Abstract

Measuring circularity is crucial to identify the status quo, set targets, monitor performance, and take action to pursue circular economy efforts. Regulators increasingly require companies to use and disclose recycled content in new products. However, calculating recycled content from closed loops in products is challenging and, so far, has not yet been implemented sufficiently in existing circularity indicators. Our study’s contribution consists of three parts: First, we conducted a literature review of existing indicators. Second, we developed the new Product-oriented Closed-loop Material Indicator (PCMI), which includes a detailed calculation method for a product’s closed-loop recycled content. Third, we applied the PCMI in an illustrative case study of recycled steel in cars. We show that the PCMI is comprehensive, versatile, and scalable. Thus, the PCMI provides the foundation to accurately measure the closed-loop recycled content in products, allowing companies and policymakers to steer towards higher levels of circularity.

期刊介绍： The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns. Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
