Understanding product circularity as “three-dimensional” could anchor the Circular Economy to common principles while affording its followers flexibility about how to measure it in their specific sectors and disciplines and within their organization's means. Inspired by a heuristic developed for the urban planning profession to cope with the inherent conflicts of Sustainable Development, this article argues that measuring product-level circularity should consider ways to achieve (1) high material recirculation, (2) high utilization, and (3) high endurance in products and service offerings. Achieving all three dimensions ensures that material flowing through the economy is recovered from prior use phases, that it is used intensely, and that it retains its value in spite of exogenous changes. The article argues further that these three dimensions ought to be measured and reported separately rather than as a composite metric and that certain applications will have opportunities to improve circularity through certain dimensions better than others. The article also explains how researchers at RISE (Research Institutes of Sweden AB) are working with industry and government partners to measure the three dimensions and how diverse actors interested in the Circular Economy can use the three dimensions to take the first steps in their transition to circularity.

立体产品圆度

将产品循环理解为“三维”可以将循环经济锚定在共同原则上，同时为其追随者提供灵活性，以便在其特定部门和学科以及组织的手段内对其进行衡量。受城市规划专业为应对可持续发展的内在冲突而开发的启发式方法的启发，本文认为衡量产品级循环性应考虑实现（1）高材料循环，（2）高利用率和（3）的方法。 ) 产品和服务的高耐久性。实现所有三个维度可确保流经经济体的材料从先前的使用阶段中恢复过来，得到大量使用，并且即使发生外生变化也能保持其价值。文章进一步认为，这三个维度应该单独衡量和报告，而不是作为一个综合指标，并且某些应用程序将有机会通过某些维度比其他维度更好地提高循环性。该文章还解释了 RISE（瑞典研究所 AB）的研究人员如何与行业和政府合作伙伴合作来衡量这三个维度，以及对循环经济感兴趣的不同参与者如何利用这三个维度迈出过渡到循环经济的第一步。圆。
