Germany has developed a new process for degradable plastics

The Leipzig-Halle Environmental Research Center in Germany recently announced that the center has studied the use of biogas and bacteria to make environmentally friendly and biodegradable plastics.
According to reports, the bacteria used by the research center is a single methane strain, which can metabolize methane and produce fine-grained polymeric polyhydroxybutyric acid in the body, which can be extracted into plastic. Polymeric polyhydroxybutyric acid is similar in physical properties to plastic products such as PE and PVC, but is easily biodegradable, and the final product has only water and carbon dioxide and does not pollute the environment. The center stated that the raw material needed to produce this kind of plastic is biogas produced from the fermentation of organic waste, and biogas contains 60% to 80% of methane. After 24 hours of cultivation in the reactor, the mono-alkanes that have been cultured can produce polyhydroxybutyric acid, which can produce 0.02 g/l. Wastewater, residues and heat can be recycled in the reaction. To save costs.
