Circular Design and Use of Wood Building Elements

Project Details


The goal of Circular Design and Use of Wood Building Elements: DUET, is to develop utilization scenarios for solid industrial wood residues and recovered wood in high-value structural wall and floor elements, considering their technical and environmental feasibility and circular use.
DUET will develop the circular design of wall and floor elements using residues and recovered wood. These will be analyzed and tested with respect to the potential industrial use of recovered wood and residues with the goal of developing a hybrid (combination of residues/recovered and fresh wood) version of the element. Using residues in building elements should not only increase material efficiency, but also create added value. The elements will be further optimized according to the design for circularity concept, to enhance their lifetime and future circular use of the materials. To understand the material properties of residues and recovered wood and their application in building elements, we will characterize the properties of solid residues and recovered wood to determine how the ageing process and the use phase of wood influences its material properties and future use scenarios.
Using LCA, we will also assess the environmental benefits of using residues and recovered materials in the manufacture of the hybrid elements. This analysis is important to avoid inappropriate technical and product developments, as well as to identify rebound effects. Consequential LCA will be used to account for the market shifts induced by using residues and recovered wood. To address concerns over future recovered wood supply and utilization potentials, predictive models for Germany, Finland and Sweden will be optimized, using data about the quality and quantity of residues, and recovered.
The results will be used by the industrial partners and will inform policy making. They will also be published as scientific articles and in other formats to inform a wide audience about the possibilities of wood in a biobased circular economy.
