Reuse and lifetime extension strategies in the context of technology innovations, global markets, and environmental legislation [electronics]

There is a remarkable gap between the maximum technological lifetime of electronics and the real time of use, due to consumer pattern favouring the newest, most advanced devices. This development has to be complemented by sophisticated reuse strategies to keep reusable electronic components and equipment in the market. Thus, the eco-efficiency of use patterns for electronics products can be improved significantly. The paper discusses the current economic environment for reuse and the main technological obstacles, such as quality assurance for used components and logistics for providing used parts in adequate amounts. Three exemplary product categories - medical equipment, automotive electronics, and computers - are analysed and described referring to reuse strategies. For repair of computers, the "ecological payback period" is calculated as a measure for determining from an environmental perspective when repair results in a net environmental benefit. The European WEEE directive is analysed from the reuse point of view. Weak points of the directive concerning reuse and environmental impacts are discussed. An outlook on global reuse cascades for electronics products shows the implications and consequences of globalized end-of-life management.
