Research on the application of agricultural biomass ash in building products within the framework of Eco build project in Croatia

The paper presents the Eco build project whose idea is networking of science organizations with the industry by creating a crossborder network of owners and potential users of agricultural biomass/ ash. The available quantities of agricultural biomass in Croatia are presented and it is concluded that quantities are up to 10 times larger than the amount of available forestry waste that the current biomass power plants in Croatia use as energy sources. In order to promote biomass as an energy source, its heating power is determined and compared to the heating power of standard energy sources. The possibilities of using waste materials in building industry with emphasis on biomass are outlined ; wood chips and agricultural biomass. As the burning of biomass results in non-negligible amounts of ash, Eco build is investigating the possibilities of its application in building products for the purpose of its disposal. Preliminary results of ash of the sunflower seeds shells, wheat and barley straw ash as well as soybean straw ash suggest that these ashes exhibit the potential for use in building industry, but because of the differences in their characteristics, each of them needs to be investigated in more detail.
