The Wastewater life cycle inventory tool by 2.-0 LCA consultants

Very often the fate of chemicals after use is to be sent to municipal wastewater treatment plants (WWTPs), where they are subject to degradation. In many life cycle assessment (LCA) studies we need to account for the environmental impacts caused by the disposal of chemical substances down the drain, however existing LCA models for wastewater treatment typically reflect the average performance of WWTPs, rather than the specific fate of particular chemicals. Obviously, different chemicals behave differently in WWTPs, depending on their physical-chemical properties and biodegradability. An accurate modelling of the life cycle impacts of chemicals requires taking into account this specific behavior, namely whether a chemical will be either degraded, volatilized, partitioned to sludge, discharged unchanged, or a combination of these.
