Abstract
ABSTRACT A Life Cycle Analyses (LCA) assessment was evaluated comparing three harvesting systems on intensively managed Pinus radiata (radiata pine) plantations growing in the Biobío Region, Chile. Evaluated systems considered semi-mechanized, mechanized, and tower logging in steep slope forest operations. Our LCA study focused on CO2 e emissions from six harvesting activities: felling, logging, processing, sorting, loading, and transportation, all under the ISO 14040 and ISO 14044 standards. The average and maximum monthly production scenarios were the highest for the semi-mechanized system with 24 and 25.2 kg CO2 e m−3, followed by the tower logging with 23.2 and 24.5 kg CO2 e m−3 and, lastly, the mechanized system with 11 and 12.1 kg CO2 e m−3. Similar to other studies, harvesting phases that contributed the most were logging, loading and transport. Concerning LCA stages, forest equipment operation generated the highest CO2 e level across the three harvesting systems where fuel consumption was the activity that contributed with 76% of CO2 e for the mechanized system, and 50% in the case of the tower logging and semi-mechanized systems. The mechanized system had the highest fuel use efficiency and the lowest CO2 e emissions.
摘要生命周期分析(LCA)评估比较了智利比奥地区集中管理的辐射松(辐射松)种植园的三种采伐系统。评估了在陡坡森林作业中考虑半机械化、机械化和塔式伐木的系统。我们的生命周期评价研究重点关注六种采伐活动的二氧化碳排放:砍伐、伐木、加工、分拣、装载和运输,所有这些都符合ISO 14040和ISO 14044标准。半机械化系统的平均和最大月产量情景最高,分别为24和25.2 kg CO2 e m−3,然后是23.2和24.5的塔测井 kg CO2 e m−3,最后是11和12.1的机械化系统 kg CO2 e m−3。与其他研究类似,贡献最大的收获阶段是伐木、装载和运输。关于生命周期评价阶段,森林设备操作在三个采伐系统中产生了最高的CO2 e水平,其中燃料消耗是机械化系统贡献了76%的CO2 e的活动,在塔式伐木和半机械化系统的情况下贡献了50%。机械化系统的燃料使用效率最高,二氧化碳排放量最低。
