生命周期评价在电子废弃物管理中的应用前景

 电子废弃物具有数量多、危害大、潜在价值高的特性,由于其具有丰富的可回收资源而被人们称之为“城市矿山”.但是如果对其管理不当,则会造成严重的环境污染,威胁到人类健康及生态安全.生命周期评价是一种用于评估与产品和服务有关的潜在环境影响的技术,其可以为电子废弃物管理提供一套系统的观点,汇总、评价其废弃后的各个过程中的消耗、排放及污染等各种指标,以帮助识别废弃电器电子产品管理过程中的潜在环境危害,指导电子产品的设计、流向及最终废弃的观念,为管理者提供决策支持.本文结合电子废弃物的特点,分析了在电子废弃物管理中引入生命周期评价方法的重要性,并探讨了生命周期评价在电子废弃物管理中的应用前景及存在的难点.

Application Prospect of Life Cycle Assessment in E-waste Management

The e-waste, characterized by its large quantity, the great hazard and a high potential value, is also called the "urban mine" due to various recyclable resources in it. However, the e-waste is related to a severe environment pollution and will become a threat to human health and ecological safety, if not properly managed. The life cycle assessment is a type of technology that evaluates the potential environment effects of products and services. This technology will help to identify the potential environment hazard in the management process of abandoned electrical products, to guide the design and the flow of electrical products, to establish the conception of abandoned products, and to support the management on the decision-making, by generating a series of systematic conclusions, including parameters in the consuming, emission and pollution processes after the electrical products are abandoned. This paper discusses the application prospect and existing difficulties of the lifecycle assessment in the e-waste management.
