A life-cycle look at plant-based plastics
Researchers have worked for decades to develop plant-based plastics, which are made from renewable feedstocks and in some cases have the potential to biodegrade. But the greenhouse gas emissions associated with the manufacture and disposal of such plastics can be higher than their petroleum-derived counterparts. So it’s not immediately obvious which plastic is the greenest choice. A new analysis of the complete life cycle of several kinds of plastic derived from different feedstocks offers . . .
