It is an end-of-life scenario (EN 15804 modules C4&D) which has a degradable organic carbon fraction (DOCf) wood value of 10%. This is based on emission factors provided in the Australia’s National Greenhouse Accounts (NGA) (Australian Government, 2016). This DOCf value can be considered extremely conservative when compared to values from later research (as used in the typical scenario) and effectively assumes that at least part of the wood waste is ground into a powder to accelerate degradation. The impacts associated with the landfill are declared in module C4. All landfill gas that is combusted for energy recovery (module C4) is assumed to occur in a power plant with an electrical conversion efficiency of 36% (Australian Government 2014, p. 189) and the resulting electricity receives a credit for offsetting average electricity from the Australian grid (module D) in line with EN 16485:2014 (Section 6.3.4.5).

Australian Government. (2014). Technical Guidelines for the Estimation of Greenhouse Gas Emissions0Landfill (NGA) in Australia.Foreground system:
The landfill scenario assumes the following for carbon emissions:
DOCf = 10%. This is the value chosen for Australia’s National Greenhouse Accounts (NGA).
Of the gases formed from any degradation of wood in landfill, 50% is methane and 50% is carbon dioxide (Australian Government 2014b).
All carbon dioxide is released directly to the atmosphere.
36% of the methane is captured, based on forecasted average methane capture in Australian landfills by 2020 (Hyder Consulting 2007). Of this, one quarter (9% of the total) is flared and three quarters (27% of the total) are used for energy recovery (Carre 2011).
Of the 64% of methane that is not captured, 10% (6.4% of the total) is oxidised (Australian Government 2014b) and 90% (57.6%) is released to the atmosphere.
In summary, for every kilogram of carbon converted to landfill gas, 71.2% is released as carbon dioxide
and 28.8% is released as methane.
Background system:
Electricity: Electricity is modelled according to the individual country-specific situations. The country-specific modelling is achieved on multiple levels. Firstly, individual energy carrier specific power plants and plants for renewable energy sources are modelled according to the current national electricity grid mix. Modelling the electricity consumption mix includes transmission / distribution losses and the own use by energy producers (own consumption of power plants and "other" own consumption e.g. due to pumped storage hydro power etc.), as well as imported electricity. Secondly, the national emission and efficiency standards of the power plants are modelled as well as the share of electricity plants and combined heat and power plants (CHP). Thirdly, the country-specific energy carrier supply (share of imports and / or domestic supply) including the country-specific energy carrier properties (e.g. element and energy content) are accounted for. Fourthly, the exploration, mining/production, processing and transport processes of the energy carrier supply chains are modelled according to the specific situation of each electricity producing country. The different production and processing techniques (emissions and efficiencies) in the different energy producing countries are considered, e.g. different crude oil production technologies or different flaring rates at the oil platforms.
Thermal energy, process steam: The thermal energy and process steam supply is modelled according to the individual country-specific situation with regard to emission standards and considered energy carriers. The thermal energy and process steam are produced at heat plants. Efficiencies for thermal energy production are by definition 100% in relation to the corresponding energy carrier input. For process steam the efficiency ranges from 85%, 90% to 95%. The energy carriers used for the generation of thermal energy and process steam are modelled according to the specific import situation (see electricity above).
Transports: All relevant and known transport processes are included. Ocean-going and inland ship transport as well as rail, truck and pipeline transport of bulk commodities are considered.
Energy carriers: The energy carriers are modelled according to the specific supply situation (see electricity above).
Refinery products: Diesel fuel, gasoline, technical gases, fuel oils, lubricants and residues such as bitumen are modelled with a parameterised country-specific refinery model. The refinery model represents the current national standard in refining techniques (e.g. emission level, internal energy consumption, etc.) as well as the individual country-specific product output spectrum, which can be quite different from country to country. The supply of crude oil is modelled, again, according to the country-specific situation with the respective properties of the resources.Diesel mix at refineryGravel (Grain size 2/32) (EN15804 A1-A3)Polyethylene Film (PE-LD) without additivesDried quartz sand (grain size 0/2)Asphalt binder (rolled asphalt) approximation <u-so>Expanded clay (EN15804 A1-A3)Electricity grid mixProcess steam from natural gas 90%Ammonia (NH3) without CO2 recovery (carbon dioxide emissions to air)Disposal of wood products in NGA Landfill.eol_landfill for wood products parameterised.jpgeol_landfill of wood products.jpgLCI resultAttributionalNoneAllocation - market valueAllocation - element contentAllocation - massAllocation - volumeForeground system: For refinery products, allocation is done by mass and net calorific value.
Background system: For the combined heat and power production, allocation by exergetic content is applied. For the electricity generation and by-products, e.g. gypsum, allocation by market value is applied due to no common physical properties. Within the refinery allocation by net calorific value and mass is used. For the combined crude oil, natural gas and natural gas liquids production allocation by net calorific value is applied.
