Core Concept: Bioplastics offer carbon-cutting advantages but are no panacea

摘要

For at least 20 years, a few companies looking to enhance their green credentials have been making products out of bioplastics—polymers derived from plants, wood chips, food waste, and other renewable materials instead of oil or natural gas. In principle, bioplastics can be a welcome alternative to the fossil fuel-based plastics that represent a growing environmental scourge across much of the globe. And with advances occurring at a rapid pace, bioplastics may yet fulfill that promise.
