Abstract
The continuous development of new technologies for renewable solid biofuels upgrading, as well as the waste management concern due to biowaste accumulation in urban landfills, increased the attention to biomass as an energy resource. Recent studies had shown an encouraging evolution in thermal processing treatments aiming the enhancement of the lignocellulosic waste energetic potential. Knowing the benefits of torrefaction treatment, this paper aims to evaluate the thermal behavior of organic blends composed by pruning residues from different species with the most representativeness within the ecosystem forest of Brasília, DF. The biomass mixture was torrefied (225, 250, and 275°C) and chemically analyzed to assess the thermal treatment impact on the torrefied product. Regarding the energetic upgrade, results for the calorific power showed an enhancement of 2.63, 6.64, and 11.10% for 225, 250, and 275 °C torrefaction treatments, respectively. The results could give support to afforestation action bids in upcoming segments of the growing city, indicating specific tree species holding a higher energetic potential.
