Reference product: shavings, hardwood, loose, measured as dry mass [kg]
Location: RoW - Rest-of-World
This dataset represents the planing of one m3 air dried hardwood lath that has been kiln dried to 10% moisture content. The planing mill is assumed to be located on the sawmill site. The suction of the shavings is modeled in a separate activity.
The data was provided by and approved by the Swiss forest industry (Holzindustrie Schweiz HIS).
Within ecoinvent, three products - boards, beams and laths - are distinguished:

After being sawn, the resulting products can either be air dried down to a moisture content of u=20% (mass of water per dry mass), kiln dried down to u=20% or kiln dried down to u=10%. The resulting products can then be planed (the ratio of planed products at a moisture content of u=20% reflects the market share of air dried and kiln dried unplaned products). The activity name indicates the respective product and moisture content of the product being planed.
[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-…)]
