This dataset represents the activity of waste disposal of waste expanded polystyrene in a municipal solid waste incinerator (MSWI) // Recommended use of this dataset: For EPS, which goes to incineration as part of communal waste mixture. Larger amounts of clean, separated EPS could go to recycling. For non-expanded polystyrene use other dataset. // // Waste composition (wet, in ppm): upper heating value 33.2 MJ/kg; lower heating value 32.2 MJ/kg; H2O 1988.4; O 38626; H 77592; C 863430; S 674.8; N 1931.3; P n.a.; B n.a.; Cl 1125.5; Br 6700; F 14.167; I n.a.; Ag n.a.; As 1.8311; Ba 179.73; Cd 23.201; Co 30.444; Cr 39.382; Cu 106.94; Hg 0.81832; Mn 77.018; Mo n.a.; Ni 19.852; Pb 14.848; Sb 41.408; Se 2.0238; Sn 25.255; V 277.7; Zn 829.75; Be 0.48186; Sc n.a.; Sr 85.289; Ti 963.72; Tl 0.38549; W n.a.; Si n.a.; Fe 3590.5; Ca n.a.; Al 192.74; K n.a.; Mg n.a.; Na 1412.3; // 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. From this waste, the FLUWA process in the technology mix recovers 0.00065kg (DM) of a hydroxide sludge to be recycled in zinc furnaces. // Ultimately one kg of this waste produces 0.02981 kg of bottom ash (can include some washed ash) and 0.006424 kg of residues, which are landfilled (technology mix). Additional solidification of residues with 0.002569 kg of cement.Net energy production: 4.07MJ/kg electric energy and 7.88MJ/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.
