Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. The product 'electric arc furnace secondary metallurgy slag' is a solid waste under the category of industrial wastes. It is primarily generated in steelmaking process during the smelting process. 'electric arc furnace secondary metallurgy slag' contain the following fractions: 100% electric arc furnace secondary metallurgy slag. By the database default (and per unit of reference product) 'electric arc furnace secondary metallurgy slag' has 0.5% water on wet mass basis (99.5% dry matter) and Carbon present is of only fossil origin (0.08% on a dry matter basis). It has a lower heating value of 0 MJ/kg. 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 by-product include: deposition (residual material landfill). Based on the aforementioned treatments this by-product receives it is a hazardous waste.  In addition this by-product is used in the following processes: electric arc furnace secondary metallurgy slag to market for electric arc furnace secondary metallurgy slag for recovery.  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 cut-off classification is Waste. The activity type is market activity. The reference product amount is -1.

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.8. Slag is a by-product of the steelmaking process that is produced during the smelting process. Slags are principally composed of impurities in the charge and inert materials that are added in the beginning of the steelmaking process. Ladle furnace (LF) slags are typically recovered for use internally or externally (e.g. as an aggregate), although a portion may be landfilled or stockpilled. The cut-off classification is Waste. The activity type is market activity. The reference product amount is -1.
