Towards a circularity indicator to assess products' materials and lifetime: In-use occupation

摘要

Slowing and closing loop strategies have the ultimate goal of avoiding materials' losses, hibernation, and emissions, therefore all kind of actions that hamper useful applications. Consequently, there is a need to develop indicators that can deal with mass and time. A way to indicate circularity is by measuring the in-use occupation of resources, that is, keeping materials in a useful state, avoiding dissipation, and adverse effects, such as burden transfer. The objective of this work is to advance in-use occupation as an indicator for the circularity of products; therefore, we schematically present a framework and parameters for such indicators.
