'''[[w:Polyvinyl chloride]]''' ('''PVC''') is not accepted in normal consumer plastics recycling bins. But industrial PVC waste may be reprocessed. | |||
'''[[w:Polyvinyl chloride#Sustainability|Wikipedia on sustainability of PVC]]''' states that recycled PVC is broken down into small chips, impurities removed, and the product refined to make pure white PVC. It can be recycled roughly '''seven times''' and has a lifespan of around '''140 years'''. | |||
Another method is the '''[[w:VinyLoop]]''', a proprietary physical plastic recycling process for polyvinyl chloride (PVC). It is based on dissolution in order to separate PVC from other materials or impurities. The solvent is in a closed loop, hence the name. | |||

'''[[w:Low-density polyethylene]]''' ('''LDPE''') is the material that most [[w:plastic bag]]s are made of. The [[w:Plastic_bag#Environmental_issues|Wikipedia article on plastic bags, section "Environmental issues"]] states that many recycling plants don't process LDPE. | |||

[[File:Symbol Resin Code 6 PS.svg|100px|6-PS]] | |||
'''[[w:Polystyrene]]''' ('''PS''') | |||
[[w:Polystyrene#Recycling|Wikipedia on Polystyrene recycling]] states that it is generally not accepted in [[w:curbside collection]] due to the lack of recycling companies incentives to invest in compactors. An exception is [[Germany]] where PS is collected due to the packaging law (Verpackungsverordnung) that requires manufacturers to take responsibility for recycling or disposing of any packaging material they sell. | |||
