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

Although the longitudinal chromatic aberration (LCA) of the adult eye has been studied, there are no data collected from the human infant eye. A chromatic retinoscope was used to measure cyclopleged infant and adult refractions with four pseudomonochromatic sources (centered at 472, 538, 589, and 652 nm) and with polychromatic light. The LCA of the infant eyes between 472 and 652 nm was a factor of 1.7 greater than the LCA found in the adult group: infant mean=1.62 D, SD+/- 0.14 D; adult mean=0.96 D, SD+/- 0.17 D. The elevated level of LCA in infant eyes is consistent with the greater optical power of the immature eye and indicates similar chromatic dispersion in infant and adult eyes. The implications for visual performance, defocus detection, and measurement of refraction are discussed.  相似文献

Life cycle assessment (LCA) is used by practitioners and policy‐makers to help them understand the sustainability impacts of packaging. LCA is useful because it quantifies the impact of a product throughout its life cycle, from raw materials extraction through to disposal or recovery. However, it can only ever be one input to decisions about the design or procurement of packaging. LCA has limitations as a tool to measure environmental impact and it does not currently evaluate social or financial impact. This paper provides a critical review of the role of LCA in evaluating packaging sustainability. It does this by evaluating the results of LCA studies that compare different types of carry bags and their implications for policy and practice. The benefits and limitations of this type of analysis are discussed. The case study of plastic carry bags demonstrates that while a scientific understanding of life cycle impacts is essential to support informed decision‐making, a broader sustainability analysis is required to ensure that all relevant issues are considered. These include the functionality of alternative bags, their relative cost, convenience for consumers and retailers, and the availability of reuse and recovery systems. An alternative approach, which evaluates packaging design within a broader sustainability framework, is presented and discussed. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

This article presents a new approach for incorporating process-integration tools into life cycle analysis (LCA) for biofuel production. Process synthesis techniques using mass- and energy-integration tools are employed to generate various scenarios for reducing mass and energy consumption in the process. The global implications of these changes and the associated trade-offs are assessed using the LCA tool: GREET. The developed approach enables the consideration of several levels of process integration while tracking the process economics and the reduction of the net greenhouse gas emissions. Several cases of biofuels with different processing technologies have been considered in this study, and the results show that when the process-integration tools are effectively utilized and combined with LCA, better insights are obtained and the net greenhouse gas emissions decrease drastically for different biofuels.  相似文献

Life Cycle Assessment as a tool for environmental management   总被引:1,自引:0,他引:1  
 This paper illustrates, using data from test cases, how Life Cycle Assessment (LCA) may be used to enhance environmental management, particularly when used in conjunction with Environmental Management Systems. There are a number of areas where LCA can be helpful: in the identification of significant environmental effects; in the quantification of those effects; in the assessment of year-to-year changes in environmental performance and in the assessment of the environmental benefits (or disadvantages) arising from changes (actual or planned) in operating conditions, equipment, procedures, raw materials or products. There are some issues which cannot (at present) be adequately assessed using LCA and these are also discussed. Received: 8 January 1999 / Accepted: 11 February 1999  相似文献

A number of software packages are available that are designed to facilitate making environmental comparisons between different packaging options, to facilitate ‘green’ packaging design and assessment of the environmental aspect of sustainability. Some of these (e.g. SimaPro and GaBi) are full‐fledged ISO 14040/14044‐compliant programs for life cycle assessment (LCA). Others are more limited, but are designed to be much simpler to use (e.g. COMPASS and Package Modeling). A systematic comparison of the evaluation of several packaging systems using COMPASS, SimaPro, GaBi, and Package Modeling found significant discrepancies in LCA results from different software systems. Availability of common impact categories among the software limited comparisons to four categories: greenhouse gas emissions, fossil fuel/non‐renewable energy, eutrophication, and water depletion. Given a common set of basic packaging containers as input, results from the LCA software systems being studied disagreed on which container had the greatest environmental impact, and in some cases results were more than an order of magnitude different between software. Discrepancies in results occurred in all four impact categories, and all four software systems disagreed with each other at multiple points in the comparisons. If there is to be increasing use of LCA analysis in guiding packaging design, this issue must be fully understood and resolved. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献
