This dataset represents the activity of waste disposal of hard coal ash in a municipal solid waste incinerator (MSWI) // Recommended use of this dataset: For small amounts of hard coal ash from small scale furnaces, which go to disposal as part of communal waste mixture. Larger amounts will be landfilled or could be used in building material production. // // Waste composition (wet, in ppm): upper heating value 0.4712 MJ/kg; H2O n.a.; O 298030; H n.a.; C 100000; S n.a.; N n.a.; P 980; B 350; Cl n.a.; Br 97; F n.a.; I 16.4; Ag n.a.; As 92; Ba 1960; Cd 4.5; Co 49; Cr 192; Cu 146.25; Hg 0.1; Mn 693; Mo 28.5; Ni 194; Pb 376; Sb 9.5; Se 7; Sn 19.8; V 388; Zn 475; Be 19.6; Sc 39.6; Sr 1940; Ti 5880; Tl 9.5; W n.a.; Si 245000; Fe 68600; Ca 19600; Al 166600; K 19600; Mg 58800; Na 9800; // Share of carbon in waste that is biogenic 0%. // 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 1.623 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. //
Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
