The multioutput-process 'mining, gravel / sand' delivers the co-products 'sand, at mine' and 'gravel, round, at mine'. The typical production mix in Switzerland is: sand 35% and round gravel 65%. From the total sectoral production volume (100%) of mined gravel round, crushed and sand, about 85% is gravel round and sand.

[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-…)]
