The inventory is mainly based on industry data and is completed, where necessary, by secondary data.100The data set represents the European situation, focusing on the main technologies, and the region specific characteristics.Components from aerated concrete are produced in fixed industrial processes. The main ingredients used in the aerated concrete block production are quartz sand with 60 to 70%, cement (type CEMI) with 20 to 30%, quick lime with 10 to 20% and gypsum with 2 to 5%. The rate of mineral production residues is considered with 3,5%. These residues are handled as inert waste, which are reusable in the building industry. The most important process steps are: 1. Preparation, doying and mixing of primary materials 2. Production and installation of the corrosion protective reinforcement (for reinforced components) 3. Casting of blocks 4. Hardening using steam 5. When necessary, further processing (rubbing and cutting) of the hardened aerated concrete parts. The assessment includes the life cycle from energy generation and raw material supply to the finished product on the factory gate. The infrastructure and the production of the manufacturing facility is not considered. Transports "gate to building site" are not part of the system and have to be considered afterwards.
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.Electricity grid mixDiesel mix at refineryThermal energy from natural gasSand (grain size 0/2) (EN15804 A1-A3)Lime (CaO; finelime) (EN15804 A1-A3)Cement (CEM I 32.5) (EN15804 A1-A3)Standard mineral product used in the construction industry according to the applied technology.Construction_aerated_concrete_reinforced_flowchart_3cb18481-4359-11dd-ae16-0800200c9a66.jpgLCI resultAttributionalNoneAllocation - market valueAllocation - net calorific valueAllocation - exergetic contentAllocation - massThe data of thermal energy used for steam hardening was available aggregated only. Therefore it is allocated by considering the steam effort in relation to the density of the products. 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.All data used in the calculation of the LCI results refer to net calorific value.NoneGaBi Modelling PrinciplesGaBi Water Modelling PrinciplesGaBi Agriculture Model DocumentationGaBi Land Use Change Model DocumentationGaBi Energy Modelling PrinciplesGaBi Refinery Modelling PrinciplesCut-off rules for each unit process: Coverage of at least 95 % of mass and energy of the input and output flows, and 98 % of their environmental relevance (according to expert judgement).NoneThe data set represents the industrial production of reinforced aerated concrete blocks used as wall material and elements in the building industry.
