Molly Morse from Mango Materials, a company which has found a way to turn methane into biodegradable plastic, has been announced winner of the Postcode Lottery Green Challenge and with it $500,000.
The process sets up a loop. Methane gathered from waste plants becomes affordable bio-based, biodegradable plastics which can return to methane when they decompose and restart the cycle. Recycling becomes cycling.
