Wastewater from liquid crystal display backlight production (treatment of wastewater from liquid crystal display backlight production wastewater treatment)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. The product 'wastewater from liquid crystal display backlight production' is a by-product (wastewater) produced from industrial sources. It is generated from liquid crystal display backlight production activities. By the database default (and per unit of reference product),'wastewater from liquid crystal display backlight production' has the following physicochemical characteristics: C: 0 kg/m3 N: 0.000676 kg/m3 P: 0 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 (wastewater) is generated from ordinary transforming activities and as such can be considered for modelling wastewater outputs of comparable composition. 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 cut-off classification is Waste. The activity type is ordinary transforming activity. The reference product amount is -1.
