- Abstract
The multiple-species raw material and the poorly controlled carbonization in brick kilns are drawbacks for producing homogeneous and high-quality charcoal with the wood wastes derived from the sustainable forest management plans in Amazon. How much improvement is possible with the previous grouping of woods with similar properties is still unknown. Thus, the objective of this work was to compare the quality of charcoals derived from previously segregated into four distinct groups and non-segregated (traditional carbonization) wood wastes of 23 Amazon species carbonized in brick kilns. Charcoals were characterized by apparent relative density (ARD), moisture content (MC), friability (F), fixed carbon content (FC), volatile matter content (VM), ash content (AC), higher heating value (HHV), and energy density (ED). The group formed by the species Dinizia excelsa provided charcoals with the best quality (ARD = 0.737 g/cm3, AC = 1.20%, HHV = 28.9 MJ/kg, and ED = 21.3 MJ/m3). In contrast, traditional carbonization generated highly heterogeneous and friable charcoals. The segregation promoted average improvements of 22.0, 9.4, 2.0, 2.3, 1.0, and 23.6% in ARD, AC, FC, F, HHV, and ED of the charcoals, respectively. These results encourage the steel industry since it requires high-quality charcoal from legal sources for iron ore reduction.
