This activity is a linking activity, i.e. it connects cottonseed meal with generic protein feed market. Cottonseed meal is used mainly as a feed for animals, thus traded on generic feed market with other protein - containing products.
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.
