07 Oct 2022 --- Researchers from Ghent University, Belgium, have found that using pyrolysis as an advanced plastic waste recycling system could close the gap between petrochemical plastic production and end-of-life waste management such as downcycling, incineration and landfilling. Pyrolysis is chemical decomposition by using thermal energy at high heat. Performing pyrolysis on plastic waste creates an oil hydrocarbon, also known as bio-oil, that contains many different chemical compounds to be used for further chemical processing.
