The BarkBuild project aims to address climate change mitigation by developing new, sustainable, and long-lasting wood building materials with low environmental impact. The project focuses on developing bark-based wood protection and building formulations that demonstrate technical performance, safety, and sustainability in both outdoor and indoor applications. The research objectives of the project include assessing the stability of different bark-based chemicals in wood impregnation and coating, optimizing the treatment for different Nordic wood species, characterizing the material properties and performance related to different use classes, and developing a pre-treatment for refractory spruce wood. The project also aims to reveal the penetration and distribution of polyphenols into the wood structure, elucidate the effects of impregnation with bark-derived chemicals on wood properties, and improve understanding of the feasibility and sustainability of the new formulations and construction materials. The project also seeks to improve human health by developing at least one volatile organic carbon (VOC) absorbing coating for indoor composite panels from bark residues.
