The Environmental Performance of Mixed Plastic Waste Gasification with Carbon Capture and Storage to Produce Hydrogen in the U.K.

Hydrogen of a high purity can be produced from the advanced gasification nonrecyclable mixed plastic wastes (MPW). Due to fossil nature MPW, carbon capture and storage (CCS) capabilities need employed for process considered low-carbon hydrogen production route. This study analyzes environmental performance semicommercial that (a) provides an end-of-life (EoL) (b) produces as main product (for sustainable manufacturing, heating, transport applications), (c) captures dioxide emissions which are injected into geological sites permanent sequestration. The climate change impact result is ?371 kg CO2 per 1 tonne MPW treated. was competitive against similarly modeled Waste-to-Energy (WtE) plant coupled with CCS?an alternative future scenario. WtE CCS corresponding 17 MPW. two technologies were also compared alongside decarbonizing electricity grid mix.
