Fast-growing forest species established in tropical regions can supply much of the demand for renewable energy. The use of tree bark for energy is an alternative to gainfully exploit the residues generated by the forest industry. The aim of this study was to evaluate the potential of incorporation of bark in Schizolobium parahyba and Eucalyptus urophylla wood for energy purposes. The two species were planted with 3.0 m × 3.0 m spacing, in the central region of Brazil. The wood samples with and without bark were collected from trees, 3 years after planting to perform the physical and energy characterization of the biomass and the briquettes. The E. urophylla biomass presented better physical characteristics and lower ash content than S. parahyba. The presence of bark in E. urophylla and S. parahyba wood in small quantities (± 5%) is technically feasible for energy applications, including briquette production, thus offering an alternative for the destination of the residues produced in the wood processing industry.

速生森林树种木材中的树皮是否会显着改变能源潜力？

在热带地区建立的快速生长的森林物种可以满足可再生能源的大部分需求。使用树皮作为能源是一种有选择地利用森林工业产生的残留物的替代方法。这项研究的目的是评估出于能源目的，将树皮掺入副气生假单胞菌和尾叶桉木中的潜力。这两个树种在巴西中部以3.0 m×3.0 m的间距种植。种植后三年，从树上收集有树皮和无树皮的木材样品，以对生物量和煤球进行物理和能量表征。的尾叶桉生物质呈现更好的物理特性和低灰分含量比S. parahyba。少量（±5％）的尾叶大肠埃希菌和副沙门氏菌木材中存在树皮在能源应用（包括煤饼生产）方面在技术上是可行的，因此为木材加工工业中产生的残留物的目的地提供了替代方法。
