Description

Reference product: wood ash mixture, pure [kg]
Location: CH - Switzerland
This dataset represents the activity of waste disposal of wood ash mixture, pure in a municipal solid waste incinerator (MSWI) // Recommended use of this dataset: For small amounts of wood ash from small scale furnaces, which go to disposal as part of communal waste mixture. Larger amounts will be landfilled or as fertilizer on suitable ground. // // Waste composition (wet, in ppm): H2O n.a.; O 445010; H n.a.; C 12000; S 9200; N n.a.; P 9800; B n.a.; Cl 3200; Br n.a.; F n.a.; I n.a.; Ag n.a.; As 6.7; Ba n.a.; Cd 14.2; Co 18; Cr 194.9; Cu 163.2; Hg 0.1; Mn 19956; Mo 3.7; Ni 55.2; Pb 65; Sb n.a.; Se n.a.; Sn n.a.; V 39.5; Zn 1662; Be n.a.; Sc n.a.; Sr n.a.; Ti 1383; Tl n.a.; W n.a.; Si 82600; Fe 22833; Ca 284400; Al 20800; K 54500; Mg 32100; Na n.a.; // Share of carbon in waste that is biogenic 100%. // Share of metals in waste not oxidised and bulk-recyclable (exclude very small or thin parts) Iron: 0%; Alu: 0%; Copper: 0%. // Recovery of metal scrap from bottom ash to recycling: 0g iron scrap, 0g aluminium scrap, 0g copper scrap.Ultimately one kg of this waste produces 1.085 kg of bottom ash (can include some washed ash) and 0 kg of residues, which are landfilled (technology mix). Net energy production: 0MJ/kg electric energy and 0MJ/kg thermal energy. //
[This dataset has been generated using the system model "Allocation, cut-off by classification". A system model describes how activity datasets are linked to form product systems. The allocation cut-off system model subdivides multi-product activities by allocation, based on a physical properties, economic, mass or other properties. By-products of waste treatment processes are cut-off, as are all by-products classified as recyclable. Markets in this model include all activities in proportion to their current production volume.
Version 3 of the ecoinvent database offers three system models to choose from. For more information, please visit: https://www.ecoinvent.org/database/system-models-in-ecoinvent-3/system-…)]

Technology

average Swiss MSWI plants in 2010 (grate incinerators) with electrostatic precipitator for fly ash (ESP), wet flue gas scrubber and 25% SNCR , 42.77% SCR-high dust , 32.68% SCR-low dust -DeNOx facilities and 0% without Denox (weighted according to mass of burnt waste, representing Swiss average). Efficiency of iron scrap separation from slag : 58%. Efficiency of non-ferrous scrap separation from slag : 31%. The technology mix for this dataset includes a filter ash treatment (FLUWA) of a share of 46.22%. Gross electric efficiency technology mix 15.84% and Gross thermal efficiency technology mix 28.51%
