This report examines the widely promoted pyrolysis method in plastic waste management, shedding light on its inherent limitations. Pyrolysis has been hailed as a solution by industry, but this study reveals significant drawbacks. Incompatibility with different plastic types, low oil yield, and contamination issues mean that the resulting pyrolysis oil must be heavily diluted with petroleum-based mixtures, in some cases at a ratio of over 40:1. To be used in recycled plastic production, the oil requires energy-intensive purification steps or substantial dilution with virgin petroleum naphtha, both of which are not aligned with the objectives of the EU Green Deal.
