed rear axle. Elgin will market the completed vehicle
with a three-year warranty.
As part of its agreement with Elgin, Nissan UD truck dealers will be able
to undertake warranty work.

COLLECTION AND TRANSPORT SPECIAL t IFAT 2008
Held once every three years, the IFAT trade show is one of the most
important exhibitions covering refuse collection and disposal, street
cleansing and winter/infrastructure maintenance. The 2008 Munich
event was well worth the wait.
IFAT 2008
The triennial trade show attracts professionals from

W
aste, recycling and composting equipment,
together with machine-based solutions to help
improve standards of cleansing and infrastructure
maintenance, have never been such a hot topic.
And judging from conversations with visitors
and exhibitors alike in Munich, there is a feeling of excitement
and a confidence that communities will increasingly demand that
their streets and highways are kept clean and tidy.
The majority of professionals seem to accept that in order
to increase levels of waste recycling further – and keep pace
with rising consumption of consumer goods exacerbated by the
still-growing global population – the size of the market for the
equipment we use must also grow significantly.
Domestically many European companies are forging ahead
with new ideas amid growing global competition. The leading
manufacturers are seeking to develop complex new products
in order to meet forthcoming EU legislation, while keeping
costs and prices low enough to prevent their home markets
being swamped by cheap foreign imports assembled by cheaper
labour. But while some manufacturers see that as a negative
and are getting entwined in increasingly confusing marketing
agreements with other brands, other leading companies have
managed to raise their game and have either maintained market
share in a toughening market, or managed to increase production
dramatically as a result of technical innovation.
Sweeper surge?
There has already been a significant number of new sweeper
models from the likes of Mathieu Yno, Johnston and Applied
– now it’s the turn of Scarab, Faun and Italian manufacturer

Dulevo. But while many manufacturers’ R&D departments have
been busily engaged in developing touch-screen controls, better
drive comfort and CANbus controls, the key issues seem to have
changed.
Actual load capacity is no longer the key operational
requirement, with both Dulevo and Ravo now offering Erdgas
(natural gas-fuelled) purpose-built skid sweepers in the 3–4 m3
class. The move – or should that be return – to natural gas for
powering municipal vehicles was perhaps one of the strongest
trends at IFAT this year. And if we had to give a prize to a single
machine that attempts to provide solutions to a host of waste
management issues, then the single truck-mounted sweeper on
the Faun stand had to take that prize. The 6 m3-capacity machine
was noteworthy first of all for being fitted with a dust filter pack
and a NOx particulates filter in the exhaust system. To help
reduce dust and increase efficiency, it uses the already available
Faun Viatec air recirculating system.
In addition, the standard hopper and sweep systems are
mounted on a shortened wheelbase Mercedes Benz Econic
chassis to give a low-entry facility for the driver and crew
members. Just to add to the impressive specification, this Faun
flagship includes hydrostatic drive, featuring a single engine
format. Faun also used IFAT to unveil its new Viajet-4 4 m3
machine, which features a hydrostatic transmission and single
engine and will be offered either as a vacuum machine, or as
a mechanical sweeper. As the actual pick-up system is different,
this will enable city authorities to undertake direct trials to
find out which system is best for any given application. It
might not sound that exciting, but in practical terms, it puts
Faun at the very heart of the dust emissions reduction debate.
And with Dulevo now also offering a vacuum truck-mount
as well as mechanical units (with some new models to come
shortly) the other manufacturers may well need to re-examine
their plans.
Waste collection
The most obvious headline in the world of waste collection and
disposal is one of consolidation and/or marketing co-operation
between brands that were formerly in competition with each
other. This has already dramatically reduced the number of
options available to the specifier in the context of truck chassis
choice – but it remains to be seen if the same will also occur in
the context of bodywork and handling equipment.
Waste Management World predicted this trend, but concluded
that it was likely that new, growing manufacturers would step in
to provide an added dimension of diversity and innovation. There
were twenty or more Italian suppliers at IFAT hoping to add
new customers from outside of the domestic market, along with
Czech-Republic based Kobit.
Recent dramatic growth means that Kobit is now exporting
a growing percentage of its products. The company was initially
a distributor for products designed and manufactured by others,
but today has its own design operation and is looking to produce
equipment to meet the needs of other markets – the co-operation
with Ausa, a leading manufacturer of dumpers, is a good example
of this trend.
Unfortunately, perhaps the most significant new product of
the past 12 months was not actually at IFAT ‘in the metal’ – and
you had to look very hard to find any evidence of its existence.
This is the recently designed ‘multi-modal’ waste collection
body transfer system developed for the City of London in the
UK, the production of which has been delayed by a combination
of political issues and more recently put on hold as a result of
a marketing deal by the Spanish RosRoca Group and Germanbased HN Logistic. Hopefully, the Scoutline multi-modal
system will survive – because it deserves to.
Disposal developments
Top of the list here has to be an added interest in smaller trucks
on the one hand and larger trucks on the other! To explain, waste
collection and recycling vehicles – and new designs of dedicated
food-waste collection units – seem to be downsizing in order to
be able to move more freely in congested city traffic, and get
over increasing restrictions on weight and width of vehicles in an
urban environment. The recent interest in satellite vehicles – still
a hot issue at IFAT – underlines this.
At the other end of the scale, a number of manufacturers
are looking to help bulk waste disposal and recycling operators
meet growing demand, by building innovative new products
such as hooklift demount semi-trailers as an alternative to the
drawbar trailers used in many markets. A lower chassis profile
and use of now readily available rear-steering trailer axles
all help to make for a unit that can carry more, with greater
utilization.
And let’s not forget the continuing interest in compact and
easily transportable crushers, screens, green-waste shredders
and other kit … Suffice it to say, IFAT provided enough feature
article ideas to last until ... Well, the next IFAT, which takes place
once again in Munich, Germany, between 9 and 13 May, 2011.

