UK Situation ELVs
10-12 million End of Life Vehicles (ELVs)
annually in the EU
Approximately 2 million ELVs in the UK
500,000 tonnes of non-metallic waste landfilled
Reduction by 40 (by mass) by 2006, 80 by 2015
Challenges to both automotive and recycling
industries
Identification and separation of specific
components for recycling
4
UK Shredders
Metals recycling industry vehicles, white goods
etc.
Shredding machines up to 200 tonnes/hr
fragments to size of a tennis ball
35 shredders in the UK
5
Metal Separation Shredder Residue
Between 70-74 ferrous metal removed by
electromagnets
Typically 95 of the metallic component is
recovered (ELV)
Air classification 20-25 removal of feedstock
fluff
6
ELV Directive Recovery/Recycling
9 plastic by weight in an average car
Valuable products stability and quality
1 Plastic
2 Polyurethane foam
3 Metal
4 Wire
7
Research at the University of Brighton
Separation of plastics from shredder residue
Separation of different polymer resins
Reprocessing of plastics into clean streams
Production of materials from 100 shredder
residue plastic
8
Simple Approach
Shredded material
Trommel into size fractions
Air classification foam
Density floatation plastics
Magnetic properties metal and wire
9
Shredder Residue Composition
Heterogeneous nature that continually varies
Plastic 90 gt8mm
Foam 95 gt8mm
10
Plastic Recycling
Need to increase recycling rate of ELVs
Predominant plastics are thermoplastic
polyolefins TPOs
Simple density floatation low cost and ease
Quantity and consistency market values
11
Hand-picked Plastic Experiment
Plastics picked from shredder residue gt100 mm and
100 10 mm sizes
Infrared spectroscopy to separate TPO plastics
Density-floatation separation
Washing and drying of plastic
Reprocessing and testing

Recycled Plastic into Automotive Products
Manual recycling different resins
Testing of sample specimens
Towards the voluntary 25 recycled plastic content
Other automotive products possible high-end
products
