What is WEEE?

What happens to WEEE?

When equipment arrives it is tested to see if it works or can be repaired

WEEE Recycling – case study

• Collect from local authorities, distribution centres, businesses and others

• Goods taken to site and tested.

• Reused, repaired or recycled depending on condition

• Only 2% waste, everything else is sold

• Training prisoners to recycle and repair

ELV Recycling – case study• Specialist high volume depollution equipment pre-treat vehicles

received directly from local authorities, insurance companies, and the public.

• Hazardous waste items are removed and any fluid leaks contained.

• Vehicle transferred to a covered depollution building removal of waste products for recycling.

• After the depollution, the vehicle enters vehicle crusher and the compressed bails are then sent to steel mills for recycling.