There is another environmental element, too. Being based
almost entirely on lighter-weight truck chassis, there are various
options available for either fully automatic or ‘clutchless’ gearshift
systems and hybrid/dual-fuel chassis specification options, while
for hilly districts – or where snow and ice are a problem in winter
– four-wheel drive options. All these things tend to be far easier
to specify on a chassis in the 3.5 to 10-tonne weight classes than
on chassis of 19 tonnes gross weight or more.
More congestion equals higher costs
But there’s one element of the story that has changed in the
past few years – the busy, prosperous parts of our world have
continued to get more and more congested with traffic. The mix
of high taxes and traffic congestion is increasingly unpleasant for
ordinary people, but for the politicians, it’s something of a tax
bonus – making them perhaps less keen to solve the problems.
Why is this? The answer is, vehicles stuck in traffic jams
continue to burn highly taxed fuel while going nowhere – which
gives politicians the excuse to introduce ‘congestion charge’
tolls which help bring in more tax revenue! This makes it
more expensive to run big trucks in general so it impacts on
waste collection vehicles. And while, on paper, big trucks are
more efficient than small ones, in practice, bigger trucks pay a
disproportionately higher amount of tax – and need bigger gaps
in traffic.
While distribution trucks bringing food, consumer goods
and new materials into urban areas can overcome congestion
by delivering at night, few residents would be happy with nighttime waste and recycled materials collections, due to the noise
and disruption this would cause. This means one of the most
important trucks caught up in rush hour traffic is increasingly
the urban refuse collection vehicle.
Attracting rental interest
So the question is: might it be possible to cut out the delays
by utilizing a larger ‘mother ship’ RCV with a number of
smaller satellite units in congested urban areas? Certainly, Iride
directors Franco Arduino and his brother Antonio think so. Their
company already has a good track record of meeting the needs
of customers from within Italy over a 25-year period, but more
recently, the decision was taken to increase the rate of production
– and the scope of the model range – to meet the demands of
customers outside Italy.
Iride products have, in fact, already been sold into other
Mediterranean markets such as Spain, Portugal, the south of
France and North Africa, but late in 2007, Iride announced it
would market its products for the first time in the UK as part of
a long-term plan to expand into the major northern European
markets and Scandinavia. In less than six months, EcoFar
UK (the newly-formed UK importer), has sold a number of
satellite units into both waste collection and recycled materials
applications, with considerable interest coming from the vehicle
rental sector.
Why might this be? One of the key advantages of the satellite
unit format – aside from it’s low price and high payload – is
that this type of vehicle is entirely leachate leak-proof. It can
therefore collect all types of waste material without leaving
unpleasant stains or residue on the highway. And while such
units soon become fully laden – when loaded with packaging
materials for example – there are operators who have found
them ideal for recycled materials collections, or implementing
dedicated food waste collections. Iride has recognized this fact
and introduced a split hopper design on its Eco Sat and Eco Side
Twin ranges. These allow for the collection of two waste streams
on one vehicle.
Iride has produced a high capacity 44-tonne gross weight articulated semi-trailer RCV for ‘mother ship’ operations working in conjunction with

But even more innovative options have recently been
designed. The elements of both ranges – rear-end loading and
side loading – can be combined onto a longer wheelbase 7.5 to
13-tonne gross weight chassis to give a three-compartment unit.
This would feature twin rear-loading compartments and a third
side-loading compartment, thus enabling three different waste
streams to be collected – all by hydraulic bin lifter. And the
significance of this is the price.
Such a unit would be less than half the cost of a typical fullsized recycling unit, if not a third. Can three smaller vehicles
work more efficiently than one large one? Not in every case,
no – as three drivers need to be employed instead of one – but
when actual loading times are measured against the time stuck
in traffic jams, smaller units might win the overall ‘carbon
footprint’ reduction race by achieving higher utilization as a
result of greater flexibility.

Mounting a challenge
Of course any new idea will have its detractors, and in the case
of satellite units, it might come as no surprise to learn that the
manufacturers of larger compaction-type RCVs are unlikely
to be happy to see their traditional markets invaded by more
compact satellite units. Although some manufacturers of larger
compaction types also market satellite units of their own design
– or already have marketing agreements with others – Iride is
out to challenge the established market leaders by introducing a
complementary range of compaction-type units as well.
All satellite units tend to feature a simple hydraulic packer
plate, which clears the rear of the hopper and provides some
measure of load security when laden, but the Iride product
range also includes the Eco-Compact design. This features a
clever cam-action compaction plate providing a higher degree of
compaction and ‘sweep’. From this design, it was a logical step to
a full-on compaction-type refuse collection vehicle and although
Iride holds the regional distributorship of the Mazzochia range of
compaction RCVs in part of Italy, Iride will launch a brand new
model of its own design next month, following the enlargement
of its product design office.
Known as Project Diechi (Project Ten) within the works,
this is a combined body/hopper compaction machine (making it
leachate leak-proof) using a two-stage rear-mounted packer plate
to clear the loading hopper area. The unit has been designed to

take a combined domestic/trade waste low-level bin lifter of Iride
design and construction, but the unit can also be loaded manually
if required by lowering the spill-tray.
When full, the load is discharged by ejector plate – just like
a conventional compaction-type RCV. But because there is no
‘split’ between body and hopper, Project Ten is designed so the
ejector plate forces the load out through the loading hopper.
To do this, the ejector plate has a drop-down ‘flipper’ section
to sweep the hopper as it passes. Project Ten will be available
initially in a 10 m3 body size, suitable for chassis in the 12 to 15tonne gross weight class. Based on early trials with the prototype
– which were being undertaken when Waste Management World
visited the Iride plant – a payload of 3–4 tonnes should be
possible. The newly announced model name for this product
will be EcoTen.
A bigger mother?
So when does an RCV cease to become a satellite unit? And does
it follow that all compact designs can be used in conjunction with
a larger mother ship vehicle? Vehicle size is an issue, but this is
primarily in respect of how much load the mother ship RCV’s
hopper can ‘digest’ in one go. At present, a rough guide would
suggest that any satellite unit with a capacity up to around 5 m3 of
household waste and up to 7 m3 of less-dense recycled materials
shouldn’t present a problem. But no, not all compact units are
suitable as ‘satellites’.
The key factor is not only to match the load discharge rate to
the compaction rate of the mother ship – to achieve the transfer
process, the satellite unit needs a high-tip capability. Getting the
geometry right is not as simple as it looks – especially as the bin
lifter must fold under the tipping body without fouling either
vehicle. Iride – and most other manufacturers – now provide
a CCTV camera system to ensure accurate ‘docking’. But now
Iride looks set to go even further and offer its own ideas in
mother ship design as well, giving this innovative manufacturer

the opportunity to market a complete waste collection system for
the first time.
Although articulated trucks are widely used in waste transfer
and bulk materials haulage, the use of articulated refuse collection
vehicles is far less common. The idea is not new however – major
cities such as London had articulated RCVs to negotiate narrow
streets back in the 1930s, while Hong Kong utilized compactiontype articulated trailers in the 1980s. Compaction trailers were left
at apartment blocks until full, with the tractor unit bringing in an
empty trailer and carting the full unit away. But could articulation
help boost the utilization issues we were looking at earlier?
Designers at Iride suggest some fresh thinking is long overdue
and having recently completed some large 44-tonne gross weight
articulated RCVs for a North African customer, have started
evaluating the concept of an articulated mother ship unit working
in conjunction with several satellite units on a linear collection
route. This method could have added benefits in the collection of
recycled materials as the greater capacity of an articulated trailer
(over a typical rigid truck-based mother ship) could enable it to
work an entire shift without having to unload.
Equally, such a unit could be ideal for trade or market waste
in that it could load builders’ skips up to 5 m3 capacity with
ease – yet be just as manoeuvrable as a three or four axle rigid
machine in traffic. The articulated mother ship trailer – branded
EcoMaxi by Iride – also enables a standard, higher-geared tractor
unit to be used when transferring laden trailers, with the option
that more specialized tractors with automatic transmission and
perhaps a low-entry crew cab might be used on the collection
operations in urban areas.
Whether this idea takes off, or not, one thing is for sure – with
its satellite vehicle range, Iride is already aiming high!

