An Assessment of WRAPs Tyre Programme and a Forecast of the UKs Used
Tyre Market up to 2015 1
Executive SummaryEnvironmental Resources Management Ltd (ERM) was commissioned by WRAP to carry out a project with the
following two specific objectives:
1 to review the impact of the three year WRAP Tyres Programme and to assess its effectiveness in terms of
successes, failures and missed opportunities.
2 to carry out forecasts up to 2015 for the UK used tyre market. The aim was to suggest the predicted
tonnage growth or decline in the main UK used tyre sectors based on current trends, perceived economic
changes and information from the used tyre industry. It included consideration of the maximum and
minimum market potential for the main UK tyre sectors up to 2015.
In order to gain feedback from the tyre industry on the WRAP three year programme, ERM sent key stakeholders
a detailed questionnaire asking for their views on the Programme. ERM also asked stakeholders to predict how
the industry was seen to be progressing and which management routes they felt were going to decline or grow.
The response rate to this questionnaire was not as high as expected but the feedback received was valuable and
provided a good insight into the effectiveness of WRAPs tyre programme and the industry overall.
WRAPs Tyres Programme was generally very well received by stakeholders with over half of those who
responded stating that the overall programme had been effective. There were a small number of negative
comments relating to the promotion activities associated with some projects and how projects were selected for
funding. Feedback on the Publicly Available Specification (PAS) documents was very positive and stakeholders
recognised these as the most successful publications. Nearly all respondents who mentioned these documents
felt that they had had a significant impact on the tyre industry. Stakeholders felt that the Tyres Programme had
provided a useful awareness raising and information provision tool.
ERM created a number of scenarios to illustrate how the used tyre industry is likely to look up to 2015. These
scenarios were based on ERMs knowledge of the industry and feedback from key stakeholders.
In terms of changes to the market in the future, ERM believes that the tonnage of tyres sent for retread andreuse will remain fairly constant with a reduction occurring in the export and landfill engineering market. The
recycling industry is likely to grow as demand for rubber for use in road surfacing or construction increases and
as new and emerging technologies such as cryogenics come in to the market. It is believed that energy recovery
through burning tyres in cement kilns will remain strong due to a continued need for more environmentally sound
alternative fuels.
The greatest impact on future management routes for used tyres is likely to be from changes to environmental
policy and legislation. The banning of tyres (whole and shredded) from landfill has meant that alternative
markets have needed to be found to dispose of used tyres. Similarly, legislative controls would impact on the
future management routes of used tyres, with excess tyres needing alternative disposal or management routes.
Climate change policies are also expected to have an impact on future markets. The carbon footprint of products
is clearly on the environmental agenda and processes that result in a reduction in carbon dioxide such as
retreading and reuse are likely to be considered more favourably by the industry as a whole.

Introduction
1.0 Project Objectives
WRAP commissioned ERM to carry out a project with the following two specific objectives:
1 to review the impact of the three year WRAP Tyres Programme and to assess its effectiveness in terms ofsuccesses, failures and missed opportunities.
2 to carry out forecasts up to 2015 for the UK used tyre market. The aim was to suggest the predicted
tonnage growth or decline in the main UK used tyre sectors based on current trends, perceived economic
changes and information from the used tyre industry. Further to this, it intended to consider the maximum
and minimum market potential for the main UK tyre sectors up to 2015.
2.0 Approach
ERM sent a detailed questionnaire to key stakeholders in the industry as agreed with WRAP. This questionnairesought feedback from the stakeholders on the impact of WRAPs three year Tyres Programme.
In order to develop a series of possible projections for the future handling of used tyres up until 2015, ERM
carried out desk-based research into factors which can impact on:
the volumes of used tyre arisings; and
the different methods of managing used tyres.
The stakeholder questionnaire also sought views on how the waste tyre industry is likely to change in the future.
It was also used to gain insight into the perceptions of the future markets of used tyres, and to provide
stakeholders with the opportunity to comment on how they felt the future would look in terms of disposal routes.
A copy of the questionnaire is provided in Appendix 1.

