PolyEthylene and PolyPropylene plastics (PE/PP) are primary components of single-use plastic waste generated by Hospitals. Pyrolysis is a common technique used to convert plastic waste into energy in the absence of oxygen, generating liquid and gas products.
We propose to convert pyrolysis liquid into high calorific gases – especially methane, ethane, butane, propane: i.e., the Natural gas components – by catalytic cracking using a range of ZSM zeolite catalysts. The aim is to apply the process to real pyrolysis oils as opposed to cracking single pure chemicals.
Sounds simple enough, but the importance of completing this proof of concept is to fully investigate the literature, and show that pyrolysis liquid produced from plastic waste can be converted to gas within the local laboratory environment. We aim to identify the challenges for upscaled Hospital PE/PP rich waste processing.
