Abstract

Harnessing forest wastes as an energy source is an option for a better use of renewable resources, and a strategy for replacing fossil fuels. However, such wastes need to be improved for this function, and biomass compaction is a way to increase the quality of these materials for energy purposes. The objective of this work was to produce briquettes of two residues from Pinus spp. wood processing – sawdust and black liquor –, and to evaluate the different proportions of black liquor in the briquettes (0, 5, 10, and 15%). For the evaluation of briquettes, tests for expansion, apparent density, friability, immediate chemical analysis, superior calorific power, and energy density were performed. Increasing the black liquor percentage led to improvements in lateral and volumetric expansions, apparent density, volatile material content, and fixed-carbon content, but no gains were found for friability, height expansion, and energy characteristics of briquettes.
