Purpose of Review

The aim of this study was to analyze the differences and similarities between the concepts circular economy (CE) and cascading utilization (CU) and the interactions between these concepts. The method chosen for this study was a qualitative content analysis, which was conducted on academic CU publications that appeared between 1990 and 2016. To identify connections between CU and CE, the findings of this study are compared to the results of a recent review on CE.

Recent Findings

From the perspective of the broader goals of CE and CU, both concepts promise to increase resource efficiency by supporting the multiple use of a resource. Research conducted on both concepts has included analyses of the environmental impacts of the CU or CE systems and descriptions of frameworks and tools used to develop cascade chains or measure the circularity of a given resource. Even though the concepts have many similarities, the research has mostly been conducted independently, and the number of connections between the two concepts is surprisingly low.

Summary

In general, the results of the analysis supported the hypothesis that CU and CE have many parallels and similarities. The CU concept addresses primarily resource management whereas CE provides a more holistic approach. Practically, the publications on CE include considerations of many kinds of resources, whereas publications on CU include a stronger focus on bio-based materials. Despite these differences, CU was shown to clearly fit into the CE concept in that it provides a specific focus on the utilization possibilities (e.g., reuse, recycling, and up-cycling) of a given resource. The term CU may be used whenever one or more of these measures are used.

木材的级联利用:循环经济的问题?

审查目的

这项研究的目的是分析循环经济(CE)和级联利用率(CU)之间的异同,以及这些概念之间的相互作用。本研究选择的方法是定性内容分析,该分析是对1990年至2016年间发表的CU学术论文进行的。为了确定CU与CE之间的联系,将本研究的发现与近期对CE的评论结果进行比较。

最近的发现

从CE和CU的更广泛目标的角度来看,这两个概念都承诺通过支持资源的多次使用来提高资源效率。在这两个概念上进行的研究包括对CU或CE系统对环境的影响进行分析,并描述用于开发级联链或衡量给定资源循环性的框架和工具。尽管这些概念有很多相似之处,但研究大多是独立进行的,并且两个概念之间的联系数量非常少。

概要

通常,分析结果支持CU和CE具有许多相似之处的假设。CU概念主要解决资源管理问题,而CE提供更全面的方法。实际上,关于CE的出版物包括对多种资源的考虑,而关于CU的出版物则更加关注生物基材料。尽管存在这些差异,但已证明CU明显适合CE概念,因为它特别关注给定资源的利用可能性(例如,重用,回收和向上循环)。只要使用这些措施中的一项或多项,就可以使用术语CU。
