作为 CORRIM 第二阶段林业和木制品生命周期清单 (LCI) 研究的一部分，这项研究完成了美国西北内陆地区生产的软木材生产的全生命周期清单 (LCI)。数据是通过对代表性软木生产商进行调查收集的。原材料使用、热能、燃料、电力消耗和相关木材生产排放代表了 LCI 的输入数据。代表性软木制造商的年产量合计占地区年产量 755,852 m 3 的 16%。热能需求对木材生产的总能源消耗做出了重大贡献。在本研究中，大约 72% 的总能量用于将生材干燥至 15% MC。热能由木材燃料和天然气产生，分别占总量的 54% 和 46%。
As part of CORRIM Phase II life-cycle inventory (LCI) studies on forestry and wood products, this study completed a gate-to-gate life LCI for the production of softwood lumber produced in the Inland Northwest region of the US. Data were collected by surveying representative softwood lumber producers. Raw material use, heat energy, fuels, electrical consumption, and associated wood production emissions represented input data into the LCI. The combined annual production of the representative softwood manufacturers was 16% of the total annual regional production of 755,852 m 3 . Thermal energy requirements made a significant contribution to the total energy consumption for wood production. In this study, approximately 72% of the total energy was used for drying green lumber to 15% MC. Thermal energy was generated both from wood fuel and natural gas, representing 54 and 46% of the total, respectively.
