Process concept for Melt-Recrystallisation

RekCarb – Upcycle of carbon containing residuals and by-products through recrystallisation in molten metals

Initial Situation:

  • Many carbon containing residuals are yet either burned or landfilled
  • The chemical potential of carbon containing residuals often remains unused, since economically feasible processes for the recycling of carbon containing residuals are not established.
  • Examples for C-containing residuals or by-products:
    • Polymeric scrap
    • Carbon black produced during methane-pyrolysis


  • Development of anew process concept for the manufacturing of carbon nano materials
  • Upcycle of residuals to Graphene-Nano-Platelets (GNP)


  • Conceptual design and construction of an experimental setup for the Melt-Recrystallisation
  • Investigation of optimal conditions for recrystallisation of Carbon
    • Composition of the fusible alloy
    • Temperature control
    • Influence of feedstock material
  • Implementation of a circular process:
    • Injection of carbon containing material as powder or granulate
    • Conceptual design for the separation of the carbon nano material from the melt surface
  • Investigation of the chemical composition and morphology of the carbon nano material