The Isuzu N62-150 Hybrid truck uses a 150hp diesel engine, supplemented by a battery pack/electric drive motor feeding into the existing truck
gearbox via the PTO outlet
municipal waste collection vehicles in Gothenburg, Sweden,
which recognize that the most harmful scenario relating to
exhaust emissions is when a conventional diesel truck is stuck
in stationary traffic, with the driver impatiently revving the
engine, waiting for the traffic to move off again. Isuzu engineers
have been able to overcome this waste of fuel and source of
drive-train wear by a combination of two components. The first
is the already well-proven electronic shift technology fitted to
an otherwise standard manual gearbox. This is given different
marketing names in different world markets, but in Englishspeaking markets, Isuzu calls it EasyShift and it’s already a
standard option on most conventional diesel Isuzus up to
13 tonnes gross weight.
The second element is an automatic engine cut-off and
restart system. Again, passenger cars have been fitted with such
a system to reduce emissions in stationary traffic, while the
garbage trucks used by Gothenburg City Council have taken the
idea a stage further, by utilizing battery packs to enable the bin
lifter and packing hydraulics to function while the diesel engine
is switched off during a stationary ‘work mode’ as well as in
stop/start traffic. So why hasn’t Isuzu gone for an electric-only
mode to enable the truck to be driven in stop/start traffic, or at a
reduced speed by purely electric motor drive?
The answer is, I’m told, that while it is technically possible,
Isuzu engineers were conscious of the need for any hybrid
technology truck to retain as useful a payload as any normal
diesel truck chassis. Incorporating a battery-electric only drive
mode would require a much larger – and heavier – battery pack,
which in turn would cost significantly more money to produce.
In other words, it’s a question of balance.

The chassis layout utilizes the existing truck drive train with the electric drive
motor mounted within the frame on the left side. The battery pack is mounted on
the outside of the left side chassis rail
My mission then, was to see if Isuzu engineers had got that
balance right. Working on the assumption that most trucks used
for waste and recycled materials collections, or other kinds
of urban cleansing and street maintenance operations, would
probably be expected to travel a considerable distance to and
from the work site at normal highway speeds, any hybrid has to
be at least as drivable as a conventional diesel truck – without
losing a significant percentage of payload capacity.
Looking for wider markets
In the case of the Isuzu N62-150 Hybrid, Japanese operating
conditions have dictated that the base chassis used is a 6.2-tonne
gross weight model. This has now been Type Approved for use
Artist’s impression shows how the hybrid components fit into existing diesel truck
chassis layout
in wider markets outside Japan. A look over the chassis layout
soon reinforces the view that packaging all the extra components
needed for the hybrid system into a small compact truck is
not an easy task. That Isuzu engineers have done so to a full
production standard – within a weight penalty of just 200 kg – is
one of the factors that makes this a landmark vehicle, provided,
that is, that the end result drives as well as a conventional dieselengined truck.
Given unhindered access to a laden production N62-150
Hybrid model and the use of an automotive industry test track
able to replicate all types of road conditions, my mission was to
see if the technology could be caught out by unusual conditions,
unsympathetic driving, or even outright driver abuse. Loaded to
full maximum gross weight, the Hybrid was repeatedly stopped,

all combined to minimize any damaging side-effects, while
actually making the driver’s job easier.
Clever technology
What sort of applications? This Novarini satellite unit is mounted on a dieselfuelled Isuzu chassis, but would work equally well on the N62-150 Hybrid
started, driven on full throttle and driven both up and down far
steeper hills than are likely to be found in any urban environment
outside of San Francisco.
With a conventional truck drive train comprising of clutch
and manual transmission, it would have been a matter of minutes
before the brakes and clutch would have been fried and, chances
are, the propshaft and the rest of the drive train damaged. Such
harsh use could have created transmission oil overheating on a
fully automatic transmission – and the normal service brakes
would certainly have suffered. With the Hybrid, the combination
of automatically activated electric motor ‘boost’ from standstill,
the cushioning effect of the EasyShift transmission and the
security of the regenerative braking system on downward slopes
So how’s it done? The answer is through clever electronics.
CANbus technology enables all the truck’s systems to ‘talk’ to
each other. I already knew from previous experience that the
electronically-activated EasyShift manual gearbox used on Isuzu
trucks was ideal for urban environments, without incurring the
power loss of fully automatic gearbox options. But what I hadn’t
bargained for was the significant advantages in having that large
electric motor to supplement the power from the 150hp diesel
engine. Isuzu couples the electric motor input shaft into the
gearbox by utilizing the existing PTO-mounting (power takeoff mounting). A short secondary propshaft provides the ‘drive’
function from the motor into the gearbox when acceleration is
required, but the energy is also passed back into the battery pack
when braking.
The electric motor is mounted within the chassis rails,
alongside the diesel engine drive train, while the battery pack is
located on the left side of the chassis, within the wheelbase. As
all the hybrid functions are ‘intelligent’ and automatic, there is no
need for complex controls in the driver’s cab. The performance
boost is significant, seamless and reduces the fuel consumption
of the diesel engine, while there is no need for the hybrid to be
treated in any special way.
Selecting a suitable application
So what can the N62-150 Hybrid be used for? And how much
extra, over the price of a comparable diesel Isuzu, does it cost?

RIGHT: It’s not quite San Francisco, but equally steep downhill slopes were used to
test the effectiveness of the regenerative braking system – and the ability of the

The fact that the hybrid drive uses the existing PTO output
mounting on the gearbox does suggest that any operations
requiring hydraulic power are compromised – which, of course,
when applied to waste and recycling operations is most of them!
But these are early days. The Italian manufacturer, Iride, is able
to adapt its engine pulley-driven PTO pump to suit the Isuzu
Hybrid layout. It could also be the case that an electro-hydraulic
capability could be provided using the hybrid drive electric
motor, while it might be possible to engineer a mirror image PTO
output position on the other side of the gearbox in the longer
term – although this isn’t possible at present. A fully electric
binlifter such as those produced by Ecoprocess in Iceland would
be ideally suited.
And price? This is often where the promise of new
environmentally friendly technology evaporates, but in the case
of the N62-150 Hybrid, the price differential looks set to be
‘around 7000 Euros ($11,000) over and above the price of a
standard diesel chassis’– which, coupled with a long-term leasing
arrangement on the battery pack, should at least enable hybrid
trucks to be operated to a pre-determined budget.
What sort of applications would suit hybrid technology
best? The obvious application is for satellite vehicles engaged on
domestic and light business waste or recycled materials collections
in heavily congested or environmentally sensitive areas. With a
lower cost and lower unladen weight advantage (compared
to small compaction-type units), the 200 kg Hybrid weight
penalty is not an issue. Equally, maintenance and traffic
management units sound like another natural application.
Isuzu is already one of the largest manufacturers of trucks
and diesel engines for other applications. Developing a hybrid
truck – and then putting it into production – is an indication that
this technology is here to stay.

