The raw materials per kg powder blend are mixed in following ratio: sand: 0.285kg, cement: 0.523kg lime hydraulic: 0.107kg, lime hydrated: 0.033kg, expanded polystyrene: 0.048kg, additives: 0.004kg. After mixing it is internally transported to the packing installation and packed. For the use 0.246 kg water has to be added (not included in this module). No direct process emissions are taken into account as they play a subordinate role compared to the emissions of the raw material production (e.g. drying of silica sand) and because no data are available. For inventoring the infrastructure, a yearly production amount of 150'000 tons is assumed. The lifespan of the machines is assumed to be 20 years.
[The full documentation of this dataset was originally provided in the corresponding ecoinvent report from the Swiss Centre for Life Cycle Inventories, which is accessible for free to guests and users of ecoinvent version 2 (https://www.ecoinvent.org/login-databases.html). The dataset may subsequently have been subjected to central changes to the database, as described in the respective change report for each new release.]
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.
