MODUWOOD - Modified Durable Wood Products

Projekt: Forskning

Beskrivning

The construction sector is responsible for a substantial amount of the regional, European and global carbon dioxide emissions. In order to reach national, European and global climate goals, these emissions needs to be decreased and an important contribution to this is a transition towards an increased use of wood based building materials. However, this requires the durability of these materials to be enhanced for applications in environments with high moisture levels, e.g. outdoors. Traditionally, degradation by wood degrading fungi has been reduced by impregnation of biocides, but the use of these substances is now restricted or forbidden due to health- and environmental reasons. Modern methods to protect wood from degradation aims at increasing the service life of the material by removing or reducing the cause of degradation: water within the
material. This can be done by wood modification, e.g. acetylation or heat treatment. However, there is a lack of understanding of what happens within the wood, which hampers optimization and development of modification techniques and processes. A better understanding of how modification affects the wood micro and nanostructure and water within the material is required to enable optimization of modification techniques and processes. Such optimization would result in more durable and cost effective wood-based products with increased possibilities to replace materials with high climate impact.

The aim of this project is to strengthen research and its connection to industry within material science with the purpose to develop durable, environmentally-friendly wood-based construction materials in the ÖKSregion. We will investigate how different types of modifications affects the water within wood on the micro and nanoscale by use of a combination of techniques available at Lund University and University of Copenhagen. This will result in new knowledge on how to produce new durable, environmentally-friendly wood-based construction materials by relevant industrial processes without using biocides. The access to competence, infrastructure and industrial contacts on both sides of Öresund implies that there is an underutilized potential to build an internationally strong research environment on material science within modified wood materials. Within the project, young researchers will be recruited to a postdoc-program which will contribute to that more researchers within the ÖKS-region will work with the subject and give the opportunity to attract international researchers to the ÖKS-region. The project has a strong connection to industry with companies that develop processing equipment to enhance the durability of wood as well as
producers of modified wood. The project also includes representatives from the wood industries in both Denmark and Sweden which enables the results of the project to be disseminated widely in both countries.
