Location: RER - Europe
This dataset represents the production of a stationary electric wood chopper. A stationary chopper is used at sawmills to produce wood chips from industrial residuals.
The estimate of the dataset is very rough and the dataset is thus not more specific than average European production. Due to this uncertainty the dataset must only be used to consider the infrastructure needed for chopping industrial residue wood if the infrastructure is not relevant.
Several types of choppers exist; here only one model is developed and the uncertainty, especially for energy consumption, is rather high.
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.
