摘要

The growing environmental burden of multilayer plastic waste demands recycling strategies beyond conventional methods. This study applies Life Cycle Assessment (LCA) to evaluate radiation-induced compatibilizer production using electron beam irradiation and its application in thatch panel manufacturing. The functional unit was 1 kg of compatibilizer, producing 357 panels. Results show a global warming potential of 14.355 kg CO2 eq kg−1, largely from electricity-intensive irradiation, but reductions in fossil resource use and human toxicity were observed. Benchmarking highlights trade-offs and suggests renewable electricity integration could improve sustainability, making radiation-assisted compatibilization a promising but energy-sensitive pathway.
