Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, which UK recycling plants are equipped to accept and recycle (a) PET plastic waste, (b) HDPE waste, (c) polyvinyl chloride waste, (d) polypropeline waste, (e) polystyrene waste and (f) low density polyethylene waste.

Defra does not hold this information. A list of accredited plastic reprocessors is available on the National Packaging Waste Database at the link below, but this does not provide details of the type of plastics dealt with by a site:
