Query: Thermodynamical Material Networks for Modeling, Planning and Control of
  Circular Material Flows   Waste production, carbon dioxide atmospheric accumulation and dependence on
finite natural resources are expressions of the unsustainability of the current
industrial networks that supply fuels, energy and manufacturing products. In
particular, circular manufacturing supply chains and carbon control networks
are urgently needed. To model and design these and, in general, any material
networks, we propose to generalize the approach used for traditional networks
such as water and thermal power systems using compartmental dynamical systems
thermodynamics, graph theory and the force-voltage analogy. The generalized
modeling methodology is explained, then challenges and future research
directions are discussed. We hope this paper inspires to use dynamical systems
and control, which are typically techniques used for industrial automation, for
closing material flows, which is an issue of primary concern in industrial
ecology and circular economy.
