Wax Worm Saliva Rapidly Breaks Down Plastic Bags, Scientists Discover
Polyethylene makes up 30% of all plastic production and is used in bags and other packaging that make up a significant part of worldwide plastic pollution. The only recycling at scale today uses mechanical processes and creates lower-value products. Chemical breakdown could create valuable chemicals or, with some further processing, new plastic, thereby avoiding the need for new virgin plastic made from oil. The enzymes can be easily synthesised and overcome a bottleneck in plastic degradation, the researchers said, which is the initial breaking of the polymer chains. That usually requires a lot of heating, but the enzymes work at normal temperatures, in water and at neutral pH.
