Not all plastics are recyclable. There are 4 types of
plastic which are commonly recycled:
• Polyethylene (PE) - both high
density and low-density polyethylene.
• Polypropylene (PP)
• Polystyrene (PS)
• Polyvinyl chloride (PVC)
A common problem with recycling
plastics is that plastics are often made up of more than one kind of polymer or
there may be some sort of fibre added to the plastic (a composite) to give
added strength. This can make recovery difficult.
