Szepesi, Zoltán Siménfalvi University of Miskolc, Miskolc- Egyetemváros, Miskolc, H-3515, Hungary Abstract The paper presents a summary of the comprehensive research to develop an environmentally-friendly building system that improves the quality of life and can be produced under industrial conditions. The objective of the study is to develop a composite bridging element that can be eligible for the new requirements: withstand the mechanical load, good thermal insulation properties, and producibility with lower CO 2 emission. Biomass reinforced polyurethane foam as a potential composite material is used for the feasibility study. The mechanical and thermal behaviour of the composite bridging element with three different volume ratios of biomass were analysed using numerical modelling. The result of the feasibility study implies that the composite bridging element with the higher content of biomass reinforcement meets the expectations.

The production of conventional insulation materials such as mineral wool, glass wool, and polymer foams causes a large amount of carbon dioxide. Due to the global climate changes recent building industry directives target to decrease the amount of carbon dioxide emission. It requires developing new and innovative materials that usually The production of conventional insulation materials such as mineral wool, glass wool, and polymer foams causes a large amount of carbon dioxide.
