Technical Principle:
AdmPro® Anoxic Biodegradable Masterbatch is an organic additive made by incorporating anaerobic organic additives into traditional plastics. These additives initiate the biodegradation phase of plastics through chemical activities caused by bacteria, ultimately leaving only natural gases and bioenergy. Plastics containing AdmPro® Anoxic Biodegradable Masterbatch can undergo biodegradation via anaerobic digestion in landfills, supporting marine degradation and meeting standards in China, Europe, and North America.
AdmPro® Anoxic Biodegradable Masterbatch introduces plastic into an anaerobic environment suitable for microbial degradation through a series of chemical and biological processes (this process is called bioassimilation). It allows microorganisms to create a biofilm structure that penetrates the plastic. This biofilm forms only under anaerobic conditions, such as in landfills and deep-sea environments, expanding the molecular structure to provide more space for microorganisms and emitting chemical signals that attract other microorganisms to feed on the plastic, thus accelerating the biodegradation rate.
Anaerobic microbial degradation occurs continuously in nature but is relatively slow and often unnoticed. However, solid organic PE plastics with added AdmPro® Anoxic Biodegradable Masterbatch can significantly accelerate this process, allowing PE plastics to biodegrade at a much higher rate. The final products are carbon dioxide, biogas (methane), and humus (organic matter), which are identical to the byproducts of organic material biodegradation.
This degradable product supports European and American standards, landfill degradation, and marine degradation, complying with ISO 15985, EN ISO 15985, ASTM D5511, GB/T 33797-2017. It is a low-cost biodegradable material suitable for export.
