2. Plastic Waste Properties. To achieve a very good heat/mass transfer during the pyrolysis process, plastic wastes are typically crushed, shredded and sieved to obtain small size flakes, i.e., less than 2 mm. Proximate and ultimate analysis of different plastic wastes are presented in Table 1 and Table 2.A high volatile matter content …

Abbott's work increasingly revolves around pyrolysis, which heats plastic waste in an oxygen-free environment to break down the plastic into its constituent parts. This complements mechanical recycling, as both approaches are needed to maximise recycling. There's no expectation of a one-size-fits-all approach to recycling, nor should …

The biomass pyrolysis process broadly consists of primary and secondary pyrolysis stages. During the primary pyrolysis stage, the decomposition of hemicellulose [15], cellulose [16] and lignin [17] will generate intermediates and primary products, such as non-condensable gases, e.g., CO, CO 2, H 2 O, and H 2, hydrocarbons, e.g., CH 4, C 2 …
