In October 2019, the Greenpeace “False Solutions Report: Throwing away the future” incorrectly classifies solvent-based purification (dissolution) as chemical recycling for plastic waste.
They follow/copy uncritically the expertise of Zero Waste Europe’s study “Eldorado of Chemical Recycling” and both miss an opportunity, offered by a technology that leaves the polymer intact... for what they normally have a preference for.
Solvent-based purification and mechanical recycling are technologies based on physical processes and both leave the polymers intact so that they can be re-used and stay in the "cycle".
