BIOBUILD incorporates a selected bioPCM (ethyl palmitate) into the cells of solid wood, wood particles, fibres by impregnation and optimize the bioPCM uptake to eliminate leaching. Simulteniously three bio-binders for wood fibre-bioPCM composites using a) polymerizable plant oils, b) lignin, and c) fungal mycelia are studied, optimized and produced. The binders and the solid wood impregnated with bioPCM demonstrate and validate the above technologies by production of wood fiber-bioPCM composites as building material (wallboards) and solid wood flooring (parquet) with improved thermal performance.
The operational environment as system prototypes (TRL7) is employed to demonstrate house wood construction prototypes with integrated novel wallboards and parquet and evaluate the energy-saving performance of the prototype houses in Spain and Sweden. The project validates the novel building materials and houses by their durability and exploitation properties, fire retardancy, volatile organic compounds (VOCs) and aesthetic perception.
The project employs ex-ante life cycle assessment (LCA) for each product and investigates long-term recyclability to ensure that the materials meet improved sustainability, circularity, and safety standards. The project is a part of the clustering activities of other European projects and initiatives as well as disseminate widely the integrated breakthroughs and results of the project to facilitate acceptance among stakeholders and society. Determine the industrial, environmental, social and economic challenges and benefits of the new technologies to facilitate their market uptake and transferability to other bio-based materials.
