RESUMO:

The sustainable use and commercialization of native wood for energy purposes depends on the determination of the difference between the amount of energy produced in areas under sustainable forest management and the understanding of the performance of this fuel in the main sector that consumes it in Rio Grande do Norte, of red ceramic. Within this context, the objective was to study the amount of energy of the wood stored in three different areas under sustainable forest management in the RN and the quality of the wood of Anacardium occidentale and Mimosa tenuiflora during the burning of pieces of red ceramics. For the study of article 1, 5 forest species for area I (Campo Grande), 6 for area II (Cruzeta) and 12 for area III (Touros) were selected based on the importance value index. Three trees were felled to obtain discs at 0, 25, 50, 75 and 100% of the commercial height of the tree. From this, the basic density, the upper calorific value and the calculation of the energy stored by species and area were determined. The experiment was evaluated according to the completely randomized design, with a factorial of 5 x 6 x 12, with three replicates (sample trees) in each area. For the article 2, the woods of Anacardium occidentale and Mimosa tenuiflora were used during the burning of the bricks and for that, three treatments were adopted, namely: (0JP) 100% Anacardium occidentale; (50JP) 50% Mimosa tenuiflora + 50% Anacardium occidentale; and (100JP) 100% Mimosa tenuiflora. The wood stacking factor of both species was determined by Newton method to determine the actual consumption of wood (st) per treatment and the total burning time and product quality were verified. It was concluded that there is a difference in the amount of energy stored in the wood of the studied forest species, which reflected in the energy productivity in each area under study. In this way, area III (Bulls) was highlighted by the greater potential of energy productivity due to the greater number of energy species. Regarding the wood performance of the species used during the burning of the bricks, the 50CJP treatment provided a reduction in the fuel consumption, as well as a higher percentage of ceramic pieces of the first quality.
