"Refractory recycling: A contribution to raw material, energy and climate efficiency in high-temperature processes"

Around the world, up to 28 million tonnes of used refractory materials are produced every year. The majority of used refractory materials are primarily used for other purposes, e.g. as aggregates for road construction (downcycling) or deposited in landfill sites. The recycling of these materials has played a subordinate role to date. For ecological reasons and due to increased landfill costs, an increased need for research into the utilisation of recycled refractories has been identified in recent years.

The Research Training Group GRK 2802 has set itself the goal of researching high-quality reutilisation options for used refractory materials. The Research Training Group aims to develop basic scientific findings that enable both the recycling (reuse in similar high-temperature materials) and upcycling (material upgrading) of refractory materials in metallurgical processes.

Objectives

  • Interdisciplinary, structured training of doctoral students in the field of recycling and upcycling of refractory materials
  • Research into a new generation of coarse-grained high-temperature materials based on recycled refractories with special functional properties for high-temperature metallurgical processes

Core ideas

Core idea I: Recycling

  • Refractories recyclates for novel refractory materials using environmentally friendly binders (resin-free, pitch-free)
  • Application: Lining material for steel ladles

Core idea II: Upcycling

  • Refractories recyclates for novel composite materials
  • Application: Electrode material for aluminium smelting flux electrolysis
