The inadequate disposal of agricultural harvest residue, or biomass, is an issue widely recognized in the typical agricultural region of Croatia’s and Serbia’s cross-border area. Biomass is cheaper than commonly used types of fuel in industry so using it as an energy source would benefit both the environment and the region’s competitiveness. The Eco build partnership approaches this challenge by proposing new ways of dealing with agricultural waste and informing the community on other solutions. By improving competitiveness of the regional economy and further developing the business environment, the partners of Eco build will develop new prototypes from biomass for further use in the construction industry and introduce new forms of cooperation among biomass providers and users, construction companies and research institutions.
