Description

Location: CH - Switzerland
This dataset represents the activity of waste disposal of residue from mechanical treatment, IT accessory in a municipal solid waste incinerator (MSWI) // Recommended use of this dataset: Only for incineration of shredder residues generated in the recycling (mechanical treatment) of computer peripherals (keyboards, mouse) // Inventoried waste contains 1.9% rubber; 46.5% Plastics from electronic consumer goods; 46.5% Plastics from electronic industrial goods; 1.57% MSWI iron scrap; 0.353% Alu in MSW; 1.03% Glass; 1.99% wiring copper; 0.0536% Pb in ASR inert; 0.0111% silver; . // Waste composition (wet, in ppm): upper heating value 34.31 MJ/kg; lower heating value 32.89 MJ/kg; H2O 8744.4; O 54844; H 70912; C 774420; S 408.04; N 12381; P 478.01; B n.a.; Cl 6321.9; Br 5119.9; F 232.72; I n.a.; Ag 110.86; As 6.9816; Ba 164.77; Cd 140.31; Co 27.44; Cr 70.858; Cu 23077; Hg 0.79127; Mn 44.112; Mo 2.7927; Ni 482.86; Pb 679.2; Sb 4467.1; Se 1.8241; Sn 199.49; V 4.6241; Zn 717.33; Be 0.43432; Sc n.a.; Sr 76.874; Ti 4167.6; Tl 0.34745; W n.a.; Si 6962.3; Fe 14273; Ca 3650.5; Al 5901.6; K 108.91; Mg n.a.; Na 797.06; // 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: 89.71%; Alu: 59.48%; Copper: 86.19%. // Recovery of metal scrap from bottom ash to recycling: 7.4029g iron scrap, 1.0141g aluminium scrap, 6.0778g copper scrap. From this waste, the FLUWA process in the technology mix recovers 0.000871kg (DM) of a hydroxide sludge to be recycled in zinc furnaces. // Ultimately one kg of this waste produces 0.09829 kg of bottom ash (can include some washed ash) and 0.01136 kg of residues, which are landfilled (technology mix). Additional solidification of residues with 0.004543 kg of cement.Net energy production: 4.23MJ/kg electric energy and 8.19MJ/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.

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%
