摘要：This study, conducted along the year 2003, was held in the environment of a cement company plant located in the São Paulo State. That industry has used carbon black as predominant energetic source which besides resulting a huge emission of gases (CO and CO2) into the atmosphere, has been more expensive than some other alternatives of biomass sources. Taking into consideration the location of that plant, there was a large supply of available biomass to be used as alternative fuel for industrial ovens. Several biomasses were analyzed and it was concluded that the sugar cane bagasse and residues of wood (sawdust and woodchips) were the most appropriate alternatives to such an industry.
