Polylactide and biodegradable plastics
The mechanisms, methods and conditions necessary for degradation polylactide acid (PLA), as a base to obtain biodegradable polymer materials, especially their microbiological and chemical destruction are discussed in the article. The real picture of PLA destruction under the influence of external factors, including bacteria in compost and other substances, is quite complex and cannot be reduced to the breakdown of macromolecules into monomer links. Examples of foreign-made bioplastics that use various fillers to give polymers the ability to biodegrade and break down into monomers are given. In Russia, there are no domestic industrial production of biodegradable plastics based on polylactide. For the organization of polylactide manufacture modern large-tonnage production of lactic acid as a raw material are necessary. Renewable raw materials and technologies for producing lactic acid are available in Russia.
