Description

Reference product: three layered laminated board [m3]
Location: RoW - Rest-of-World
This dataset represents the production of one m3 three-layered laminated boards. The input of wood is assumed to be sawn timber spruce, i.e. a softwood.

The production takes place at a wooden board factory for organic bonded board; the data reflects a German production site from 1995, which is assumed to representative for Europe. The figures origin mainly from literature.

[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

Technology reflects the a medium-sized German enterprise from 1995.

The three-layered laminated board is actually a special form of plywood featuring relatively thick layers. The three-layered laminated board made of spruce is produced in a large wood processing company in the Canton of Fribourg, Switzerland: out of rough sawn timber (u=70%) 22 mm lamellas are sawn, which are technically dried, planed, finger-jointed, glued with PVAc-adhesive at their ends to “never-ending” lamellas and finally glued to a bloc. This block is sawn to boards, which are planed. The spruce is mainly coming from the area around Fribourg. The thermal energy for the drying of the lamellas is mainly produced by industrial residual wood (8% of wood input) (Werner et al, 1997).
