German company Danone develops polylactic acid degradable plastics and packaging products

German Danone company recently developed polylactic acid biodegradable plastics and packaging products, its physical and mechanical properties and general polystyrene, polypropylene similar, and has good moisture, oil and seal. The material has stable performance at normal temperature and can be quickly biodegraded at a temperature higher than 550C or in an environment rich in oxygen and microorganisms. First, the polylactic acid is hydrolyzed into lactic acid monomers, and then decomposed into carbon dioxide and water under the action of microorganisms. According to an on-site test, a cup made from polylactic acid can be completely biodegraded in 2 months under certain environmental conditions. It is an ideal environment-friendly product, but due to the excessively high price, further research is needed to reduce costs, which is conducive to rapid promotion. .
