There were around 30 million motor vehicles in use within the UK in 2002. Every year, approximately 2 million new vehicles are registered and a similar number are scrapped.The average lifespan of a car is 13.5 years and in 2000, just over 2 million cars and vans reached the end of their useful lives, either because of old age or due to accident.

The composition of a typical car has changed substantially in recent years. For example, ferrous metal content has decreased significantly as lighter, more fuel-efficient materials such as plastics are incorporated into vehicle design. An analysis of vehicle manufacturer data for around seventy popular 1998 car models shows the following breakdown of materials (by weight).

Over 50 million tyres (just over 480,000 tonnes) were scrapped in the UK in 2001 and around 80,000 tonnes was disposed of in landfill.

Tyres consist mainly of steel, rubber compound and textiles (often in the form of cotton). The typical composition of tyre rubber is as follows:

Why bother?

 top of page

The quantity of used vehicles that are not resold equates to over 2 million tonnes of material to be recovered or disposed of. 1.85 million cars are recycled every year in the UK, and approximately 80% of waste automotive materials (mainly metal) are recycled, with the remainder going to landfill. As car ownership continues to increase it is important that the proportion of each end-of-life vehicle (ELV) being recycled is maximised, so that the environmental impact is reduced.

It is estimated that up to 50% of the 20,000 tonnes of oil removed from vehicles by motorists is handled improperly. If oil finds its way into sewers and water courses it can cause significant contamination -

one litre of waste oil is sufficient to contaminate one million litres of water and oil poured onto the ground will affect soil fertility.

When disposed of in landfill sites, tyres in large volumes can cause instability by rising to the surface of the site, affecting its long term settlement and therefore posing problems for future use and land reclamation. Rubber materials contain proportions of organic chemicals and little is known about the long-term leaching effects of these materials.

It is estimated that around 13 million stockpiled cars are currently being held in dumps with the number of tyres being illegally dumped increasing. It is thought that higher charges levied on producers for legal disposal, coupled with generation of more waste tyres because of stringent tread requirements are key causes of this. Recently, problems have arisen with collectors who are paid to collect and remove tyres for recycling purposes and who then merely dump or store the tyres with no intention of recycling them. Illegal disposal of tyres is seen as a serious offence with possible imprisonment and unlimited fines.

 

How's, what's and where's of recycling vehicles and tyres

 top of page

The reuse of parts and the reclamation of materials from motor vehicles is not a new industry. Metal parts in particular have for a long time had a value, either in terms of reuse or recycling. Nowadays there are many parts that can be recycled, from the oil and its filter to plastic bumpers.

When a car reaches the end of its useful life it is usually sold to a vehicle dismantler. The dismantler will remove parts that can be sold for reuse, remove the potentially environmentally polluting materials such as operating fluids and batteries, and then sell the hulk on to a shredding operation. Shredders are high capacity hammer mills that break the hulk in to fist-sized parts. Ferrous metals are then removed by magnetic separation and non-ferrous metals are sorted both mechanically and by hand. The proportion of ELVs currently recycled is much greater than any other consumer product; even so, around 408,000 tonnes of remaining material is buried in landfill sites each year. This material is mainly made up of plastics, rubber, glass, dirt, carpet fibres and seat foam.

What you can do?

 

Recovery and disposal of individual components

Metals

Approximately 76% by weight of the average car is metal, most of which is comprised of sheet steel. The overall metal content of cars has declined rapidly during the past 20 years accompanied by an increase in the proportion of non-ferrous metals used in their manufacture, such as aluminium and magnesium. Currently about 98% of the metals in a car are recycled. These metals are recovered by the vehicle shredding industry and subsequently utilised by the steel industry and re-smelting plants.

