Nylon, the durable and elastic material, is like other plastics made from chemicals found in fossil fuels. Biodegradable plastics based on biomass-derived compounds are attracting attention as an alternative to conventional plastics, and Osaka Metropolitan University scientists have now synthesized biodegradable nylon precursors.
Professor Yutaka Amao’s team at the Research Center for Artificial Photosynthesis previously reported on a method for producing raw materials for biodegradable plastics from biomass-derived compounds. A polyester-type biodegradable plastic could be formed by using L-lactic acid as the raw material for polylactic acid.