Review of WRAPs Tyre Programme
3.0 Introduction to WRAP s Tyre Programme
WRAP funded a broad range of projects including the development of two PAS documents on tyre bales for use in
construction and the manufacture and storage of size reduced tyre materials, demonstration trials (such as theuse of post-consumer tyres to deliver sustainable construction of public rights of way), operational trials (such as
testing the incorporation of a new kind of ultra-fine crumb rubber into truck tyre compound) and R&D projects
(such as determining if crumb rubber would be a suitable aggregate replacement in concrete blocks and
assessing technical and operational details of waste tyres in landfill engineering applications).
Individual projects may address one of more of the overall aims of the Programme. The main objectives of the
WRAPs Tyre Programme were to:
Break down the barriers to the collection, segregation and reprocessing of waste tyres;
Develop alternative end uses for the recovered material; and
Develop the end markets for this material.
WRAP suggested five further objectives which were:
Market development;
Support funding;
Raising awareness;
Providing information; and
Overcoming legislative barriers.
ERM carried out a high level review of all WRAPs project outputs with the aim of assessing which have met
WRAPs objectives. ERM also sought feedback from stakeholders on the impact of the Programme via the
questionnaire in relation to these objectives (see Section 5.0).
4.0 Review of WRAP Projects
ERM assessed all 82 project outputs provided on the WRAP website that were commissioned over the three year
period against the overall aims and objectives of the Programme. ERM reviewed and assessed each publication to
determine whether they met WRAPs objectives. This high level review was done by a simple tick box exercise
against the five WRAP objectives: market development; support funding; raising awareness; providing
information; and overcoming legislative barriers. The results of this review are presented in Appendix 2.
The majority of the publications could be considered to meet theproviding informationand raising awareness
objectives as outputs were all published on the WRAP website and all intend to provide information on the project
or event to which they relate. The Stakeholder Forums provided a good means of networking and although not
necessarily raising awareness of the overall tyres industry, they enabled the different sectors to become moreaware of the Programme and the activities of other industry sectors.
PAS 107 and 108 met a number of WRAP objectives and were received favourably by the industry. They provide
information and are a means of regulating the industry in terms of ensuring that tyre bales and grades of rubber
are of a consistent and verifiable quality. In this sense they could also be considered to meet the objective of
overcoming legislative barriers. Methods which address better regulation in the sector result in improved
confidence in products. This helps stabilise markets and thereby helps to reduce market impacts such as the
Landfill Directive and End of Life Vehicles (ELV) Directive. Both Directives have increased the number of used
tyres needing alternative management.
Project TYR010 (UK Used Tyre Market 2004) is likely to prove useful to policy makers through the provision of
forecasts and market disruption planning scenarios.

From our assessment of the WRAP projects, it was clear that all case studies met the market development
objective as they were generally involved with research and development and were carrying out trials on
emerging ways of reprocessing and reusing tyres. A number of these projects also received support funding.
Table 1 below provides a list of all case studies on the WRAP website.

Projects involving different types of surfaces such as roads, rights of way, sports surfaces and landscaping were
generally all seen toprovide information. Some reports were considered to meet the objective ofmarket
developmentand others had received supportfunding.
The retread projects such as the Powder in Truck Tyre Retreads case study met the market developmentand
providing informationobjectives as they explored different uses for the powder. Other retread projects all were
considered toprovide information.
All publications and projects focusing on emerging technologies also met theproviding informationobjective.
The Market Study on the Demand for Char from Tyre Pyrolysis identifies a wide range of potential market outlets
for pyrolysis char in the UK and therefore could be considered to meet the market developmentobjective.
5.0 Stakeholder Feedback on WR AP Tyre Programme
70 tyre stakeholders were sent a detailed questionnaire asking for their views on the three year WRAP Tyres
Programme and on future markets for used tyres. 27 stakeholders (39%) responded and of these three did not
feel able to provide meaningful answers to the questions. Although this response rate is quite low, those who did
respond provided useful feedback on the WRAP Programme. This Section provides a summary of theseresponses.

5.1 Where has WRAP had the most and least influence?
Stakeholders were asked where they felt WRAP had had the most or least influence. They were asked to rank
which industry/product areas were most and least influential in terms of the following five objectives:
Market Development;
Support Funding;
Legislation and Standards;
Raising Awareness; and
Providing Information.

Figure 1 shows that according to stakeholders WRAP has had most influence in providing information and on
legislation and standards the PAS documents were specifically mentioned by a large number of respondents.
Stakeholders commented on how WRAP had enabled a number of R&D projects to be funded, however they felt
it was too early to say if the Programme had impacted on market development. ERM recommends that WRAP
should repeat this question to the sector in a few years time when the industry has had time to develop further in
these areas.
5.2 Which WRAP projects have been the most and least valuable?
Stakeholders were asked which WRAP projects or initiatives were most and least valuable.
PAS 107 and 108 were generally very well received by the tyre industry. According to stakeholders, they have
been the most successful projects WRAP has commissioned. Stakeholders felt that these documents were of
most significance to their companies and had genuinely made a difference to the way in which the construction
industry views tyre products. The availability of standards helps break down market barriers, keeps the industry
properly regulated, allows businesses to show they are meeting industry expectations and ensures consumer
confidence.
Some stakeholders felt that the promotion of these documents could have been better. It was felt that
opportunities were missed with PAS 108 as it was not promoted in the relevant publications and therefore the
overall impact of the document was less than it could have been. These stakeholders were exclusively from the
used tyre reprocessor sector.

