Information: 'fly ash and scrubber sludge' is a solid waste under the category of industrial wastes. It is primarily generated in a wide range of activities in electricity and heat production and metals processing.'fly ash and scrubber sludge' contain the following fractions: 100% separator sludge. By the database default (and per unit of reference product),'fly ash and scrubber sludge' has 90% water on wet mass basis (10% dry matter) and Carbon present is of only fossil origin (16.7% on a dry matter basis). It has a higher heating value of 0.9 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 (hazardous waste incineration). Based on the aforementioned treatments, this by-product receives, it is a hazardous waste. 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.
