Biomass briquettes, biomass densification, bioenergy, density, heating values, MDF residues, wood residuesAbstract
In the forest production process, large quantities of lignocellulosic residues are generated, requiring strategies for their valorization and reuse. This study evaluated the physical, mechanical, and energetic performance of briquettes produced from Pinus sp. sawdust and from mixtures of MDF industry residues with Pinus sp. and Eucalyptus spp. sawdust. The briquettes were characterized in terms of apparent density, friability, and energetic properties, including proximate analysis and higher, lower, and net heating values. The results show that raw material composition has a direct influence on briquette performance. Briquettes produced from Pinus residues exhibited superior energetic properties, whereas those containing Eucalyptus presented higher apparent density and lower fines generation, indicating greater physical stability. The incorporation of MDF industry residues in combination with sawmill materials represents a viable alternative for producing briquettes with more balanced physical and energetic properties, contributing to the utilization and energy recovery of lignocellulosic residues.
