Production method of Biodegradable Straw

Renewable plant resources (cassava, corn and other crops) are used to extract starch. The starch material is saccharified to obtain glucose, which is then metabolized and fermented by bacteria to produce high-purity lactic acid, and then high-molecular-weight polymerized lactic acid is obtained through synthetic methods. Afterwards, it is processed and formed into various biodegradable straws with good performance.

The PLA degradation straw has good biodegradability, degrades to produce CO2 and H2O, does not cause pollution to the environment, and can meet the needs of industrial composting. The straw extruded at high temperature has good heat resistance and good solvent resistance. Its smoothness, light transmittance, and hand feel can replace petroleum-based products. The physical and chemical indicators of the product can meet the food safety requirements of various places. Require. Therefore, it has a wide range of applications and can basically meet the needs of most beverages on the market.

It is believed that in the future, with the technological development of degradable plastics and the improvement of its non-degradable plastic recycling mechanism, the problem of environmental pollution by plastic waste can be resolved by mankind.