You can walk it
Most operators are aware of ‘walking’, or moving
floor trailers for the efficient transport of waste
and recycled materials in bulk, but the same
basic principle can also be used to unload a
conventional trailer, or create a more mechanized
unloading pattern with moving floor trailers.
By using one or more Hallco Live Floors
systems, operators of waste and recycling vehicles
can speed up operations at landfill sites, transfer
stations or materials recovery facilities (MRFs)
– without increasing the numbers of wheeled
loaders and staff – and can, at the same time,
ensure safety isn’t compromised.
One or more Live Floors units can be installed
in just about any waste or recycling facility to
enable vehicles to ‘self unload’ in complete safety,
without having to wait in line. On landfill sites, the
use of Live Floors units allows more vehicles to
unload safely, as the design of these units ensures
that road-going vehicles don’t have to discharge
their loads directly at the landfill tip face.
Hallco Live Floors units are strong enough to
stand the strain of working with waste materials
and can be custom made to suit specific
applications. The units can be top loaded by
loading shovels if necessary and can be hitched
up to bailers or static compactors. Easy-to-install
snap-on slats reduce downtime in the event of
damage, while single unit construction ensures
quick and easy installation on site. A wide choice
of drive options is available and all hydraulic
circuits are factory pre-tested at full operational
pressures to ensure the units can be put straight
to work.

Containerize to optimize
Ground-level demountable container systems
offer one of the most efficient solutions to the
collection, transportation and disposal of waste
and recycled materials. In recent years it has
become increasingly important that the mounting
of hooklift and skiploader equipment takes into
account developments to truck chassis – and the
need to get optimum payloads within national
legal axle and gross weight limits.
To achieve that balance and still manufacture
equipment that can work reliably in the tough
waste and recycled materials environment
is no mean feat. Netherlands-based VDL
Containersystemen has continued to make
technical improvements to its product range and
early this year, introduced a new ‘CAN-control’
system with a new 130:1 control valve – giving
greater control precision with much-reduced fuel
costs as high truck engine revs are no longer
required to operate the hooklift system.
Another production improvement with
considerable long-term operator benefit is that
the latest VDL hooklift equipment is now available
completely finished, powder-coated and ready for
work. This saves the need to paint, or repaint units
after chassis installation. This new production
system ensures that a new hooklift unit can be
supplied, mounted and ready for work within
three days, claims the manufacturer.
VDL Containersystemen also markets a range
of skiptrucks – including a unit specifically designed
for the latest generations of 13–14-tonne gross
4x2 truck chassis that seem to be finding favour
in urban operations where width and weight
restrictions can cause expensive detours to larger
units. The VDL skiptruck range comes complete
with integrated container cover system, not only
to meet EU legal requirements, but also to ensure
that loss of material from the container when
travelling is all but eliminated.
After some eight years in the industry,
VDL Containersystemen now has units at work
internationally, with the ability to make special
options to suit individual markets; for example
in Switzerland and Scandinavia where low
temperatures are an issue, or in the UK where
controls need to be repositioned to fit with righthand steering applications. Special heavy duty
50-tonne capacity units for landfill, or heavy scrap
applications are also available.

principle, which has low life-cycle operating costs
due to the small number of moving parts. Sideloaders can be specified on either two- or threeaxle truck chassis and come in capacities of 14–24

In addition to this range of two-compartment

systems, now has a product range capable of
handling load capacities from 4 to 35 m3. NTM has
designed and built a ‘single lift’ system capable of
loading four independent waste streams at the
rear of the vehicle with its Quattro system.
The model range starts with the compact
K-2K and higher capacity KG-2K models, which
enable two waste streams to be collected from
hard-to-reach areas. The split-tailgate of the KG-2K
enables the collection of bins up to 660 litres on
the largest ‘slit’, with 370-litre bins on the smaller
side. The K-2K is designed for 7–10-tonne gross
weight chassis, while the larger KG-2K is designed
for two axle chassis up to 18 tonnes and three axle
chassis up to 26 tonnes gross weight.
For collection applications where the crosscontamination of waste streams is undesirable
– for example with food waste – NTM offers
the KGLS-2B/KG-2B models with two completely
separate bodies and tailgates, thus making crosscontamination impossible. These units are available
to fit 26-tonnes gross weight truck chassis.
The collection of organic – or ‘green’ – waste
can present major problems as leachate discharge
and other issues can present a challenge both to
reliability and legality of units in operation. NTM
offers a purpose-designed unit – the KGBH-2K
which is designed with higher side-walls to help
prevent spillage. Containers of 660 litres on the
largest ‘split’ and 370 on the smallest split can be
accommodated, although an option enabling
660-litre bins on both sides is also available.
In many markets, the use of one or two
man side-loading units can be ideal as a way
of reducing costs, or speeding up collections.

WASTE
management world
A new generation of underground waste
collection/storage system has been introduced by
German-based Bauer GmbH. Marketed as Model
GTR, the new system joins an existing range of
above ground, semi-underground and completely
underground products produced by this specialist
manufacturer. Although the GTR is still in what
the company considers to be phase one of its
introduction, it has already attracted orders thanks
to meeting all the demands of increased economy
and environmental standards.
All that is visible above ground is a simple
column and anti-slip pavement ‘plateau’. The new
system has been designed from the outset to
be readily accessible by children and wheelchair
users. The entire collecting chamber is located
below the surface, keeping odours at a minimum.
An important safety feature is that while
the galvanized metal inner container is raised
for emptying, a patented, self-closing platform
guarantees the safety of operatives or any passing
member of the public.
The GTR has been designed to provide city
authorities with the potential to install a highcapacity waste system that offers greater economies
of scale – in that it requires less-frequent collection
– without affecting the appearance of city centre
areas where hygiene and an attractive appearance
are essential. Putting waste material underground
has the added advantage of keeping the waste
cool in hot weather, thus reducing odours, and dry
in wet weather.
Weighing up the issues
As the waste industry develops from one where
disposal costs money to a position where recycled
waste materials actually have a market value, it’s
essential that the amount and weight of each
fraction is known throughout the whole process.
Clearly, overweight trucks can attract legal
penalties, but at the same time, the higher costs
of fuel and even mileage toll charges by national
governments, or city authorities, point to the
need for all waste and recycled materials trucks
to be loaded to the optimum payload figure –
without being over legal limits.
PM On-Board – now known as Vishay PM
Onboard – has been supplying accredited
weighing systems for over 22 years and has
been producing waste container weighing and
billing ID systems since 1999. The company is
BSI registered and is accredited by UK National
Weights and Measures.
Vishay PM Onboard’s BinWeigh system can

