In view of the increasing scarcity of primary resources during stagnating material consumption there are approaches needed for optimizing value chains, waste prevention and recovery of secondary raw materials. The concept of circular economy tackles this issue by including all sectors of the industry to effectively close the loop of material flows. Within the framework of project :metabolon the „network circular economy“ aims to bring together key players from the fields of research, industry and politics to bundle isolated efforts and harness synergies from cooperative exchange.

Coming from the waste management industry the network endeavours in connecting partners along the entire value chain from product design to waste disposal. For this purpose, material flows with urgent action required are identified and measures for their utilisation deducted. Through organisation of event formats, the actors are brought together so an open transfer of knowledge is assured. Within the formed work groups, impulses and strategies for research and support are developed. Initial focal points are the recycling of mineral residues and treatment of sewage sludge for phosphorus recovery as well as techno-economic analyses for the respective utilisation pathways.

The research community :metabolon under the sponsorship of the Bergische Abfallwirtschaftsverband (BAV) forms the core of the consortium in cooperation with

  • Unit of Technology of Fuels (TEER), RWTH Aachen University
  • Chair of Operations Management (OM), RWTH Aachen University
  • Institute for Infrastructure Water Resources Environment (IWARU), University of Applied Sciences Münster

The project is supported by representatives from initiatives and industry associations as advisory board for practicality of research approaches. The „network circular economy“ is funded by the European fund for regional developement and the Ministry for Environment, Agriculture, Conservation and Consumer Protection of the State of North Rhine-Westphalia.
