Paragraph starter
According to Tournier et al. (2023), enzymatic biocatalysis offers a significant advancement in plastic waste management by enabling the degradation and subsequent recycling or upcycling of commodity plastics such as polyesters and polyamides. This approach is crucial for transitioning towards a circular economy, as it provides a sustainable alternative to landfilling and incineration, thereby reducing environmental impact and promoting resource efficiency in design.
