Biodegradable tableware, environmental protection and safety

  • 2022-07-19

Biodegradable tableware is produced by fermentation from renewable resources such as corn, potato and crop straw, and is further purified and polymerized to produce high-purity polylactic acid as raw material.

Polylactic acid (PLA) is a representative of completely biodegradable new bio based materials. It is a biodegradable environmental friendly polymer material with high cost performance at present. Compared with traditional petroleum based materials, polylactic acid can reduce about 3 tons of carbon dioxide per ton. This is because polylactic acid has good biodegradability. It is completely degraded by microorganisms and finally produces carbon dioxide and water. Compared with ordinary plastics, which are incinerated, a large number of greenhouse gases are discharged into the air. The carbon emission of polylactic acid from raw materials to polymer production is about 1/3 of that of general plastic polyethylene.

These degradable tableware do not produce toxic and harmful substances in the process of use and biodegradation, and have certain bacterial resistance, flame retardancy and UV resistance, which can be described as healthy, environmental protection and safety.
