The most popular biodegradable plastics synthesize

  • Detail

Bernard Ollivier, director of the Environmental Microbiology Research Office of the "Development Institute" in Marseille, France, explained: "the first step of the process developed by Yannick Combet Blanc is to turn disaccharides or glucose and fructose in beets into lactic acid through bacterial fermentation." The research team led by Bernard Olivier extracted two strains with good characteristics. One is the patented Bacillus thermoamlovorans. In the thermal environment, the needle hole in the G oil delivery valve is blocked (55 ℃) and can produce a large amount of lactic acid, which is of particular interest to industrial manufacturers. The second strain is currently under patent protection

Michel vert, director researcher of the University of Montpellier in charge of the final process stage of the research program, said: "after sugar is changed into lactic acid, lactic acid molecules are polymerized into lactic acid polybasic acid through chemical means (that is to say," the performance of this kind of new thermoplastic is better and longer than that of commercial plastics such as ABS) To form plastic raw materials. This kind of plastic can be biodegradable in the natural environment and can be biologically absorbed. " This production process is currently under patent protection. Bernardolivier stressed: "the advantage of this method is that it can use the waste liquid from industrial sugar making process to produce plastics.
