Plastic pollution is at the top of the global public agenda nowadays, while the most relevant solution to this issue is a well-designed system for the plastic collection, processing and disposal. R&D investments, regulatory measures, educational projects all around the world are aimed at implementing this model. Harnessing the potential of plastic recycling is in the focus of the petrochemical industry as well. What are the prospects of plastic waste management? What are the differences between processing technologies? Can biopolymers become a universal solution to the problem?
