A PROCESS METHOD FOR PREPARATION OF BIO-RENEWABLE, BIODEGRADABLE, BIOCOMPOSTABLE AND BIODIGESTIBLE AGRICULTURAL VEGETAL WASTE-PEPTIDE-POLYOLEFIN POLYMER COMPOSITE

摘要

A method for preparation of bio-renewable, biodegradable, biocompostable and biodigestible agricultural vegetal waste-peptide-polyolefin polymer composite includes the following step: mixing at least one type of peptide, and/or at least one type of protein and enzyme and a composting agent and an additive to form a mixture, forming peptide-polyolefin polymer pellets through plasticization and combination with at least one type of polyolefin polymer, adding fine powder of ground dried renewable agricultural vegetal waste powder and a plastic assisting agent, and compounding and extruding with a twin-screw type extruder or a kneader mixer for forming pellet to obtain bio-renewable, biodegradable, biocompostable and biodigestible agricultural vegetal waste-peptide-polyolefin polymer pellets.
