生命周期评价(LCA)作为一种有效的环境管理工具,是实现人类社会可持续发展的重要手段,但是目前国内还尚未有关于LED照明产品的生命周期评价。本文综述了生命周期评价方法在LED照明领域的应用,并对其中的清单分析部分进行重点讨论。清单分析是LCA中继目标界定后的一步重要操作,工作量极大,数据的准确选择对LCA清单数据库的研究十分重要。 相似文献

人工纳米材料(Engineering Nano Materials,ENMs)因具有优越的磁性、导电性、光学性质等被广泛应用于微电子学、催化、燃料电池、材料科学、生物技术和医药等领域,其带来优良性能与卓越功能的同时,其资源能源效率以及对生态环境、人体健康的潜在影响也越来越受到重视。尽早识别这些利弊对材料科学的发展、环境保护以及ENMs的可持续性发展均具有重要意义。而生命周期评价(Life Cycle Assessment,LCA)作为一种综合而全面的评价理论与方法,也是评价ENMs以及其工艺、产品的生命周期资源能源消耗和环境行为的有效方法。对生命周期理论与方法应用于ENMs及其产品的资源能源消耗分析、环境影响评价和环境释放分析三方面的研究进展进行了总结和综述,对目前研究中存在的问题进行了分析总结,对今后LCA应用于ENMs的发展方向进行了展望。 相似文献

采用国内杨建新生命周期评价(LCA)和国外荷兰的EI99两种方法比较了新兴装饰材料铝塑板和单铝板的相对环境负荷。采用EI99方法得出的铝塑板与单铝板的环境负荷的相对值与采用国内杨建新LCA方法计算得出的结果近似相等,由此可知,如果为了检验某种评价方法的准确性时,对类似产品/材料进行环境影响评估对比,采用两套以上的方法加以相对误差比较的做法是可行的。 相似文献

This article summarizes the thinking behind the call for a revolution/an evolution in China's energy production and consumption. China is still a developing country, though it has experienced fast economic growth in the past thirty years. It achieved great accomplishments surprising the world, and it is also confronted with challenges on energy supply and environmental protection. As environmental pollution becomes more and more serious, the energy challenges have become more and more complicated. With this in mind, the authors analyzed China's energy situation, China's energy supply and consumption, the world energy map, China's commitment both to improving its domestic environment and fulfilling its international obligations to control climate change. Action plans are presented to support the call for a revolution/an evolution in China's energy production and consumption as an effective assurance for China's ambitious goal of building a moderately prosperous society in all respects. 相似文献

It cannot be denied that environmental consciousness is becoming important. Ironically, legislation is probably the most satisfactory driver for pushing manufacturers to take environmental concerns into design considerations. In fact, the European Union introduced a new law (directive 2005/32/EC) for regulating the environmental consequences of all energy-using products (EuPs) in August 2007, the scope of which covers all products that rely on energy sources in any form for operation. Design alternatives are required in the product development stage so that environmental concerns can be considered as a decision parameter. In complying with the directive, life-cycle assessment (LCA) is a useful tool to draw conclusions and to compare the performance of alternatives. In this connection, a case study is carried out to assess the environmental impact of a personal electronic product through LCA, subject to the scope of the stated directive. The objectives of this paper are threefold: (i) to report the case in relation to the directive; (ii) to summarise the results of the LCA accordingly; and (iii) to suggest a new conceptual design and to compare the LCA of this new design with the original design. 相似文献

The construction, maintenance and disposal of asphalt pavements may lead to considerable environmental impacts, in terms of energy use and emissions during the life of the pavement. In order to enable quantification of the potential environmental impacts due to construction, maintenance and disposal of roads, an open life cycle assessment (LCA) framework for the asphalt pavements is presented in this paper. Emphasis was placed on the calculation and allocation of energy used for binder and additives at the project level. It was concluded from this study that when progressing from LCA to its corresponding life cycle cost, the feedstock energy of the binder becomes highly relevant as the cost of the binder will be reflected in its alternative value as fuel. Regarding additives like wax, a framework for energy allocation was suggested. The suggested project level LCA framework was demonstrated in a limited case study of a Swedish asphalt pavement. It was concluded that the asphalt production and transporting materials were the two most energy-consuming processes, emitting most greenhouse gases depending on the fuel type and electricity mix. 相似文献

By comparing existing studies and additional scenario calculations it was shown that energy data plays a central role in environmental life cycle assessments (LCA) of packaging materials. More attention should be paid to correctly linking environmental data from energy studies to packaging LCA, if possible adapting the data base to the local conditions. In general terms, it was shown that it is possible to calculate energy and packaging systems separately, because of the predominantly static links between the two. Scenario calculations show that the potential for reducing the environmental impact of packaging production by the use of cleaner energies is still considerable. 相似文献
