Abstract: Hungary could potentially utilize a large amount of its agricultural residues for energy purposes. Common feature of this by-products is that they are originally difficult to handle and they have a small bulk density. Pellet production is one possible way to utilization, however the high ash content and low ash melting point of these residues cause problems in pellet burner equipment. The annual volume of usable agricultural by-products was estimated by using GIS methods and statistical databases. Two agripellet plants in the country are currently being examined for energy use and feedstock. Pellets have also been produced from various by-products (wheat straw, rapeseed stem, sunflower husk) under laboratory conditions.
