基于生命周期评价的3种木质类家具环境影响比较研究

Life Cycle Assessment Based Study of the Influences of Three Wooden Furniture on Environment

运用生命周期评价方法(LCA),通过构建木质家具的评价模型,对北京某大型家具企业生产的板木、板式和实木3类木质家具进行环境影响评价。结果表明,3类木质家具的综合环境指数分别为:115.33,54.26,157.91pt;主要环境影响因素分别为:化石燃料、土地使用、可吸入无机物、致癌物、气候变化。板式家具的环境影响值最小,实木家具环境影响值最大,板木家具居中。

Life cycle assessment （LCA）method was adopted to examine the impacts of three different types of furniture （frame board, panel and solid wood） produced by a large state-owned furniture enterprise on environment by establishing assessment models. The comprehensive environmental indices of the furniture being examined were 115.33 Pt, 54.26 Pt, and 157.91 Pt, respectively. The dominated factors influencing the environment were fossil fuels, land use, inhalable inorganic matter, carcinogens, and climate changes. Plate furniture had the lowest influence value on the environment, while solid wood furniture exhibited the highest influence value on the environment.
