A company called Metabolix, based in Cambridge (MA), has been working on a technology to genetically engineer plants such as switchgrass to create a biodegradable polymer that can be extracted directly from the plant.
The research is focused on a polymer called polyhydroxybutyrate (PHB), which is part of the polyhydroxyalkanoate polymer (PHA) family of biopolymers that Metabolix already supplies to plastics manufacturers. The new plant-based process is potentially cheaper and requires less equipment, Metabolix says.
