Green News: Chemical recycling of polyethylene, and wax moths




New ways to recycle high-density polyethylene (HDPE) are emerging, at low energy cost. Chemists in the US have developed ways to break HDPE into monomers that can be re-polymerized as new plastics with properties similar to polyethylene.


Mother Nature, however, is already in on the action. Saliva from the larvae of the greater wax moth, Galleria mellonella, contains enzymes that break HDPE into shorter chains.
