Use system of biomass resources for feedstock of energy and material should be developed based on a region scale and bio-refinery concept. To use the biomass resources thoroughly, determination of an available amount of biomass resources based on the biomass resources production and its utilization in the region is needed. We estimated available amount of biomass resources based on study of production and utilization of crop residues and food processing factory wastes in Northeast Thailand. We carried out survey of yield and residue production of rice, cassava and sugarcane which are main crops in Northeast Thailand, and carried out interview to farmers and food processing factories related with the crops in 2004-05. Using these results, annual biomass production except for food is estimated as 1.87 M t from paddy fields and rice mill factories, 0.62 M t from cassava fields and cassava starch processing and tip factories and 2.63 M t from sugarcane fields and sugar mill factories in Khon Kaen Province in 2003-05, and available amount of the biomass resources is estimated 0.37M t, 0.35 M t and 0.42 M t, respectively.
