Why have we not yet solved the challenge of plastic degradation by biological means?

The invention of fossil fuel-derived plastics changed and reshaped society for the better; however, their mass production has created an unprecedented accumulation of waste and an environmental crisis. Scientists are searching for better ways to reduce plastic waste than the current methods of mechanical recycling and incineration, which are only partial solutions. Biological means of breaking down plastics have been investigated as alternatives, with studies mostly focusing on using microorganisms to biologically degrade sturdy plastics like polyethylene (PE). Unfortunately, after a few decades of research, biodegradation by microorganisms has not provided the hoped-for results. Recent studies suggest that insects could provide a new avenue for investigation into biotechnological tools, with the discovery of enzymes that can oxidize untreated PE. But how can insects provide a solution that could potentially make a difference? And how can biotechnology revolutionize the plastic industry to stop ongoing/increasing contamination?

Automated summary

The invention of fossil fuel-derived plastics has had a positive impact on society, but mass production has led to a waste crisis and environmental issues. Scientists are exploring new ways, including biological methods like using microorganisms and enzymes from insects, to break down plastics more effectively. These efforts aim to revolutionize the plastic industry and address ongoing contamination.