Despite this feedback, the stakeholders indicated that these two publications provided the industry with an
excellent piece of workthat will ensure the production of consistent products and that quality control is
maintained.
Two further respondents (not within the used tyre reprocessor sector) felt that the promotion of projects was
sometimes not adequate. Both of these respondents stated that this could have been due to either their location
or the fact that they do not work solely in the waste tyre industry, however, it is evident that there is potential for
improvement in this area.
The WRAP website was generally favourably received and stakeholders felt that it was very informative and
provided a wealth of material. However, one respondent felt that it was not very user friendly and would have
benefited from a summary and list of all the reports and projects undertaken. It was felt that WRAP had
contributed significantly in the provision of tools and research that could be used by specific markets rather than
providing any direct impact in market development. One respondent felt that it was down to the individual
sectors to make the best use of the resources provided by WRAP.
There were differing viewpoints on the way WRAP had funded certain projects. In some cases, it was felt that
money had not been well spent and better consultation should have been carried out before selecting projects to
fund. Some stakeholders felt that businesses should not receive any funding. Responses in this vein were
received from trade associations and used tyre reprocessors.
Other stakeholders felt that more funding would have been beneficial and would have resulted in larger R&D
projects and that more capital funding and promotional work was still needed. These responses came from a
variety of sectors including used tyre reprocessors, trade associations, consultancies and technology developers.
One stakeholder felt that although the work on tyre bales and roof tiles was very goodit could have been
promoted more effectively.
5.3 Could the Programme have been improved in anyway?
Stakeholders were asked how WRAPs tyre programme could have been improved. A small number of
respondents felt that support funding could have been improved in terms of how the decision process was carried
out and the fact that there should have been more funding for R&D projects. One respondent suggested that the
allocation of funding should have been a two-tier process so that successful R&D projects should be eligible toreceive more funding in a second commercial development phase. As mentioned in Section 5.2 above, these
responses were from a number of different sectors.
Nine respondents felt that more should have been done in their specific area and of those, four were from the
used tyre reprocessing sector.

Figure 2 shows that there was some uncertainty as to whether the WRAP Programme needed to be improved.
40% of respondents (8 out of 20) felt that minor improvements were necessary. Respondents were unsure as to
the relevance of this question in view of the fact that the Programme was coming to a close.
It was felt that the Programme would have benefited from being five years rather than three years and that it
would have been improved if there had been the opportunity to draw lessons from what had been done.
5.4 Was the Programme resourced adequately?
Stakeholders were asked whether they felt the Programme was resourced adequately. 87% (20) of those who
responded to the questionnaire answered this question. Over half (11 respondents) felt that it had been
resourced well with only four stating that it had been under resourced.

5.5 What impact did WRAP have in relation to the breakdown of barriers to the collection,segregation and disposal of waste tyres?
Stakeholders were asked how WRAPs programme has impacted on barriers to the collection, segregation and
disposal of waste tyres.
Figure 4 shows the number of respondents who felt that WRAP had impacted on the breaking down of barriers to
the collection, segregation and disposal of waste tyres. There were no negative responses; however the data
shows that the majority of respondents were unsure. Stakeholders were not willing or did not feel happy to
speculate whether WRAP had positively or negatively impacted in this area.
Those who responded positively felt that market transparency had been improved by the work on charges and
market scenarios and that one of the biggest barriers to the industry is lack of awareness. It was felt that WRAP
had increased awareness in these areas, although that there was still room for improvement.

5.6 WRAPs influence in developing alternative end uses and end markets for used tyres
In terms of developing end uses it was felt that WRAP had been influential in some areas through its support
funding of various R&D projects and its provision of market and technical information. Specific end uses that
stakeholders felt WRAP had helped to develop included roof tiles, using rubber in plasterboard and using ultra
fine ground post consumer tyres in truck tyre retreads. However it was felt that WRAP had not been particularly
influential in other areas, such as using rubber in roads, and that more could have been done to develop
materials to be used in construction.
From Figure 5 it is clear that the majority of respondents felt WRAP had had neither a positive nor a negative
influence in developing end markets for used tyres. WRAP has helped promote alternative solutions but it wasfelt that the final impact of these new markets would be dependent on current markets accepting these new
materials or products. According to one stakeholder, WRAPs contribution was more in the area of providing tools
and research rather than having any direct impact in market development. The respondent felt that it was the
responsibility of the individual sectors to make the best use of the resources provided by WRAP. Overall, it was
felt that in terms of general awareness raising and provision of information WRAP had been influential, although
two respondents felt that WRAP had not been at all influential in developing end markets and that there had been
no significant increase in the volume of recycling capacity within the UK.

6.0 Key Conclusions of Review of Tyre Programme
Overall stakeholders received the WRAP Tyres Programme favourably and felt it provided a useful awareness
raising and information provision tool. There were a small number of negative comments relating to how some
projects were promoted and how projects were selected for funding. The publications recognised as being the
most successful were the PAS 107 and 108 documents. Nearly all respondents who mentioned these documents
felt that they had had a significant impact on the tyre industry.
Respondents felt that the website was a good source of information but that it was up to the individual sectors to
make the best use of the resources that have been provided. A number of stakeholders felt that the TyresProgramme should have continued for five rather than three years.
Figure 6 shows that, overall, the WRAP Programme was effectivewith only two respondents stating that it was
not very effectiveand no stakeholders that it was not at all effective. This is a positive outcome for the Tyres
Programme.

