我们研究的目的是确定森林木质废弃物生物质作为可再生能源的潜力。这项研究是对波兰一个林业部门的案例研究。这项研究是在波兰东部的Staszow森林区进行的。该司是拉多姆地区国家森林局的一部分，森林面积为19 335.12公顷。该研究涵盖了森林的间伐和砍伐，并以2012-21年森林管理计划及其清单数据为基础。在研究过程中，测定了林分的地上部分直径和蓄积量等基本特征。分析了林分的年生长量（单位：m 3 /ha年）和平均年龄，以估计获得的木材和生物量用于能源发电。每年可用于产生能源的木材废料量为12，269吨，来自收获切割和中间切割，另外还有7，267吨/年来自木材加工。这些木质生物质所产生的能源将为14，866人提供电力，并为3，153户家庭供暖一年。因此，我们认为，从一个普通农村社区的森林中获得的能源可以满足其一半居民的需求。
The aim of our study was to determine the potential of forest woody waste biomass as a source of renewable energy. The research is a case study of one forest division in Poland. The research was made in Staszow Forest Division, Świetokrzyskie Voivodeship, eastern Poland. The division is part of the Regional State Forest Directorate in Radom and covers a forest area of 19,335.12 ha. The research covers thinning and felling of forests, and was based on the forest management plan for 2012-21 and its inventory data. During the research basic features of forest stands, such as diameter and volume of aboveground, tree parts were determined. The annual growth of a timber stand in [m 3 /ha year] and the average age of the stand were analyzed to estimate the amount of obtained wood and biomass for energy generation. The amount of wood waste that could be used to generate energy is 12,269 t annually both from harvest cutting and intermediate cutting, and additionally 7,267 t/year from wood processing. The energy that could be generated from this amount of woody biomass would allow for electrical power for 14,866 people and heating 3,153 one-family houses for a year. Therefore we claim that the energy obtained from the forest of an area of average rural community meets the needs of half of its inhabitants.
