The forest sector is vital in Europe, providing economic and social benefits to communities. However, this sector is also responsible for some environmental impacts, and it is crucial to ensure that these impacts do not outweigh the benefits described. For this reason, this paper proposes an environmental and economic assessment of three forest wood products – uncoated woodfree paper, natural cork stoppers, and particle boards. The life cycles of these products were modeled using foreground data and a life cycle assessment was conducted to determine the environmental impacts associated with these three life cycles. For the economic assessment, the net present value method was adopted. From the results, it is possible to conclude that the utilization of 1 ha of forest land for 100 years to plant Eucalyptus globulus used in the production of uncoated woodfree paper generates the least environmental impact per euro. A sensitivity analysis was conducted to determine the reliability of the results achieved given the uncertainty associated with the data used to model the three life cycles. The same critical impact categories and the same critical life cycle stage (raw materials’ extraction) were identified for the three systems under study. Given these similarities, an effort must be made by the forest sector to reduce the impacts of these categories and this life cycle stage. To assist on this task, a set of generic and industry-specific recommendations is provided for companies operating in the forest sector.

林木产品之间的经济和环境比较–未涂布的无木浆纸,天然软木塞和刨花板

林业部门在欧洲至关重要,可为社区带来经济和社会利益。但是,该部门还负责一些环境影响,因此至关重要的是确保这些影响不超过所描述的收益。因此,本文提出了对三种林木产品的环境和经济评估:未涂布的无木浆纸,天然软木塞和刨花板。这些产品的生命周期使用前景数据建模,并进行了生命周期评估,以确定与这三个生命周期相关的环境影响。对于经济评估,采用净现值法。从结果可以得出结论,利用1公顷林地持续100年种植球状桉树用于生产无涂层无木纸的纸张每欧元产生的环境影响最小。考虑到与用于建模三个生命周期的数据相关的不确定性,进行了敏感性分析,以确定所获得结果的可靠性。对于所研究的三个系统,确定了相同的关键影响类别和相同的关键生命周期阶段(原材料的提取)。鉴于这些相似之处,林业部门必须做出努力,以减少这些类别和整个生命周期阶段的影响。为了协助完成此任务,为林业部门的公司提供了一组通用的和特定于行业的建议。
