F) ABSTRACT: Every year in the world, millions of tons of harvest residues are generated, such as, corn stalks and corn cob blanks, wheat, soy and rice straw, sunflowers, and rice husk. Those harvest residues can be used as a replacement for fossil fuels and represents a renewable energy source. Ash, which is generated by combustion of harvest residues, is usually deposited in landfills, causing environmental pollution and potential human health risks. These risks are caused by non-existent bio-ash management and the absence of pollution control [1]. In order to promote biomass as an energy source, the available quantities of agricultural biomass in Croatia and Serbia are presented. Its heating power is determined and compared to the heating power of standard energy sources. The possibilities of using biomass ash as a waste material in the building industry are outlined. As presented in [2-4], different kind of biomass ashes can be successfully used to replace cement in mortars and concrete and have positive influence on geotechnical properties of the soil. Preliminary results of ash suggest that these ashes exhibit the potential for use in the building industry, but because of the differences in their characteristics, each of them needs to be investigated in more detail.