Plastics

Plastics used in the car industry have risen considerably, where an average new car in 1984 contained 8.5% by weight of plastics a similar car today contains around 11%. Plastics are used for their distinctive qualities, such as impact and corrosion resistance, in addition to low weight and cost. Due to its lightweight properties, the use of plastics can lead to considerable energy savings, with a car weighing 1.3 tonnes without plastics consuming approximately an extra 1000 litres of fuel during its life compared to a car weighing 1.1 tonnes with plastic . Despite the relatively high recycling rate for ELVs, the proportion of plastics from ELVs being recycled is extremely low. One reason for this is the wide variety of polymer types used. Identification, by marking components at production or by improved sorting technologies, will be vital if the practice of recovering plastic parts is to become viable. One of the few plastic parts currently being recovered from ELVs is battery cases, accounting for 5,000 of the 14,000 tonnes of automotive plastics recycling in 1998. There is an estimated further 121,000 tonnes of automotive plastics which is currently landfilled.

The most common automotive plastics types are polypropylene (PP), polyethylene (PE), polyurethane (PU) and polyvinylchloride (PVC). PP accounts for approximately 41% of all car plastics (common in bumpers, wheel arch liners and dashboards), and like PE and PU (most common in seat foam) it is easily recycled. Viable markets for PP, PE and PU from non-automotive sources already exist.

PVC makes up about 12% of the plastics content of an average 1990s European car. PVC, by contrast, is relatively difficult to recycle, and there are currently no large-scale recycling schemes operating for post-consumer PVC. Alternative disposal methods such as incineration have raised a number of environmental concerns including dioxin emission during incineration and the use of phthalate plasticisers, which are thought to be disrupters of hormone systems. Nevertheless, this is likely to change due to proposals for a European Directive on the disposal of PVC. Car manufacturers are currently looking for alternatives to PVC.

Vehicle operating fluids

This is one of the areas of greatest concern regarding motor vehicles. Although the disposal of fluids from ELVs is a major issue, the effects of inappropriate treatment of fluids removed during servicing are also significant. Increasing amounts of engine oil are being recovered and recycled however less than a third of waste oil produced by the DIY motorist is recycled. Lubricating oil has the greatest pollution potential.

Much of the waste oil collected for recovery in the UK is processed (by removing excess water and filtering out particulates) and used as a fuel burnt in heavy industry and power stations. However, stricter emission limits and fuel quality controls resulting from environmental legislation could mean a reduction in the amount of waste oil used in this way. The preferred option for lubricating oils is re-refining for reuse as a base lubricant, although this doesn't currently occur on a large scale in the UK.

Waste oil from nearly 3 million car oil changes in Britain is not collected. If collected properly, this could meet the annual energy needs of 1.5 million people.

There are 1,500 Oil Recycling Bins in Britain for lubricating oil only. Call the Oil Care Campaign on 0800 66 33 66 or use the post code search on their website www.oilbankline.org.uk to find the location of you nearest oil bank.

When removed, oil filters can retain large amounts of oil and this may be discarded with the filter leading to further pollution. Vehicle dismantlers leave oil filters on the engines and they are recycled along with them. Oil can be recovered using special oil filter presses which squeeze out the oil and the remaining flattened metal filter can be recycled with other steel. Oil filter crushers are available for use on site at garages, although this is currently not common practice. Nevertheless, it is hoped that oil filter crushers will be increasingly introduced into civic amenity sites as an added service to the DIY car mechanic.

Catalytic Converters

Catalytic converters ('cats') have only been fitted as standard in new petrol injected-engine cars since 1992, so the business of their recovery is still developing. In the US, there is a well-established network of agents who collect the cats and a similar system is developing in the UK. The steel from the exhaust and the precious metals from the cat can be recovered when the cat is replaced. Platinum, rhodium and palladium can be recovered for reuse, either in new auto cats or for some other purpose, and as 68% of platinum and 90% of rhodium used in Western Europe go into the production of catalysts, this business is extremely viable. The ceramic casing is also recovered as a powder for refining.

Batteries

EC Directive 91/157/EEC requires the separate collection of certain batteries, including those containing more than 0.4% lead by weight, which includes vehicle lead acid batteries. There is a well-established system for the recovery of lead acid car batteries with many local authorities and garages having collection points. The recycling rate for car batteries is estimated to exceed 90%. However, a significant number of batteries are still not recovered and recycled (for example, many scrap cars still contain batteries when they are shredded). A revision of the existing battery legislation is currently being undertaken. EU proposals include a 70 - 100 % collection target for automotive lead acid batteries with a recycling target of 50 - 80%.

