材料周期寿命评价起源于1969年美国对饮料容器的能耗评价思路,以后“寿命周期评价”这一术语被正式提出,国际标准化机构ISO/TC207制定了其暂行标准。从材料的周期寿命出发,全面系统地考察材料从摇篮到坟墓全过程中的能源和资源消耗量、废弃物和污染物的排放量及其对环境的影响。这种思想在理论上讲是可行的,但真正 Material life cycle evaluation originated in the United States in 1969 on the evaluation of energy consumption of beverage containers, after the “life cycle evaluation ” is the term was officially proposed, the international standardization agency ISO / TC207 developed its interim standards. Starting from the life expectancy of materials, we comprehensively and systematically examine the energy and resource consumption, waste and pollutant emissions and their impact on the environment during the entire cradle to grave. This idea is theoretically feasible, but true
