Develope formaldehyde-free adhesives from rapeseed press cakes for production of particleboards and wood-panels

Reference number
Coordinator Sustainable Business Hub Scandinavia AB
Funding from Vinnova SEK 2 977 355
Project duration November 2020 - November 2022
Status Completed
Venture Joint R&D projects for small and medium-sized enterprises in Sweden-Germany
Call German-Swedish Call for joint R&D projects by Small and Medium-sized Enterprises fall 2019

Purpose and goal

The overall aim of the project has been to develop a binder based on residual products from the production of rapeseed oil (rapeseed cake) and to use the binder for wood-based products such as plywood boards and chipboards. The project succeeded in producing prototypes for both plywood sheets and chipboards with rapeseed protein as an important component of the binder. Market players show great interest and have given a positive response, they see great potential in our bio-based binder.

Expected results and effects

The results are partly technology-oriented, partly raw material-oriented. The project has shown that it is possible, in lab and pilot scale, to isolate rapeseed protein from rapeseed cake and use this in a binder, thereby creating bio-based formaldehyde free binder for various wood boards. The project showed the potential for rapeseed protein in a new area of use with great potential to contribute to a more sustainable construction industry, confirmed by the great interest from the industry.

Planned approach and implementation

The project has essentially developed a process where Lund University isolated rapeseed protein and delivered it to the German universities who prepared various binders and evaluated these in a number of wood-board applications. We developed several binders for production of different types of chipboards and plywood, which were tested according to European standards and discussed with the market. Our project contributes thereby to more bio-based construction and furniture industries.
