That could transform the economics of making biodegradable polymers. Metabolix already sells such a polymer, but it’s produced by bacteria that feed on plant sugars in expensive fermenters. A plant-based process, which could use crops grown on marginal lands, would require less equipment.
Metabolix estimates that it could ultimately sell its plant-based polymers at less than half today’s prices. Whereas today’s end products are niche items like biodegradable plastic shopping bags, more widely used types of products and packaging could then become economical.
