There’s one area of plastics not mentioned, perhaps because they are not ‘micro’ enough, but polystyrene (bean bags, insulation, protective packaging for a myriad of products, garden/potting mix) is a huge problem. It is not unusual to see a broken piece of ‘packaging’ lying in the road and being crushed and broken down to the individual ‘beads’ by passing traffic which quite easily get washed into our water ways. I recently bought a large carpentry tool that came packed within a very large polystyrene protective case within a cardboard box. There are some companies that use recycled cardboard as the protective casing and this is easily recycled again. Perhaps all companies should be encouraged to use cardboard instead of the almost impossible to recycle polystyrene!