and compacted materials, as well as difficult
materials such as glass cullet, tyre crumb and
refuse-derived fuel (RDF). The savings and
efficiency gains to be made from a well-designed
and custom-built internal ‘static’ waste transfer
facility are of increasing importance as recycling
percentages increase and the costs of keeping
trucks waiting for a wheeled loader or telehandler
continue to rise. HydraTech specializes in such
applications, with all units supplied complete with
hydraulic power packs and PLC (Programmable
Logic Control) technology to enable automatic
control and operation.
The recently introduced TopLoader system
provides a further solution to enable the improved
handling of bulky recycled materials such as wood
waste, compost and shredded paper/cardboard
fibres. One of the key advantages of this system is
that it does not require the construction of deep
pits and that all moving parts are located above
the material being loaded – so there is no direct
contact with abrasive materials. With low energy
costs, the TopLoader system can handle a wide
range of materials, is completely automatic
and enables trucks to back right up to the unit
for loading with a much-reduced likelihood of
damage or accident compared with some existing
systems.

The Finland-based Hiab group has announced
that operators of its new Multilift XR Power range
of hooklift demount systems are reporting quicker
turnaround times and higher vehicle utilization.
This is thanks to a series of customer specifiable
options that enable the recently introduced
units to be more closely tailored to operational
demands.
But the big gains are in improved safety,
comfort and ease-of-use for the driver. All new
XR Power hooklifts are controlled by a PLC
(Programmable Logic Control) system that is
mounted in a newly-designed console. This is
clipped to the driver’s seat or can be used with a
‘wanderlead’ i.e. attached to the host machine by
a flexible cord.
The new control panel is not only easier to use,
but it can be tailored to meet the demands of the
job without the need for expensive modifications
to the truck’s own dashboard control panel.
The Multilift XR Power range offers a two
speed hooklift and slide capability – enabling
lightweight or empty containers to be lifted more
quickly, while dialling-in maximum hydraulic
torque to lift heavier units slowly and accurately.
A ‘friction relief’ option is designed to reduce the
sometimes unpleasant noise levels when a fully
loaded older container is lifted.
Alternatively, the customer can specify
proportional speed control, whereby the hydraulic
system will select the fastest, most efficient
speed for any operation taking into account the
weight of the load. A third control option – fully
automatic – is likely to prove popular for operators
using agency drivers without extensive hooklift
experience, as it affords an added safety bonus.
The XR Power range has further advantages:
the complete unit is painted and/or coated prior
to assembly to ensure maximum durability, and
is supplied with a mounting
kit for rapid and weld-free
mounting. At the same time,
additional equipment such as
bogie blocking cylinders (to ‘fix’
truck suspension systems during
loading), container covering
systems and trailer controls can
be programmed into the PLC as
required.

Visual Management, part of the AD Group. RemGuard has
been at the forefront of remotely monitored CCTV in the UK
for more than a decade, continually improving and refining
the service it offers. And the perspectives below draw upon
RemGuard’s experience in this field.
The latest trends in intelligent CCTV
Remotely monitored or detector-activated CCTV is at the
forefront of this trend and, in the UK at least, it will inevitably
be more widely applied now that there is a British Standard (BS
8418) in place to support best practice. This type of CCTV
really comes into its own overnight, where attacks by hardened
criminals and petty vandals can pose the greatest problems for
sites, which are often positioned well away from public view.
In practice, with remotely monitored, detector-activated
CCTV, detectors are placed strategically around a location and
linked by transmission equipment to a remote video response
centre (RVRC). Here operators can provide 24-hour eventdriven monitoring of a specified area without the need and cost
of having guards permanently on site.
When detectors are triggered, images from on-site cameras
are automatically transmitted – typically via internet broadband
connection – to the RVRC. Operators are able to confirm what is
happening and even issue verbal warnings via on-site speakers –
talking CCTV – to warn off intruders. Experience suggests that
this step alone is a sufficient deterrent in over 90% of incidents.
Where offenders are more determined, operators can alert the
emergency services and key holders.

Of course what really matters with any security technology
are the practical experiences of people on the ground; below
are some examples of sites where the application of remotely
monitored CCTV monitored by a BS8418-compliant RVRC
has made a real difference to event detection and deterrence.
Metal madness
Operators at RemGuard’s Remote Video Response Centre (RVRC)
sites that may previously have shied away from this technology
and relied instead on conventional intruder alarms, where
false activations are a recurring problem. Also from a police
perspective, it is naturally preferable for an operator to be
able to see what is going on – as opposed to the more limited
information provided by an intruder alarm.
The latest solutions even allow site managers to have direct
access to the system from a local PC. This allows authorized
personnel to view live and recorded images during working
hours when the remotely monitored service may not be active,
or at home in the evening when informed of an incident by the
RVRC.
As the theft of metal continues to hit the headlines, with
everything from statues to church roofs in the firing line, one UK
company is fighting back thanks to remotely monitored, detectoractivated CCTV. Oldbury Aluminium Alloys is engaged mainly
in the manufacture of secondary aluminium alloy ingots and
operates a scrap recycling business for a number of blue chip
companies. To address the ongoing threat, the West Midlandsbased company is applying sophisticated event-driven CCTV
technology to help protect its headquarters against the dramatic
explosion in attacks across the country. Oldbury is one of an
increasing number of sites to adopt this solution for ‘out of
hours’ security, in preference to more traditional options such as
manned guarding or CCTV recorded for later review.
Managing Director Jonathan Gadsby commented: ‘The
nature of our business, processing valuable metal, means that
we are an attractive target, so effective security is of paramount
importance.
‘Sadly in our local area there is a high theft rate for scrap
metal and metal theft of all types is up 112% year-on-year.

them, in an industrial estate like ours, criminals are more than
willing to attempt to climb over a fence onto site and grab
specific items – often stealing to order – and then selling these
on for cash. In terms of scrap metal there are always some less
scrupulous operators who are quite happy to melt down scrap
with no questions asked especially given the rise in metal prices.
At Oldbury we only ever buy our scrap metal from known
sources.’
A key benefit for Oldbury is the ability of the CCTV solution
to prevent unexpected downtime, caused by attacks, with all the
consequent disruption to business and the potential impact on
insurance premiums. According to Gadsby a number of incidents
have underlined the value of the remotely monitored CCTV: ‘In
one case a gang broke into our site during the night by climbing
an external fence. Thankfully two individuals were spotted by
operators at the RVRC who alerted the police and one of our key
holders. The police were then able to bring their dogs onto our
site to track down and detain one of the intruders at the scene.
Without prompt action we could have faced considerable losses
and disruption to business.’
In another incident, over a weekend, when a detector was
activated, operators at the RVRC realised that one of the cameras
on site had been knocked out of position. With the help of the site
plan stored on their system and other cameras, they were able to
track down an intruder and alert the police. As the incident had
been confirmed visually, the police quickly attended the site and
arrested an individual plus another suspect found nearby.

