Abstract

DIONIZIO, Aline Faleiro et al. Adding value to agro-industrial waste for energy purposes. Rev. de Ciências Agrárias [online]. 2019, vol.42, n.2, pp.251-260. ISSN 0871-018X.  https://doi.org/10.19084/rca.15129.

This work aimed to characterize and evaluate the potential energy production of both raw and carbonized residues from harvest and product processing of agriculture and forest crops. The experiment resulted in a completely randomized design with five treatments and three replicates. The evaluated properties were: granulometry, bulk density, elemental analysis, immediate analysis, calorific value and energy density. The data were submitted to analysis of variance and means were compared using the Tukey test at 5% significance. In conclusion, the in natura coffee bark presented the best properties for use in direct combustion, while wood residues charcoal presented better properties for energetic purposes among carbonized residues in study.

Keywords : biomass; combustion; carbonization.
