Leachate - SLF - sludge from pulp and paper production (treatment of - wastewater treatment)

The activity generating the emissions is treatment of leachate, SLF, sludge from pulp and paper production, wastewater treatment. The reference product is leachate, SLF, sludge from pulp and paper production. Leachate, SLF, sludge from pulp and paper production is a by-product (wastewater) under the category of industrial wastes. It is generated in sanitary landfilling (SLF) of sludge from pulp and paper production. By the database default (and per unit of reference product),leachate, SLF, sludge from pulp and paper production has the following physicochemical characteristics: C: 0.6622 kg/m3, N: 5.9788 kg/m3, P: 0.097458 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.