The installation of an Envac system leads to a drastic reduction of on-road transportation of waste, improved hygiene and

Replica gun incident
Premier Waste (UK) Ltd is another business active within the UK
waste sector which has adopted remotely monitored, detector
activated, CCTV, in this case to secure its extensive waste
management and recycling site in Hyde, Greater Manchester.
The facility hit the headlines last September when CCTV
images were shown in the media of a teenager aiming what
appeared to be an AK47 rifle from the adjacent Newton Railway
Station. The company’s crane driver spotted two youths acting
suspiciously, one of whom seemed to be pointing a rifle in his
direction, and radioed Frank Ridley, a Director at Premier Waste
(UK) Ltd, who was able to control the CCTV locally using
the viewing software supplied with RemGuard’s transmission
equipment to take a closer look at the scene as well as contacting
both Greater Manchester Police (GMP) and RemGuard.
Although the incident happened during the day, according
to Ridley, the RVRC provided invaluable assistance: ‘They were
able to supply images of the youths which we presented to the
police. The footage also helped to bring about the arrest of the
suspects with a 15-year-old given a final warning and a 17-yearold a community order. Although it turned out that the AK47 was
a replica there was no way of us knowing this at the time. It was
certainly good to have RemGuard’s help and advice to turn to for
what seemed, on the face of it, to be a much more serious event.’

business, said Ridley: ‘We have a large 20-strong fleet of biofuelled vehicles parked-up on site which need to be protected at
all times. If the trucks are damaged they may have to be taken
out of service, leading to unplanned downtime and a knock-on
effect on our customers waiting for their skip to be delivered or
waste collected. Alongside this, the CCTV solution needs to be
able to prevent criminals stealing our valuable garage equipment
– used for vehicle maintenance – and stop unauthorized access
to our offices.’
There have been a number of out-of-hours incidents were
the service has proved particularly helpful. ‘The fast response
of operators at the Remote Video Response Centre secured an
arrest and conviction in one of the incidents. We also used to
have problems with youths coming into the yard and hotwiring
the vehicles. They couldn’t actually move them as we have
an air immobilizing system, but coming in the next morning
to find most of the lorries running was extremely frustrating
– never mind the cost of the fuel. The good news is that because
of the RVRC’s vigilance this kind of incident has stopped
completely.’
Ridley also stresses the role that the latest surveillance system
has in keeping employees safe on site. ‘Given the nature of our
business the CCTV solution has proven extremely helpful in
allowing me to monitor staff – with their agreement – for health
and safety compliance. It has also been successful, when the
remote monitoring and loudspeakers are applied, in stopping
young kids using our site as a playground when we are shut
down at night or during the weekend. Our own employees are
well trained to deal with the waste on site and handle the heavy
equipment, but it is certainly not an environment we would want
children running around in – for their own safety.’
Securing the future
Ultimately, when it comes to securing recycling and waste
sites from attack by opportunists and hardened criminals, the
flexibility and economics of ‘intelligent’ remotely monitored
CCTV which meets the latest BS8418 standard seems certain to
win more and more converts.
And, while of course few would welcome any form of
escalation in criminal activity, such a trend does at least
point toward the value inherent in waste. Earlier this year
the International Iron and Steel Institute reported that steel
cans remain the world’s most recycled packaging material. In
2006, 6.6 million tonnes of steel cans were recycled, across
the 35 countries represented in the data collection. If one
extrapolates from the business being done with this item
alone, it is no surprise that security is an important issue
going forward.

MEETING MARKET DEMANDStBIOWASTE
Box 1: Anaerobic digestion in the UK
In April the UK Environment Agency (EA) and WRAP (Waste & Resources Action Plan) published a draft protocol on anaerobic
digestion. The document is out for consultation until 27 June. ‘The quality protocol for the production and use of quality outputs
from anaerobic digestion of source-segregated biodegradable waste’ aims to inspire confidence in the products made from waste
in order to develop a market for these products, encourage increased recovery and recycling and thereby divert material from
landfill. Among the main obstacles to increased development of AD facilities are uncertainty over what constitutes waste and
the fact that the products of anaerobic digestion – whole digestate, the separated fibre fraction and the separated liquor – are
still classed in the UK as waste. This has hindered the development of a market for materials produced from waste, and has also
adversely affected recycling rates and diversion from landfill. The introduction and acceptance of a quality protocol are seen by
many in the industry as key steps in its development.
The protocol is part of the Waste Protocols Project, a joint initiative between the EA and WRAP in collaboration with industry,
and funded by the UK government. The aim of the Waste Protocols Project is to identify the point at which materials cease to be
waste and are, therefore, not subject to waste regulation controls. In March 2007 the EA published the UK’s first quality protocol
for compost, which sets out the criteria for the production of a quality compost from source-segregated biodegradable waste. The
new protocol will do the same for anaerobic digestion.
The thirty-page quality protocol sets out criteria for the production of useable by-products of the anaerobic digestion process.
If all the criteria are met, the ‘quality outputs’, as they are called, will be considered to have been fully recovered and therefore no
longer waste when it is despatched to a customer. The quality protocol also sets out strict guidelines on the input materials that
can be used in the digestion process and the uses to which the resulting products can be put. These ‘designated market sectors’
are agriculture and forestry (excluding horticulture), and land restoration. The quality digestate can be used as a soil improver or
fertilizer, for soil manufacture/blending and for land reclamation processes such as contouring, reconstruction, re-vegetation and
so on. The protocol qualifies this further by stating that if it cannot be demonstrated that the digestate will be used in one of the
designated market sectors, then the AD products will be classed as waste.
Interested parties have until 27 June to respond to 25 questions relating to the technology, an approved composting standard
(PAS 110), and the financial impact of the protocol, which is expected to be implemented on 1 September. A pdf of the quality
protocol can be downloaded at http://qpyr1.dialoguebydesign.net/docs/QP_AnaerobicDigestion.pdf
Investment in AD
The UK government’s Waste Strategy 2007 identified anaerobic digestion as an effective way of recycling food waste and proposed
further support for the process via the New Technologies Demonstrator Programme (NTDP). And, more recently, in February this
year the government announced an increase in funding for clean energy technologies to over £400 million ($788 million) over
the next three years – including £10 million ($20 million) for a new anaerobic digestion demonstration programme. Furthermore,
funding for AD facilities is also offered via the Capital Grant Programme managed by WRAP and the Welsh Assembly’s Materials
Action Programme (MAP), which can fund up to 30% of capital set-up costs.
Sarah Wisson, Waste Management World
tended to focus on the treatment of sewage sludge and agricultural
manures. More modern plants have been developed to process
MSW, industrial solid wastes and industrial wastewaters, but
impurities and the varying content of lipids, proteins and
carbohydrates can cause problems. As a result, a pre-treatment
step, involving removal of impurities and particle size reduction,
is needed to allow stable digestion performance.
The substrate is key
Wastes of the type mentioned above can be characterized
according to their COD concentration. COD refers to the total
quantity of oxygen required for oxidation to carbon dioxide and
water and is a measure of the organic content of the waste.
Systems have been invented to process substrates with a minor
COD concentration (<25gO2/litre raw material), for example:
rVQGMPXBOBFSPCJDTMVEHFCMBOLFU6"4#
rFYQBOEFEHSBOVMBSTMVEHFCMBOLFU&(4#
rJOUFSOBMDJSDVMBUJPO*$
A completely stirred tank reactor (CSTR) or plug-flow-tank
reactor (PFTR) is used to treat substrate with a high COD
concentration, and high content of fat, lipids and particles.
Such fermenters tend to operate with low loading rates –
when compared with the systems developed for minor COD
concentration – in order to guarantee complete anaerobic
digestion. COD loading rate is the daily quantity of organic
matter, expressed in COD, feed per m3 digester volume per day
i.e. kg COD/m3/d.
One of the important goals for industry has been to develop
a technology to treat both large volume streams and complex
high concentrated substrates. And one company believes that it
has solved this puzzle.
The Enbasys approach
Enbasys, based in Grambach, Austria, has developed a
technology called a High Load Hybrid Reactor that is designed
to handle large volume treatment of different organic waste and
biofuel residue streams, which include complex substrates. The
technology unifies a classical digester system (high total solids
and COD content of the substrate) with high performance
digesters (UASB). The combination of process, fermenter

