| Abstract: Biomass is an important component of the Brazilian energy matrix, with a potential contribution of co-products from thinned forests. The aim of this work was to evaluate the energy balance and CO2 potential emission in mechanized biomass harvesting operations in Pinus taeda stands at 9 and 10 years-old and under thinning, searching to support the use of co-product biomass from thinning as a renewable energy source. Thinning was carried out through cut-to-length harvesting method, in which large logs for sawmill and small logs for energy were produced. In addition, tops, needles, barks, and branches were considered as co-products. The balance between consumed energy and emitted CO2 by machines for thinning in relationship to the energy and CO2 in... |

| The objective of this study was to evaluate the wood and charcoal quality of young Eucalyptus spp. trees, and to verify the influence of age and clone on the energy performance of these fuels. It was sampled the clones 1277 and 0321 of Eucalyptus spp. in two ages (46 and 58 months). The characteristics determined in the wood were: chemical molecular and elementary, basic density, carbon stocks and lignin by volume, the energy density and heating values (higher and lower). The charcoal was produced in an electric furnace (muffle) with the final temperature of 450 °C. It was conducted the mass balance and carbonization energy, beyond the immediate evaluation of the chemical composition, apparent density and calorific value of charcoal. The clone 1277, at the... |
