Leachate - SLF - refinery sludge (treatment of - wastewater treatment)

The activity generating the emissions is treatment of leachate, SLF, refinery sludge, wastewater treatment. The reference product is leachate, SLF, refinery sludge. Leachate, SLF, refinery sludge is a by-product (wastewater) under the category of industrial wastes. It is generated in sanitary landfilling (SLF) of refinery sludge. By the database default (and per unit of reference product),leachate, SLF, refinery sludge has the following physicochemical characteristics: C: 0.33668 kg/m3, N: 0.21208 kg/m3, P: 0.003574 kg/m3. This by-product can have a regional-specific composition; users are prompted to refer to the properties of this wastewater (in activities treating them) for a detailed elemental composition. This kind of by-product (recyclable or waste) is generated in a specific treatment process, and as such is not intended to be used as for modelling waste outputs from other activities. In the ecoinvent database, treatment option/s for this wastewater include: wastewater treatment plant. 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 wastewater is accounted in the respective market activity with the use of sewer infrastructure; Transportation of wastewater through a sewer grid results in losses until the wastewater enters the wastewater treatment plant. Direct emissions due to those losses are considered in the market activity. Losses are regional specific and thus users are encouraged to inspect the regional modelling assumptions. The reference product amount is -1. The cut-off classification is Waste. The activity type is ordinary ordinary transforming activity.
