Polymer Degradation Requirements

There are:
1. Starch-degrading polymers break down the starch chains in the PE polymer chains with bacterial enzymes, breaking the polymer chains into small units, which in turn causes the entire mechanical strength of the PE to decrease and rapidly degrade.
2. Microbial degradation produced by bacteria The polymer is fermented by bacterial saccharification enzymes, and the linear polyester product (PHBV polymer) is degraded, and the plastics are degraded by bacteria in the soil and sludge ponds.
Dr. Lawrence Swanson of the American KE Association, New Jersey Institute of Technology, and Dr. Suny Byookhaven of New York State explored and developed techniques for adding starch and additives to PP and PE to degrade waste plastics in soft mud and seawater.
Germany has introduced PP and PE plastics that are biodegradable in water and liquids from Belland, South America.
Foreign experts generally believe that in an environment rich in oxygen and humidity, it can promote rapid biodegradation of plastics, such as degradation by anaerobic bacteria, but will produce methane gas.
