BLENDS OF AMAZONIAN SOCIOBIOECONOMY BIOMASS FOR THE PRODUCTION OF HIGH-EFFICIENCY ENERGY PELLETS

Resumo

The present article aims to present the criteria that guided the patent application BR102025008531-3, which introduces innovative biomass compositions (blends) formulated from underutilized lignocellulosic residues of the Amazonian socio-bioeconomy, such as açaí pits and fibers, Brazil nut shells, tucumã and cupuaçu shells and pits, as well as wood residues from forest management and silviculture, including pine, eucalyptus, pau-preto, mahogany, andiroba and other species. Aligned with the principles of the circular economy and the energy transition, the proposed invention aims at producing high-efficiency energy pellets for industrial applications. By combining the components in variable proportions (10–90%), the resulting pellets exhibit optimized characteristics: higher heating value (HHV) > 17 MJ/kg, moisture content < 10%, ash content < 2%, and mechanical durability > 95%. The production process involves conventional stages of drying, grinding, mixing, and compaction under high pressure. These pellets are understood to represent a sustainable alternative for thermal energy generation such as corn ethanol production, grain drying, steelmaking, and electricity generation in the Amazon region, promoting the valorization of regional residues and contributing to a diversified and low-carbon energy matrix.
