Catalyst turns mixed plastic waste into natural gas

via Chemistry World

Plastic waste can now be efficiently converted into methane using a ruthenium-based catalyst. The patented technology could help mitigate the planet’s growing plastic waste problem while producing methane for use as a fuel or chemical feedstock in a more environmentally friendly way than fracking.

Recovering chemicals and fuel from plastic waste streams is nothing new. Processes including pyrolysis and gasification, which break down plastics using high temperatures and catalytic processes, can recover useful materials. However, these approaches create several products, including waste, and require additional processing and purification.
