Abstract
A precise establishing of quantity, share, structure and place where wood waste appears considerably influences the speed and direction of technological and energy development of wood processing plants. Technical and economic value of waste biomass projects energy usage and efficiency of a production plant. Lack of experimental studies and usage of general empirical relations are often reasons of inadequate practical compatibility and connection of waste biomass with total efficiency of the plant. Based on studies carried out in eight plants in the Republic of Croatia, it was possible to determine quantity, type, share, structure and place of wood residue/waste appearance in relation to annual raw material processing. Thermal and electrical energy consumption was measured during the thermal processing of sawn timber. Numerical values expressed the fuel and economic value, depending on the quantity and structure of waste biomass. The research suggests a new diagram for determination of existing efficiency and parameters for technical and economic values of waste biomass as one of the criteria for technological and energy development of wood processing plants.