and mixing technology makes it possible to process various

– thus supporting continuous operation.
Its technology was first installed in north Italy in 2005 and
has been operating continuously for three years. The plant in
Italy consists of two 2900 m3 fermenters which process 120,000
tonnes of pre-treated organic waste per year. This results in a
loading rate of 12 to 15 kg COD/m3/d from which 1250 Nm3/h
biogas is produced. The biogas is used to run a combined heat
and power (CHP) plant with 3.0 MWel. Studies conducted by
Enbasys for this article of 33 MSW anaerobic digestion plants
worldwide, built since 2004 or still under construction, have
shown that the average fermenter volume is about 6220m3
converting 54,900 tonnes MSW into biogas. This equates
to 9 tpa (tonnes per annum) per m3 fermenter volume. The
Enbasys plant in Italy processes 21 tpa pre-treated organic waste
per m3 fermenter volume, giving a higher system efficiency
(specific waste throughput) than conventional plants.
The High Load Hybrid Reactor technology represents the
culmination of more than 10 years of experience in design,
engineering, building, operation and research in the field of
anaerobic digestion technology. To spread this new generation
technology internationally the inventors needed a strong partner,
which they found in VTU Holding. Enbasys is a subsidiary of
VTU Holding. Contracts for the foundation of Enbasys GmbH
were signed in August 2007.
In January 2008 BDI BioDiesel International AG acquired
an interest of more than 25% in VTU Holding GmbH. BDI

Box 2. An evolving regulatory framework for AD
technology suppliers in Europe
The EU policy on sustainable energy dates back to a Council
resolution in 1986 to develop new and renewable energy
sources.
In 1997 a ‘White Paper on renewable energy sources’ was
published by the European Commission. This set a target of
12% of gross inland energy consumption from renewables
for the EU-15 by 2010, of which electricity would represent
22.1%. With the 2004 enlargement, the EU’s overall objective
increased to 21%.
The EU has committed to reducing its overall GHG
emissions to at least 20% below 1990 levels by 2020. And
the climate action and renewable energy package published
earlier this year sets out sustainability criteria that biofuels
must meet to ensure they deliver real environmental benefits.
In the waste sector the EU landfill directive (1999/31/EC)
requires the reduction of biodegradable municipal waste
going to landfills to 75% by 2006, 50% by 2009 and 35%
by 2016 calculated on the basis of the total amount of
biodegradable municipal waste produced in 1995.
In February 2007, the European parliament adopted a
resolution on a revised Waste Directive. In April 2008, the
Environment Committee of the European Parliament voted
on this Directive (see comment on page 8).
Further national regulations include strategies and
limiting values intended to promote successful and
sustainable operation of biowaste treatment facilities.

AD cost effective, with high gate fees for wastes and special
premium prices paid for the production of renewable energy.

biodiesel production plants, with expertise in a range of raw
materials, such as vegetable oils, waste edible oils and animal
fats. Enbasys GmbH therefore benefits from the long established
engineering expertise of VTU and the know-how of BDI in
international plant supply and construction.
The development of AD in Europe
It is perhaps not surprising that new companies specializing
in AD are emerging in the European market, where there has
been active political interest in promoting industries that link
Biomass currently meets 4% of the European Union’s energy
needs – that is 69 million metric tonnes of oil equivalents (toe).
According to the European Commission’s Biomass Action Plan
this should be increased by 2010 to 150 million tonnes of oil
equivalents.
An increase of this magnitude could bring the following
benefits: diversifying Europe’s energy supply; significantly
reducing greenhouse gas emissions (209 million tonnes); direct
employment for 250 to 300,000 people; and potentially lowering
the price of oil as a result of lower demand.
The majority of municipal waste in the EU is currently
disposed of through landfill (49%), followed by incineration
(18%) and recycling and composting (33%). In the new Member
States the situation is evolving rapidly but landfill is still the main
destination for MSW. According to the European Environment

content and reduced fertility.
The most practical environmental solution will be deriving
energy from waste, not only municipal solid waste but also
the residues industry. Anaerobic digestion has significant
potential for industries with organic waste streams, such as
food processing, the paper and textile industry, pharmaceutical
industry and biofuel production. Anaerobic digestion combines
several advantages. As a technology it can be regarded as
being ‘CO2 neutral’ because there is no net addition of CO2
to the atmosphere. The Enbasys High Load Hybrid Reactor
could be the key to developing the potential of AD as a waste
management strategy. It degrades waste while producing biogas
and a fertilizer product that contains a high nutrient content
(nitrogen, phosphorus and potassium), but in order for the full
potential of the waste/organic substrate/input to be realized, it
is vital that the waste management industry is able to develop
markets for all the by-products.