It is important to note that although the responses received provided good and full feedback on the WRAP Tyres
Programme, only a relatively small number of stakeholders returned the questionnaires. From the responses it is
clear that there was an overall view that the programme had been effective, however these views do not
necessarily reflect the view of the whole industry. In order to obtain a more comprehensive view of the
Programme a response rate of at least 50% would be preferable.

Forecast of UK Markets for Waste Tyres
7.0 Used Tyre Arisings
There are a number of factors that are likely to affect the volumes of used tyre arisings within the UK. These key
factors include:
the growth/decline in road transport use in the UK;
improved durability of tyre materials; and
policy or legislative changes.
Generally it is predicted that volumes of used tyres are expected to rise as car ownership increases and as the
number of miles driven per vehicle year is growing. However, improved durability of tyres could potentially curb
this growth and the increased use of public transport, for example, in response to rising fuel prices and initiatives
to reduce carbon emissions, could mean that cars are being used less frequently resulting in longer tyre lifetimes.
In order to forecast future waste tyre arisings in the UK, ERM assumed that used tyre arisings would increase at
the same rate as traffic growth. Two different methodologies were used to predict the arisings of waste tyres inthe UK up to 2015. Both used baseline figures from the Department for Transport (DfT) and traffic growth rates
based on traffic trends. However, one scenario is based on historic data and the other on forecasts.
7.1 Growth Rate 1: DfT Future Forecast
The DfT forecast traffic growth rate up to 2025 used baseline data from 2003. These were the most recent
forecast figures published in 2007. These forecasts are split by cars, Light Goods Vehicles (LGVs) and Heavy
Goods Vehicles (HGVs). It is forecast that LGV traffic will increase most rapidly as it has generally increased in
line with GDP in past. Car traffic growth follows that of total traffic very closely due to the fact that cars make up
a high proportion of total traffic. HGV traffic has grown more slowly than car traffic.
In terms of used tyre arisings, ERM applied these percentage growth rates to DTI waste tyre arisings data for
2004. This was considered a more appropriate baseline year and provided more realistic arisings data when
compared to actual data from 2004, 2005 and 2006.
Table 2 below provides a summary of the percentage growth rates from the DfT forecast from 2003 to 2010 and
2015 retrospectively.

7.2 Growth Rate 2: 1.3% increase based on historic traffic growth
The DfT has reported on road traffic increases from 2001-2005. This provides details on increases in car, light
commercial vehicles and goods vehicles and an overall increase of all vehicle types. In order to forecast future
tyre arisings, ERM used the average of the total growth rates and assumed that tyre arisings would increase in
line with traffic growth.
This assumes a growth rate of tyre arisings of 1.3% per annum from 2007 to 2015.
Figure 7 below shows the difference between the two growth rates. It is clear that there is an insignificant
difference between them. For the future management route scenarios, ERM has used Growth Rate 1: DfT
Forecast.

Figure 8 shows the management routes of used tyres from 1998-2006 using data from the DTI. It is clear from
this that recycling increased dramatically from 2002 and is now more constant. It accounts for the highest
tonnage of tyres managed in the industry. Disposal of tyres to landfill has tapered off dramatically as the bans on
whole and shredded tyres came into force. Energy recovery and landfill engineering have both increased, with
the other management routes remaining fairly constant.

8.0 Factors affecting End Markets
8.1 Past and Current End Markets
In the past a significant percentage (around 25%) of used tyres were disposed of via landfill. The ban on the
disposal of whole tyres (except bicycle tyres and tyres with a diameter greater than 1.4m) to landfill came into
force in 2003, with shredded tyres being banned from 2006. This has resulted in the tyre recovery industry
having to accommodate the large number of tyres that were originally sent to landfill. There were concerns that
this ban would result in more tyres being illegally dumped and stockpiled due to insufficient end-markets for
these tyres.
The increasing use of tyres as a fuel in cement kilns has helped to deal with the excess of tyres that were
previously sent to landfill. The burning of tyres in cement kilns was first trialled in the mid 1990s. Along with a
number of other processes such as landfill engineering, this has helped provide a solution to the large number of
waste tyres arising in the market.
The use of shredded tyres as a leachate drainage layer in landfill sites has also taken off in recent years, and
accounts for significant volumes that would previously have been disposed to landfill.
Until approximately 10 years ago, retreading was a preferred means of reusing passenger car tyre casings as it
effectively doubled the life of a tyre. However, the growth of the budget market for new tyres, particularlyimports from areas such as the Far East, made the process less economically viable. Consumer perceptions

