Sorting out recycling: new separation method for plastics
2019-7-25 A new method for separating different types of waste plastic has been developed by Turkish researchers. The ‘flotation’ method recovers PVC and PET, among the most difficult plastics to separate from each other. It could help increase the amount of plastic waste that can be recycled and ease pressure on bulging landfill sites.