Combining oxidation

further steps by applying
WAO in conjunction with
alkaline hydrolysis. Alkaline
hydrolysis technologies have
been extensively used in
the chemical industry (for

various fields – in particular
chemistry, mechanics and
biology – BioCorrection has
identified what it regards as
an ideal mix of temperature,
pressure and processing time.This
‘ideal mix’ has made it possible to
facilitate the conversion of waste into
products with commercial potential.
Today BioCorrection is looking to
introduce its proprietary OHD technology
to the European and American markets,
aiming to transform various organic wastes
(animal farm wastes, industrial and municipal
wastes) into two main by-products:
rBTPMVUJPOPGIVNJDTVCTUBODFTBMJRVJEPYJEBUF
rBTPMJESFTJEVF
An OHD plant can process a variety of organic wastes to produce a liquid
oxidate and a solid residue. There is a developing market for both of these
by-products
To reiterate, this transformation is achieved at high
temperature and pressure, thus ensuring full decomposition of
organic wastes and chelating of initial pollutants in the resulting
products.
The process in more detail
Essentially, oxidative-hydrolytic-destruction (OHD) is a kind
of wet-air oxidation technology (WAO) based on an approach
patented in the 1930s and developed in the mid-1960s to reduce
the ecological impact of wastewater treatment facilities in the
Russian Federation. It involves the oxidation of dissolved or
suspended components in water (using oxygen as the oxidizer).
Oxidation reactions occur in superheated water at a temperature
above the normal boiling point of water (100°C), but below the
critical point (374°C).
Wet oxidation has been applied commercially for around
60 years, predominantly for treating wastewater, but also
in the treatment of caustic soda, wastes from oil refineries,
pharmaceutical industry wastes and other toxic wastes. Usually
the by-products of the WAO technologies require postpurification to remove remaining toxic substances, such as
heavy metals. With this in mind WAO can be considered the first
step in the chain of disposal measures.
48
WASTE
management world
Much like a standard wet-air oxidation plant, the OHD plant
includes an input tank and a pressurized tank, otherwise known
as a reactor, in which the main reactions occur (see also Figure
1). The input tank is used to prepare the feedstock pulp, which
contains a controlled mixture of organic waste (with 5%–15%
dry matter) and hydroxide. Conditions inside the pressurized
tank are carefully controlled – at a pressure of above 20 bars and
a temperature of over 180°C for several hours. Oxygen is also
present to ensure successful oxidation of the material.
In these conditions, compounds present in the initial waste
(mono- and disaccharides, proteins and fats) are exposed to
oxidative destruction – either complete, with formation of
CO2 and water, or partial with formation of monomers. Other
organic compounds that are more difficult to hydrolyze, such as
lignin or cellulose, are also partially oxidized in the course of the
OHD process and form the skeleton of the OHD by-products.
A sedimentation process takes place (in separate tanks)
during which the heavier fraction, containing heavy metals

(lead, zinc, cadmium, mercury) precipitates and is thereby
separated from the lighter fraction. This lighter fraction is called
the oxidate or humic substance. The heavier fraction is the
unoxidized residue.
This physical process does not achieve complete separation
of the oxidized and unoxidized parts, but the chelating properties
of the oxidate (humic substance) mean that any traces of heavy
metals in the unoxidized residue that remains mixed with the
oxidate are bound in a stable form and therefore cannot be
released by leaching.

WA S T E L E A D E R S t HERNAN CARLINO
Tackling climate change
Hernan Carlino is an economist and Chair of the Clean Development Mechanism
accreditation panel at the United Nations. Here he discusses climate change issues
from the perspective of the waste management industry
Climate change is currently at the top of the agenda – how do
you think this debate will influence the waste industry?
Climate change is at the top of the political agenda both
nationally and internationally. However, I do not think that this
pre-eminence is temporary, or likely to change soon. In fact,
the consolidation of an international climate change regime is
inevitably setting up the rules for the establishment of a carbon
economy that will dramatically transform the current paths of
economic development. And a clear long-term carbon price
will be the main signal that this process is effective in tackling
climate change and is being internalized by economic players
everywhere. Remaining discussions should now be focused on
the nature of the policies put in place and the instruments to
be used to address climate change at the international and local
level.
The waste industry has a key role to play in the mitigation of
climate change due to the relatively large share of greenhouse gas
emissions from waste management and due to its global nature –
one way or another, waste and waste management are a part of
the core societal activities of production and consumption. Thus,
the challenge posed by climate change to economic activities and
the need to identify ways in which to deal with it effectively will
inevitably be extended to the waste industry.
The main ways in which the waste industry can contribute to
mitigating climate change are related to optimizing processes for
the treatment of waste flows and energy conversion. Spreading
the message about the need for sustainable consumption is also a
task to be taken up by the waste industry.
What are the key challenges for the waste sector in terms of
greenhouse gas emissions?
At the global level there is a clear need to participate in and
contribute to designing an architecture that requires effectiveness
and fairness, by means of the hands-on expertise and know-how
the waste industry has accumulated. Flexibility, technological
innovation and the will to adapt to a changing regulatory
environment are equally important.
At the national level, the waste industry, particularly in
developing countries, can play a proactive role by facilitating
participation in the mechanisms that are already in place to
address the problem. In addition, particularly as resource
constraints are stronger in those countries, it is necessary to ensure
that investment decisions are taken with proper consideration of
the opportunities provided by carbon markets.
Waste management and greenhouse gases
Waste management generates carbon dioxide and methane,
with emissions occurring during almost all stages of waste
management, from transportation through to recycling,
recovery and final disposal; however, they can be reduced in a
number of ways. For example:

initial approaches might not have been entirely successful or
appropriate for achieving the proposed goals. In any case, we
need to accelerate the learning process while seeking efficient
solutions to the problems of climate change.
What role do you think market-based mechanisms, such as
taxes, CDM and so on, can play in the limiting of greenhouse gas
emissions from the waste industry?
As climate change appears to be both the ultimate cross-sectoral
issue and a global challenge, it requires a global framework to
avoid inconsistencies and facilitate the transformations that are
the prerequisite of the vast, even dramatic, emissions reductions
required to address climate change.
Market mechanisms, current and in development, and carbon
prices are the linchpin between economic activities as they are
performed in the present and a ‘new’ world in which renewable
energy, absolute energy efficiency, carbon capture and storage,
maximized recycling and sustainable consumption are the
dominant patterns. The waste industry can and should advance
these transformations, ameliorate the transition and diminish
the costs of its materialization by fully employing its array of
resources.
To what extent do you think policy – and decision-making are
based on sound scientific knowledge?
There is a robust base of scientific evidence. Of course there are
uncertainties – this is a learning process for everyone including
decision makers and policy designers; hence, some of the
