This means that the LCIA results for waste disposal may see an apparent increase in environmental impacts upon waste treatment optimisation due to a reduction in waste-toenergy derived credits. However, losses in credits would be compensated for by fewer impacts incurred from waste disposal due to reduced waste volumes, as well as by fewer impacts attributed to paracetamol production due to reduced resource consumption. Thus, the overall environmental performance of the novel process is likely to improve upon further implementation of reuse and recycling strategies despite a loss in waste-to-energy derived credits.
