It is assumed that most of the waste produced in Switzerland is also treated in Switzerland, that is why a regional Swiss market is created for the treatment of residue from cooling tower. The transport distances used for calculating the transport amounts in this market are taken from a model based on statistics on transport of goods in Switzerland (Valsasina, 2016, Default transport data per commodity group for Switzerland, ecoinvent, www.ecoinvent.org).
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.
