Next-generation engineered wood products using bio-based adhesives

The purpose of the project is to develop next-generation engineered wood products, bonded with bio-based adhesive systems that enhance performance, fire resistance, durability, and recyclability. A demonstrator will involve composite wood-based beams and columns (I-joists) for construction purposes. Most engineered wood products rely on petrochemical adhesives, which are derived from non-renewable resources, emit volatile compounds, and complicate recycling or reuse of bonded materials. Without innovation in adhesive systems, the sector risks being limited in its contribution to decarbonizing the built environment. The expected short-term results include validated adhesive formulations, demonstration of full scale I-joist prototypes, and performance benchmarks that meet or exceed industry standards. In the long term, the project will enable industrial adoption of bio-based adhesive systems, fostering a new generation of circular wood products with reduced carbon footprint and enhanced market competitiveness. The realization of the project is based on co-production of new knowledge between actors with expertise in along the value chain in wood products, adhesives and additives (SLU, Akzo Nobel, Sappi), industrial wood construction products (Masonite Beams), and agri-industry materials (Lantmännen). The project is embedded in a global trend of growing demand for sustainable construction, supported by regulatory frameworks, such as the Construction Products Regulation and REACH.
