To fill the tasks of the energy industry development on local types of fuel it is necessary that the whole potential of the republic’s woodlands be included in timber management activities. At present only firewood and sawmill waste are utilized as fuels. Our analysis has shown that logging residues (cut off but-ends, stumps, lop and top) , unmarketable timber (brush wood) and dead wood could also be offered for the energy industry. An estimated 8.3 million cubic m of firewood could be harvested in Belarus from all timber felling operations in the near- and medium-term prospects. Logging residues will comprise 2 to 3 million cubic m. At the same time the use could be made of 70 percent of their mass. Sawmill waste (2 million cubic m) is to be completely utilized. Dead wood amounts to about 9-10 million cubic m, harvesting up to 40-50 percent of the stock being economically warranted. Hence, even in the medium-term outlook the total potential of wood pulp supplies for the energy industry will amount to 19-20 million cubic m which is equivalent to 3-5 million t of conventional fuel. However, logging residues and dead wood being uncalled, their estimate is approximate. Therefore it is necessary that in the coming 2 to 3 years techniques be developed for assessing wood pulp stock for the energy industry both in the regions and plausible biofuel plants