UKs Used Tyre Market up to 2015 14

regarding the safety of car retreads have also resulted in a reduced demand for these tyres. However there is a
strong market in the use of retreads in truck tyres. This is mainly due to the cost benefits of retreading these
tyres. For example, road hauliers almost invariably cost the use of these tyres per kilometre of road usage or per
millimetre of tread2.
The material recycling of used tyres was less prevalent in the past but has increased considerably over the last
few years and now is the largest management route for dealing with used tyres. In 1999 20% of used tyres
were recycled, and by 2005 33% of used tyres were recycled. The use of waste tyre granulate in products such
as sports and playground surfaces has become widespread with the increasing market demand resulting in thedevelopment of these industries.
8.2 Factors affecting End Markets
There are a number of factors likely to affect the future end markets of used tyres. The majority of these factors
have affected end markets in the past. This includes the introduction of new technologies, changes in global
market conditions and demand for different applications. These factors are listed below.
Possible environmental policy and legislative controls (eg ban on landfilling, cement kilns authorisations,
energy from waste incentives);
New emerging technologies which provide alternative outlets to traditional management routes;
Acceptance of waste tyre crumb as alternative materials in building and construction projects;
Global market conditions which affect new/retread tyre sales;
Restrictions on stockpiling;
Reduced demand for tyres in landfill engineering applications in the longer term;
Increased demand for tyres in flood defence applications;
Increased use of public transport;
Energy costs;
Longer tyre life/lighter tyres; and
Possible uptake of pyrolysis and cryogenic reprocessing facilities.
8.3 Stakeholder Feedback on Future Markets
According to the stakeholder responses, the greatest impact on future management routes for used tyres is likely
to be environmental policy and legislative controls. The banning of tyres and shredded tyres from landfill has
meant that alternative markets have needed to be found to dispose of used tyres. Climate change policies are
also likely to have an impact on future markets. The carbon footprint of products is clearly on the environmental
agenda and therefore processes that result in high carbon dioxide (CO2) reduction such as retreading and
recycling are likely to be considered more favourably.
Other factors that stakeholders felt were likely to have an impact on future management routes include:
uses of tyres in flood defence there is likely to be a greater need for flood defence applications particularly
with the recent weather patterns in the UK;
the cost of energy;
the reduced demand for tyres in landfill applications;
increased use of public transport and longer life or lighter tyres could reduce the arisings of used tyres;
new and emerging technologies;
acceptance of rubber crumb for use in construction, road resurfacing; and
greater acceptance of retreading and that recycling tyre rubber can be used in the manufacture of new tyres.

In terms of new and emerging management routes for used tyres, stakeholders suggested a number of routes
they felt were likely to be used for tyre disposal and recovery in the future. These were:
Sonic, thermal and electrical insulation;
Protective coatings;
Wear, corrosion and impact resistance;
More specific applications for granulate and crumb;
Potential for use in electric arc steel furnaces - this depends on the way steel making develops in the UK;Water jetting;
South Wales cryogenic plant;
More products from tyre reprocessing;
Pyrolysis;
Partial devulcanisation; and
Increased use of recycled rubber in new tyres
8.4 Future End Markets
Factors such as legislative controls and environmental policy (as mentioned in Section 8.2 above) will remain the
factor likely to have the greatest impact on management routes/end markets as these are often mandatory and
therefore the industry are obliged to react to the new requirements. According to BERR however the likelihood of
any new measures in this area in the immediate future may be limited.
Within the cement kiln industry, burning of tyres is dependent on the permits issued by the EA, as well as being
limited by kiln technology. If permits are granted, the cement kilns are allowed to replace a percentage of fuel
with tyres. If regulations change and tyres are no longer accepted at these plants, alternative markets will need
to be found. However, in ERMs view this is unlikely to occur. Other issues impacting on the number of tyres
being sent to cement kilns include the competition from other waste materials which are seen as possible fuel
sources such as RDF. The availability of other materials can impact on gates fees charged by the cement kilns
and fluctuating gate fees can result in cement kilns proving to be less popular options.
However, the increased costs of fossil fuels could result in an increased demand for tyres in cement kilns as they
are a cheaper and more environmentally beneficial fuel. Assessing the carbon impacts of industrial operations,
products and services are increasingly being discussed with a view to reducing these impacts. The cement-
making process gives off carbon dioxide, so finding other methods of reducing emissions is important in this
industry, particularly for European cement companies which are regulated under the EU emissions trading
scheme. Alternative fuels are therefore encouraged in order to reduce the carbon footprint and emissions from
the plant. It is likely that tyres will continue to be used in cement kilns in the foreseeable future. Tyres and
other waste fuels such as RDF provide a more environmentally beneficial fuel as they are burning a waste rather
than a virgin material.
Weather conditions in the UK could potentially impact on the outlets for waste tyres as it may be possible to
utilise baled tyres in flood defence schemes. Approximately 100 scrap tyres are used in the production of onebale. However, in ERMs view this is presently unlikely to result in the diversion of significant tonnages of waste
tyres.
New and emerging technologies such as cryogenic reprocessing facilities may open up new end markets and
result in a higher demand for tyres to in these areas. The first plant opened in Neath Port Talbot in South Wales
in 2007 and predicts that 70% of the rubber crumb will be used to turn into artificial sports surfaces. New
technologies such as these will inevitably have an impact on the industry creating new outlets for the recovered
material from used tyres. As demand increases in these areas, it could impact on other management routes.
Landfill engineering for example is likely to decline in the longer term due the general decline in the use and
favourability of landfills. However, if there is a wider acceptance among operators that shredded tyres are a
good material to use for leachate drainage layers, then the market in this area is likely to remain stable.
Although the use of landfills to dispose of waste are expected to decline in the future, there is likely to be a
continuing need for landfill disposal space for in the immediate future. Processes such as cryogenics could
potentially provide the additional capacity required to deal with the excess of tyres as other management routes

