Reference product: aluminium removed by milling, small parts [kg]
Location: RoW - Rest-of-World
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 (https://www.ecoinvent.org/login-databases.html). The dataset may subsequently have been subjected to central changes to the database, as described in the respective change report for each new release.]
[This dataset has been generated using the system model "Allocation, cut-off by classification". A system model describes how activity datasets are linked to form product systems. The allocation cut-off system model subdivides multi-product activities by allocation, based on a physical properties, economic, mass or other properties. By-products of waste treatment processes are cut-off, as are all by-products classified as recyclable. Markets in this model include all activities in proportion to their current production volume.
Version 3 of the ecoinvent database offers three system models to choose from. For more information, please visit: https://www.ecoinvent.org/database/system-models-in-ecoinvent-3/system-…)]
