Description

Reference product: bark chips, wet, measured as dry mass [kg]
Location: RoW - Rest-of-World
This dataset represents the service of debarking softwood in forest with an output of one m3. The volume is excluding bark.

Debarking is one process step in the technical wood production with the main function of removing bark, bast, and dirt. The process data reflects Germany/Europe standards.

The data is mainly based on literature values.

[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-…)]

Technology

The process refers to a tractor driven process, i.e. a mechanical and mobile debarking process. Softwood is usually debarked in the forest with movable disbarkers.

The amount of bark, based on the total volume of the stem with bark is about 8 to 15% for spruce (Kollmann et al., 1975 and Sell, 1997).
