Based on the average composition of the mixed aqueous waste leaving the paracetamol process (high in TOCdegradable, acidic PH), the likely sequence of required wastewater purification technologies was determined as mechanical-biological treatment followed by incineration of excess sludge. Mechanical-biological wastewater treatment was modelled assuming that the microbial decomposition of organic compounds and nitrogen species proceeds exclusively via aerobic degradation to CO2 and H2O. Aerobic degradation reactions for all biodegradable compounds contained in the paracetamol process wastewater are listed in Table . A detailed account of the LCI calculations carried out to model the mechanicalbiological wastewater treatment process can be found in SI Section S6.2.
