The feasibility of including sustainability in LCA for product development

The feasibility of combining the concept of sustainability principles and the methodology of Life Cycle Assessment (LCA) is examined. The goal is to achieve an operational tool that incorporates sustainability in product development and strategic planning. While the method outlined has the structure of LCA, it emphasises aspects and parameters often omitted from traditional LCA. The analysis and results can be either qualitative or semi-quantitative. Although a qualitative analysis is less time consuming, it can still highlight the important issues. Qualitative information, which is easily lost in a quantitative analysis, can be emphasised. One of the conclusions is that the method is well suited for screening analysis.

A profile of environmental science in China

This paper concisely introduced the eco-environmental survey in China and the Chinese scientific programme for environmental research which is being practiced or being planned. China has established a nation-wide system relating to environmental scientific research and environmental administration and has taken the following strategies for solving the environment problems: (1) a series of laws and regulations for environmental protection has been promulgated so as to strengthen the legal administration and economic punishment. (2) the idea of ecological construction has been proposed for the purpose of taking the environmental protection work into the consideration of the national and provincial (or regional) economic construction planning. (3) spreading ecological engineering and ecological technologies have reduced the pollutant sources and have increased the industrial and agricultural economic profit.

我国电子废弃物收集体系构想

解决中国电子废弃物问题,一是控制电子废弃物进入非正式循环利用者手中;二是把非正式循环利用系统纳入良好的电子废弃物管理系统,使之成为更有效和对环境友好的系统.因此,如何把千家万户废弃的电子废弃物有效收集起来,是关系到电子废弃物管理和循环利用的重要环节.在我国建立良好的电子废弃物收集体系,应以市场经济和目前我国“城乡二元经济“为基础,建立具有收集主体多元化、收集方式多样化,收集途径多渠道等特点的电子废弃物收集体系.
