Bio-augmentation - Effective Method of Treating Plastic Waste - A field Study

A Critical Review of the Performance and Soil Biodegradability Profiles of Biobased Natural and Chemically Synthesized Polymers in Industrial Applications

“…Microorganisms having specific metabolic capabilities can be introduced into the plastic-contaminated site for enhancing the degradation of plastic waste. Both abiotic and biotic factors determine the success of bioaugmentation . Certain microbial strains may be added to the biobased or nonbiobased plastic polymers to enhance their biodegradability when disposed.…”

“…G. thermoleovorans was shown to successfully attach to the surface of PLA to result in a colonization that increased the rate of microbial degradation of the plastic . Other polymers such as polyolefins, polyurethane, and polyesters have also been studied for being reinforced with microbial cultures for bioaugmentation. − Since biodegradation of plastics takes place by extracellular enzymes (hydrolases) followed by intracellular accumulation by microorganisms and consumed as carbon sources. , Recent advancements have been taken to the next level by adding engineered enzymes into the polyesters. ,− DelRe et al (2020) developed polyesters with nanodispersed enzymes that degrades in damp composting soil by up to 98% after less than a week. The enzymes added in the polyester are activated by heat and moisture to degrade the plastic from the inside .…”
