Panel Discussion: Chemical wastes – how to close the loop?
End-of-life chemical materials such as plastics and mixed municipal solids waste have been traditionally regarded as valueless rubbish to be disposed of at minimum cost. This perception is rapidly changing, and these wastes are increasingly seen as a low-cost resource for chemical synthesis or energy generation. This leaves the question about the best use of these materials. Should we seek full closure of the loop for new chemical production or prioritize lower-cost alternatives that can be implemented immediately?