UKs Used Tyre Market up to 2015 16
-
8/14/2019 Uk Waste Tyre Data
19/57
diminish. However, these processes are only viable if a market exists for their end products. For example, if the
demand for rubber in sports surfaces declines the demand for tyres in processes such as cryogenics will also
decrease.
The use of rubberised asphalt is becoming increasingly popular as the shock-absorbing properties of rubber
provide an added safety factor and the material provides a more durable road surface and decreases noise
pollution. If the use of tyres in roads increases it could result in a significant number of tyres being recycled and
therefore increase demand in this area.
Economic drivers will also impact on the future markets and end management routes for used tyres. If higher
value markets emerge or become more prevalent lower value markets will be displaced. The used tyre market is
demand driven and management routes will react to this demand. If higher value markets such as the cement
kiln sector increase their demand for and reliance on tyres as a feedstock, the lower value markets such as
landfill engineering are likely to suffer.
9.0 Forecasting Used Tyre Arisings
WRAP commissioned Oakdene Hollins to provide a study of the UK Used Tyre Market in 2004. This report sought
to provide arisings and recovery/disposal data for 2004 and to compare these findings with the Used Tyre
Working Group (UTWG) figures. Various assumptions were made and detailed modelling was undertaken to
arrive at figures that could be used with confidence. Oakdene Hollins also prepared a report on Used TyreMaterial Flows and Market Analysis. The report suggested a number of change scenarios in the UK and their
potential effects on the tyre market.
In order to develop predictions for future waste tyre end markets, ERM developed a spreadsheet model. ERMs
forecasts of tyre arisings are based on the Used Tyre Working Group/DTI (now BERR) figures. Oakdene Hollins
figures were considered, but it was considered that, for consistency, it would be more appropriate to use data
from one source from 1998-2006. It is important to note that data for 2006 are indicative and have not yet been
finalised.
The stakeholder questionnaire asked respondents to provide forecasts of what they considered likely to happen
with the management routes of tyres in the future. ERM used these responses and our own knowledge of the
tyre industry to produce four different scenarios to illustrate how used tyres could potentially be disposed of in
the future by showing the tonnages and percentage increases/decreases of tyres likely to be sent to each
management route.
9.1 Scenario Forecasts
ERM developed four different scenarios based on responses from stakeholders and our own knowledge of the
industry. All the scenarios are based on arisings data using the DfT forecast growth rate (see Section 7.1).
The source data provided by the DTI is presented in Table 3 below.

from year to year and it is impossible to predict what is likely to happen in the future. Therefore, for our
purposes in forecasting future tonnages this fate has been omitted.
Figure 9 below shows the four scenarios and the difference between the six available management routes. These
will be described in more detail in the following sections.

Figure 9A Comparison of the Four Scenarios
-
8/14/2019 Uk Waste Tyre Data
22/57
9.1.1 Scenario 1In this scenario reuse, retreading, energy recovery and exports remain constant. The only management routes
that change are recycling and landfill engineering. Market demand for tyres, particularly for use in road surfaces,
will result in an increased need for used tyres to be recycled. Other factors likely to increase the number of tyres
being recycled include sports surfaces although this is unlikely to result in such a significant increase in tonnages
in this area. Landfill engineering is predicted to decrease as landfill in general becomes less favourable.
Table 4 shows the proportion of waste being managed by each treatment/disposal route used in this scenario.These growth rates were applied to the tonnages for specific years using the DfT arisings forecast (as mentioned
in Section 9.1). For example, the 2009 growth rate was applied to the years 2007 to 2009, the 2012 growth rate
was applied to 2010 to 2012 and the 2015 growth rate was applied to 2013 to 2015.

Exports 4 4 4
TOTAL 100 100 100
9.1.2 Scenario 2In this scenario a number of the management routes change. Both recycling and energy recovery are predicted
to increase. Recycling, as mentioned above, will continue to rise due to new and emerging technologies resulting
in an increased demand for tyres in this area. In scenario 2 it is believed to grow more rapidly than in Scenario 1.
Energy recovery is predicted to increase slightly due to increased fossil fuel costs resulting in the industry looking
for alternatives to fuel their plants. Reuse is also predicted to increase as demand grows for bales in flooddefence. Both landfill engineering and the export market are predicted to decrease. Landfill engineering will
decrease more rapidly than in Scenario 1 due to landfills themselves declining in popularity. The export industry
could potentially decline as other countries tighten up regulations in this area. Retreading will remain constant as
there will always be a market for this form of reuse in the truck tyre industry.
Table 5 below shows the proportion of waste being managed by each treatment/disposal route in this scenario.

