The reference for milling is 1 kg of metal removed. As there is a large variation from factory to factory with regard to the LCI, it is advised that in case this dataset becomes important in the results, it has to be investigated further if the rough estimations made are applicable or not. If you do not know how much has been removed by turning you can use 0.23kg of this process per kg of final product as an average assumption.
[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 ( 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.
