The transition towards a circular economy has gained importance over the last years since the traditional linear take-make-dispose paradigm is not sustainable in the long term. Recently, thermodynamical material networks (TMNs) [1] have been proposed as an approach to re-design material flows based on the idea that any supply chain can be seen as a set of thermodynamic compartments that can be added, removed, modified or connected differently. In this paper, we develop several circularity indicators of TMNs using a graph-based formalism and demonstrate their calculation through examples. The paper source code is publicly available.
