This paper presents a new assessment method, which is able to determine the practicality of opportunities to reuse wastes. In this study, the term--reuse has much wider concepts than simply recycling to a process. In other words, reuse in this case can include recycling, utilisation as a raw material for other processes, and particularly transformation of the waste to low or preferably high value added products. Preliminary opportunities for the reuse of a waste can be generated by various methods such as brainstorming, desk research, consultation with industrial and academic contacts, and the like. In this work, each preliminary solution is then assessed according to three different categories--technical, economic, and environmental and regulatory, in order to determine the viability for reuse. The responses of nine collaborating companies to questionnaires pertaining to the three categories were used to set up feasible boundaries of each category in terms of the reuse of their wastes. Based on the replies, lower bounds for each category were determined, and then the preliminary solutions generated were ranked. The approach was applied to several industrial examples. The ranking of the high-dimensional information was aided by visual representation on a parallel coordinate graphic plot. Although the selection or rejection of an opportunity was highly dependent on the boundaries obtained, the approach proposed could provide a useful guideline to decision-makers for selection/rejection of the reuse opportunities available.
本文提出了一种新的评估方法，该方法能够确定废物再利用机会的实用性。在本研究中，“再利用”一词的概念比简单地回收至某一过程更为宽泛。换句话说，在此情况下，再利用可以包括回收、用作其他过程的原材料，特别是将废物转化为低附加值或高附加值产品。废物再利用的初步机会可以通过各种方法产生，如头脑风暴、案头研究、与工业界和学术界人士协商等。在这项工作中，然后根据技术、经济、环境和监管这三个不同类别对每个初步解决方案进行评估，以确定再利用的可行性。九家合作公司对与这三个类别相关的问卷的回复被用于确定每个类别在其废物再利用方面的可行边界。根据回复确定每个类别的下限，然后对产生的初步解决方案进行排名。该方法应用于几个工业实例。通过在平行坐标图上的可视化表示辅助对高维信息进行排名。尽管机会的选择或拒绝高度依赖于所获得的边界，但所提出的方法可为决策者选择/拒绝可用的再利用机会提供有用的指导。