9.1.3 Scenario 3In this scenario, the greatest difference is that energy recovery is predicted to decline. From discussions with
industry it is felt that this is unlikely, however it is included here as a scenario to show what could potentiallyhappen if cement kilns began to use alternative fuels other than tyres, or if gate fees increased to the extent that

it would discourage tyre collectors from taking tyres to these plants. In this instance, the tyres that would have
been used in energy recovery are now being either recycled or reused meaning that these management route
tonnages increase. It was also predicted that the retread and export industry would also decline with landfill
engineering remaining constant.

9.1.4 Scenario 4In Scenario 4 reuse and retreading remain constant. It is felt that these management routes will fluctuate theleast within the industry and that they will increase in line with arisings. Recycling and energy recovery are
predicted to increase as other management routes begin to decline. As mentioned previously, new and emerging
technologies will increase demand in tyres in recycling and as fossil fuel costs increase alternatives will be sought
to as a fuel for cement kilns. Landfill engineering will gradually decline as landfill generally becomes less
favourable and exports are predicted to decline as legislation in other countries becomes tighter.

The following figures show the four different scenarios by management route and the potential variations that
could occur within the industry by 2015. The figures also show an estimated average for each of the four
management routes indicated as a straight line trend over the period to 2015.

10.0 The Preferred Scenario
ERM provided WRAP with a simple forecast model in which users can alter the percentages of used tyres being
sent to each management route in order to see what impact this will have on the other sectors within the
industry. Figure 16 below provides an example of the output of this model and shows the preferred scenario
used for this model.
This model is based on Scenario 4. It was felt that this scenario provided the best estimate as to what was likelyto happen to used tyre management routes in the future. The choice of this scenario was based on information
provided by key stakeholders and from our own knowledge of the industry. ERM also looked at the best fit lines
on the figures above and it was clear that Scenario 4 had the closest fit to this line and therefore it could be
considered to be the best scenario using this method.
In ERMs view Scenario 4 presents a realistic picture of the way in which the future management routes of used
tyres might look. The reasonings behind this will be discussed in more depth in Section 11 however Table 8
below provides a brief summary.
Table 8 Summary of the Likely Future M anagement Routes of Used Tyres
Management Route Decrease/
Increase?
Further Comments/Reasons
Reuse Remain constant There will always be a market for this management route.
It has the potential to increase if processes such as baling
become more prominent in, for example, flood defence
schemes. However, in ERMs view it will increase
proportionately to the increase in used tyre arisings.
Retreading Remain constant This will remain constant although it is predicted to increase
slightly in terms of truck tyres, with car tyre retreading
decreasing over time. Overall, therefore, the tonnage of
tyres being sent to this management route will remain
relatively stable.
Recycling Increase Applications such as sports surfaces and horticultural uses
are likely to grow and there is also a potential market
increase for rubber in construction and for use in roads.
Landfill engineering Decrease This will decrease as landfill void space declines and as
more environmentally sound and efficient technologies for
dealing with waste are being introduced.
Energy recovery Increase This is likely to continue to grow as the cost of fossil fuels
increase and as alternative, more environmentally sound
fuels are required in cement kilns.
Exports Decrease The market is difficult to predict, however as regulations in
other countries become tighter it is likely to decline.

Key Conclusions11.0 Conclusions and ERM Forecasts
11.1 Reuse
It is predicted that the reuse of used tyres will remain fairly constant and that there will always be a market forthese tyres. Reuse does have the potential to increase if processes such as baling become more prominent
through uses such as flood defence schemes. With predicted changes to weather patterns in the UK, it is likely
that improved flood defence schemes will be required and that the demand for such products will remain.
However, flood defence scheme are unlikely to offer large volume markets in themselves.
Emerging technologies such as surface repolymerisation could also result in an increase in the reuse and
retreading market. This process enables crumb rubber from waste tyres to be incorporated into retread
compounds at much higher rates than before.
11.2 Retreading
Overall tonnage of tyres sent for retreading is likely to remain relatively constant although there will be a slight
increase in retreading of truck tyres, accompanied by a decrease in car tyre retreading.
Until recently retreading was a preferred means of reusing used car tyres as it effectively doubled the life of a
tyre. Despite the improved quality of retreads, there has been a continuing decline in the passenger car retread
market. Imports have also made the process less economically viable as cheaper new car tyres have been
introduced into the market. Consumer perceptions regarding the safety of car retreads has also resulted in a
reduced demand for these tyres. However there is a strong market in the use of retreads for trucks. This is
mainly due to the cost benefits of retreading these tyres. For example, businesses sometimes cost the use of
these tyres per kilometre of road usage or per millimetre of tread3. It is therefore possible to conclude that the
truck tyre retread market will remain strong but it is unlikely that car tyre retreading will be a significant
management route for the reuse of these tyres.
11.3 Recycling
The recycling of tyres is predicted to increase. Applications such as sports surfaces and horticultural uses are
likely to grow and there is also a potential market increase for rubber in construction. A cryogenics facility
opened in 2007 (which is expected to process 30,000 tpa of tyres) and around 70% of this crumb will be used in
sports surfacing. Aquablast (water jetting facility) is potentially opening in 2008 which uses high pressure water
jets to remove tyre rubber from the reinforcing steel in earthmover tyres. The introduction of these technologies
could potentially result in more demand for used tyres to feed into these processes; however, these are only
viable if there is a market for the output. If, for example, the demand for rubber in sports surfaces declines the
demand for tyres in processes such as cryogenics will also decrease.
The use of rubberised asphalt is becoming increasingly popular. The shock-absorbing properties of rubber
provide an added safety factor and the material provides a more durable road surface and decreases noisepollution. Trials have been carried out (funded by WRAP) in order to test these surfaces as they have the
potential to use high tonnages of used tyres. If the use of tyres in roads increases it could result in a significant
number of tyres being recycled and therefore increase demand in this area.
This management route encompasses numerous different processes for the recycling of used tyres and also
provides the largest management route, with approximately 33% of used tyres being processed via this route.
This and the fact that the recycling of tyres provides one of the best means of dealing with the arisings means
that the development of new technologies is likely to continue in this area.

