Waste - from silicon wafer production - inorganic (treatment of waste - from silicon wafer production - inorganic - residual material landfill)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. The product 'waste from silicon wafer production inorganic' is a solid waste under the category of industrial wastes. It is primarily generated in silicon wafer and photovoltaic cell production. 'waste from silicon wafer production inorganic' contain the following fractions: 100% inorganic waste silicon wafer. By the database default (and per unit of reference product) 'waste from silicon wafer production inorganic' has 9.4% water on wet mass basis (90.6% dry matter) and Carbon present is of only fossil origin (3.48% on a dry matter basis). It has no heating value. 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: deposition (residual material landfill). 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. The cut-off classification is Waste. The activity type is ordinary transforming activity. The reference product amount is -1.
