Data collected from mostly vertically integrated mills on a global level. The activity begins with untreated cotton fibres, which are first pre-treated before being dyed, and ends with cotton dyed. It includes electricity use and chemicals. It does not include the cotton fibres.
Wastewater emissions have been modelled based on primary data and completed with default data, considering wastewater treatment.
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.