11.4 Landfill Engineering
The use of tyres in landfill engineering is likely to remain stable for the next few years. It does have the potential
to tail off in long term as the use of landfill generally declines. As sites for landfills are harder to acquire, void
space declines and new, more environmentally sound technologies are introduced for dealing with waste the
overall use of landfills will decrease. This will clearly result in reduced demand for tyre shred in landfill
engineering and this market is likely to decline in the future. However, there is currently still demand for
shredded tyres as an engineering material and therefore it is likely to remain relatively stable in the short term.
11.5 Energy Recovery
In terms of energy recovery, it is felt that the use of tyres in cement kilns is likely to increase. However, there is
a risk that this use of tyres might be banned through new regulations, or that gate fees will increase and this
would create huge implications to the tyre industry, with a potential 20% of used tyres having to find other
means of disposal. This could potentially be picked up via the reuse and recycling routes such as baling.
The increased costs of fossil fuels could result in an increased demand for tyres in cement kilns as they are a
cheaper and more environmentally beneficial fuel. Assessing the carbon impacts of industrial operations,
products and services are increasingly being discussed with a view to reducing these impacts. The cement-
making process gives off carbon dioxide, so finding other methods of reducing emissions is important in this
industry, particularly for European cement companies which are regulated under the EU emissions tradingscheme. Alternative fuels are therefore encouraged in order to reduce the carbon footprint and emissions from
the plant. It is likely that tyres will continue to be used in cement kilns for the foreseeable future.
11.6 Landfill
From July 2006 all tyres (except for bicycle tyres and tyres with a diameter greater than 1.4m) have been banned
from landfill apart from those being used for landfill engineering purposes. There is the potential for a very small
percentage of tyres still to end up in landfill.
As this is now such a minor route, we have not provided any forecast for the number of tyres likely to be sent to
landfill in the future.
11.7 Exports
The export of used tyres is quite difficult to forecast. However, it is likely to decrease. The Oakdene Hollins
study Used Tyres Material Flows and Market Analysis Market Disruption Planningstated that as importing
countries are tightening road traffic legislation and/or restricting imports while they deal with their own tyre
surpluses it is likely that the export industry will decline. Imports in to developing countries can also be restricted
to help protect local industries.
The majority of stakeholders who provided forecasts of future used tyre arisings stated that the export industry
would either decline or remain constant; none felt that it was likely to increase which mirrored the view of
Oakdene Hollins. ERM believes that it is difficult to predict what will to happen to this management route, but is
also of the view that it is likely to decline as other management routes become stronger and as legislation in
other countries becomes tighter.

PART 2 - The Likely Future Management of Waste Tyres
ERM has also been asked to develop a series of possible projections for the future handling of used tyres up until
2015 and factors that can impact on:
the volumes of used tyre arisings; and
the different methods of managing used tyres.
Factors affecting the volumes of used tyre arisings include policy or legislative changes affecting growth/decline
in road transport use in the UK, improved durability of tyre materials etc.
Factors affecting the availability of end markets which handle used tyres include:
environmental policy and legislative controls (eg the banning of tyres from landfill, cement kiln authorisations,
energy-from-waste incentives);
new emerging technologies which provide alternative outlets to traditional management routes;
acceptance of waste tyre crumb as alternative materials in building and construction projects;
global market conditions which affect new/retread tyre sales;
restrictions on stockpiling;
reduced demand for tyres in landfill engineering applications;
increased demand for tyres in flood defence applications;
uptake of pyrolysis and cryogenic reprocessing facilities etc.
The main objective of this part of the stakeholder consultation is to seek your views on the likely future
management of waste tyres (see question below)
