Raw sewage sludge (market for)

The activity generating the emissions is market for raw sewage sludge. The reference product is raw sewage sludge. Raw sewage sludge is a liquid waste under the category of industrial wastes. It is primarily generated in soft fibreboard production. raw sewage sludge contain the following fractions: 100% average raw sewage sludge with 97% water content. By the database default (and per unit of reference product),raw sewage sludge has 95% water on wet mass basis (5% dry matter) and Carbon present is of only non-fossil origin (40.96% on a dry matter basis). It has a lower heating value of 3.2 MJ/kg . This kind of by-product (recyclable or waste) is generated from ordinary transforming activities, and as such can be considered for modelling waste outputs of comparable composition. In the ecoinvent database, treatment option/s for this by-product include: thermal (municipal incineration). Based on the aforementioned treatments, this by-product receives, it is a non-hazardous waste. In addition, this by-product is used in the following processes: drying, sewage sludge. This by-product can be modelled on two levels: treatment activity and market activity. The former one refers to the specific technology treating the by-product while the latter level represents a mix of treatments. Users are encouraged to inspect the modelling assumptions of the treatment activities and when selecting the market to additionally inspect the treatment mix. Collection and transportation of this by-product is accounted in the respective market activity, users are advised to inspect and modify the average transportation distances for a case specific modelling. The reference product amount is -1. The cut-off classification is Waste. The activity type is ordinary market activity.
