Summary

Scientists found that adding a special additive (called a Biotransformation Masterbatch) to common plastics like polyethylene and polypropylene, found in packaging and single-use items, allowed them to fully break down in soil, something these plastics have never been shown to do before. Importantly, the breakdown process didn't harm soil or water organisms and didn't disrupt the natural microbes in soil, suggesting this could be a safer way to reduce plastic waste that would otherwise persist for decades and break into microplastics. While this doesn't directly address existing microplastic pollution, it points to a promising path for making future plastic products less likely

Polymers

Polyolefins, commonly used in packaging and single-use products, are notoriously persistent in the environment, contributing significantly to environmental pollution. In scientific literature to date, polyolefins have not been reported to fully biodegrade. This study examines the biodegradation potential of polyolefin materials, specifically polyethylene (PE) and polypropylene (PP), enhanced through the incorporation of Biotransformation Masterbatch technology. The inclusion of the Biotransformation Masterbatch accelerated and enabled the full biodegradation of PE and PP, as demonstrated by laboratory weathering, and biodegradation studies in soil at mesophilic temperatures. Ecotoxicity tests revealed no adverse effects on test organisms in both soil and water environments, while metagenomics analysis demonstrated that biodegradation of these polyolefins did not significantly change the soil microbiota composition, which showed higher metabolic activity compared to virgin plastic controls. These findings demonstrate that Biotransformation technology provides an effective solution for delivering polyolefin-based materials with reduced environmental impact. It offers a sustainable alternative to conventional plastics, preserving the performance characteristics of traditional polyolefins while addressing the problem with fugitive plastic waste in the environment.
