Abstract In 2013 approximately 110 Mt "waste" slag was produced worldwide at temperatures of 1650 oC containing ~25% of FeO , making it a potential source of energy and raw material. This work aims to combine and implement two concepts developed in the laboratory to industrial steelmaking. The first is to convert the thermal heat of the slag into hydrogen (from water),which can be used to lower the in-house C footprint or exported externally as a fuel. Secondly the valuable metal oxide are recovered for in-house re-use and lower raw materials usage or exported for other purposes. Both concepts are based on controlling the gas atmosphere. The project aims to at developing fundamental knowledge on the slag structure and its evolution as function of gas atmosphere and temperature (WP1 and WP2) and based thereupon, design and build an industrial test-reactor for carrying out the process (WP3). If implemented worldwide, it is envisaged that the process, if successful, could save over $3,300 M based on the BOS steel produced in 2013. In addition, the recovery of heat and valuable chemicals contributes to a more green and energy and raw-material resilient steel industry. The Warwick group will lead on the development of the integrated heat-materials recovery process, completing scale-uptrials to recover both the thermal energy (producing syngas fuel) and valuable metal elements in oxide forms (e.g. Fe3O4and Fe2MnO4). They will also be involved in WP2 - providing support for materials recovery and WP3 - advice for the pilot plant trials
