摘要
生命周期评价是一种评价产品、工艺过程或活动从原材料的采集和加工到生产、运输、销售、使用、回收、养护、循环利用和最终处理整个生命周期系统有关的环境负荷的过程。生命周期评价既可以作为评价产品生产全过程的有效手段,又可以作为一种环境管理工具,现已在国际上广泛应用。文章从生命周期评价的概念入手,介绍了生命周期评价产生背景、技术框架、评价方法、应用及其展望。
Life cycle assessment is a process of evaluating environmental load which relates to the entire life periodic system of a product, the technological process or the activity. The entire life periodic system mentioned above means from the raw material gathering and manufacture to the production, transportation, sale, use, recycle, maintains, circulation use and final disposal. Life cycle assessment can be the valid means which evaluates the whole process of the product production, and also can be a kind of environment management tool, which now already extensively applied among nations. The paper starts with concept of life cycle assessment, introducing the creation background, technique frame, evaluating method, application and outlook of life cycle assessment.
