CIC energiGUNE, the coordinator of the RESLAG project, hosted the 1st Workshop of the European project at Vitoria-Gasteiz (Spain) on the 14th and 15th of November. More than 60 people attended the Workshop from 11 countries, and 14 technical talks and 10 posters were presented.
The Workshop brought together an interdisciplinary panel to present RESLAG project results and current efforts, challenges and future directions for eco-innovation and circular economy initiatives in the field of waste recovery. It included talks from institutions (EUROSLAG, SPIRE), companies (Optimum Cement, Renotech, Life Cycle Engineering, FEHS, Max Aicher) and research centers and universities (CIC energiGUNE, IK4-Azterlan, DLR, ENEA, VTT, Fraunhofer IWKS, Tecnalia, SINTEF). The next project Workshop will be hosted by the project partner MASEN in Morocco on 2019.
The RESLAG project is aligned with the challenges outlined in the call WASTE-1-2014: Moving towards a circular economy through industrial symbiosis of the European Horizon 2020 programme. The main aim of RESLAG project is to prove that there are industrial sectors able to make an effective use of the 2.9 Mt/y of landfilled steel slag, if properly supported by the right technologies. In making this proof, the RESLAG project is also proving that there are other very important environmental benefits coming from an active use of the slag in industrial processes.
To achieve this ambitious goal, four demonstration pilot systems have been built within the RESLAG project targeting the following industrial applications:
- High value and critical metal extraction from slag. The recovery of metallic raw materials, such as Cr, Mn and others is one of the European Commission priorities for better exploitation of the available resources.
- Waste heat recovery. A cost effective heat recovery concept to capture and store the heat content of the exhaust gases from the electric arc furnace in the steelworks is proposed by using the steel slag as heat storage media.
- Heat storage systems for the concentrated solar power (CSP) industry. The use of steel slag using molten salts and air as heat transfer fluids is being tested to promote greener and cost-effective storage solutions for the CSP.
- Production of innovative refractory ceramic compounds. The inclusion of the steel slag as an aggregate in innovative refractory recipes will decrease the overall cost of the produced material without any interference on the required material performance.
All these demonstrations have been led by a well-balanced project consortium conformed by leading industries and also research centers and universities involved in the European material, energetic efficiency and technological scenario.