Secondary Restraint Systems

Secondary restraint systems used in vehicles consist of airbags and seat belt pre-tensioners. Air bags became standard components in UK-produced vehicles in 1993. Some air bags are only activated as a result of certain types of collisions, so occasionally the bag is undetonated and in the absence of manufacturers' deployment instructions, a strict procedure should be followed in order to disarm the bag safely. Air bags do not contain high value materials, so reclamation is not a viable option. In addition, because of the high product specifications and specialist installation procedures required to fulfil their safety purpose, reuse is not currently an option either.

Glass

In 1999, ELV arisings reached 1.8 million. With glass constituting approximately 3% of a vehicles weight, in excess of 55,000 tonnes of automotive scrap glass were theoretically available for recycling. This figure is likely to be increasing with the rise in ELVs. Currently, in the UK the majority of ELV glass is sent to landfill and only a small proportion is recycled.

There are two types of glass used in the auto industry, toughened and laminated. Toughened glass is easy to remove from vehicles after shattering. Laminated glass, however, doesn't shatter and will need to be removed manually, which is time-consuming. In addition, as the value of glass is relatively low (approximately £0.48 per ELV), it is currently not possible to recover the cost of removal glass.

Tyres

 top of page

Tyres account for around 3.5% of the weight of an average ELV, and as a controlled waste under the Environmental Protection Act 1990, a Duty of Care is placed upon waste producers to ensure that waste material is disposed of safely through registered carriers to licensed sites. According to the Used Tyre Working Group's 2001 survey 22% were recycled, 8.3% went to energy recovery, 9.9% were retreaded, 16% were reused and 3.3% were used in landfill engineering. The remainder (approximately 40%) will have been landfilled, stockpiled or illegally disposed of.

Tyre disposal options:

Waste prevention is a primary objective when looking for future developments in scrap tyre options. Ongoing research into improvements in tyre design and construction has resulted in the life expectancy of tyres continuing to lengthen.

The TIC has developed a 'Responsible Recycle Scheme'. The scheme is designed to ensure that the reuse and recycling of used tyres complies with legal requirements.

What does the law say?

 top of page

The European Union End-of Life Vehicles (ELV) Directive

The End-of-Life Vehicles Directive (2000/53/EC) came into force on 21 October 2000 and Member States should have enacted legislation to comply with the Directive by 21 April 2002. The Directive will require EU Member States (including the UK) to:

It also requires the 'de-pollution' of vehicles before being recycled. This involves extracting petrol, diesel, brake fluid, engine oil, antifreeze, batteries, airbags, mercury-bearing components and catalysts.

Improvements required

In a report reviewing industry performance during 2000, the Automotive Consortium on Recycling and Disposal (ACORD) stated that the total recovery rate for vehicles scrapped in the UK is currently 80% (69% materials recycled and 11% parts reused). The report also outlined some of the areas that will require improvements in order to meet the 85% recycling rate by 2006. These include:

Tyres

EU Landfill Directive

The Landfill Directive (1999/31/EC) became law in July 2001. This states that whole tyres must be banned from landfill by no later than 2003, and shredded tyres no later than 2006. Some UK landfills may however escape the ban until 2007 when they are brought under the new pollution prevention and control regime. Because thousands of landfills need permitting under the directive, the Environment Agency will phase this work over 2002-2007. For more information on ELV legislation see our legislation affecting waste and recycling information sheet available on Waste Online.

Waste Incineration Directive

This requires that cement kilns, which use tyres as a secondary fuel, must comply with more stringent air emission limits that currently apply to other types of facilities. New dry kilns have until 2006 to comply. Old wet kilns have until 2008. This may impact current operations and further development.

These changes in legislation will obviously place increased pressure on the industry to find alternative uses for scrap tyres, and government ministers have suggested that if the 100% recovery/recycling rate is not met, they may be forced to legislate for compliance.
