- Fundamental studies on liquid and solid slags
Research focusing on the physical, chemical, thermodynamic and structure properties of liquid and solid slags, such as viscosity, phase equilibria, interfacial properties, polymerisation degree, interactions between minerals and gels... It considers both experimental and characterisation studies, calculations and (nano-scale) modelling work.
- Hot-stage slag engineering, slag solidification, slag conditioning, internal reuse
Research focusing on:
- The hot-stage engineering of slags and the solidification procedures with the aim to improve the slag valorisation opportunities. It includes lab or pilot scale studies dealing with the effect of additions at high temperature and/or of the cooling procedures on the properties of the liquid and/or solid slag. Studies dealing with the mineralogy and leaching behaviour of the slag are included in this.
- Phenomena and reactions during weathering of metallurgical slags, and the effect of weathering and the weathering conditions on the slag properties and the slag valorisation opportunities.
- The recycling of slag within metallurgical plants and the evaluation of this procedure.
- Slag cleaning and metal recovery
Research focussing on:
- Clean slag production for added-value application of metallurgical slags and/or other industrial residues. This includes slag design for zero waste metallurgy, deep reduction of ferrous and non-ferrous slags, plasma fuming, removal of harmful component from slags.
- Recovery of base metals, rare earth and precious metals from industrial wastes and/or secondary resources. In particular, research that highlights metal recovery through both metallurgical processes (e.g. pyro-, hydro- and electro-metallurgy), and mineral processing (e.g. magnetic separation, gravity separation, flotation separation)
- Production, properties and performance of slag-based products
Research focusing on the conception, development, optimisation or understanding of innovative production processes that promote slag valorisation and the generation of slag-based products. It also includes studies addressing the effect of the production process on the desired properties of existing products or the evaluation of their performance at any stage of development.
- Process development for sustainable technologies
Research on slags compatible with the UN Sustainable Development Goals No. 12 (“Ensure sustainable consumption and production patterns) and 13 (“Take urgent action to combat climate change and its impacts”) and/or the European Green Deal. In particular, research that promotes and emphasises novel ideas and/or technologies focusing on sustainable slag management, lower carbon emissions, and more efficient use of resources.
- Industrial case studies on slag/residue valorisation
Research at pilot-plant or industrial level (Technology readiness level 5 or higher) that aims at upscaling, implementing, and/or optimising slag valorisation. Pre-and feasibility studies highlighting evaluation from a technical perspective are also welcome, as well as technical reports of lessons learned from full-scale implementations.
- Environmental and economic analysis
Research which focuses on environmental and economic analysis of slag valorisation, metals and heat recovery. In particular, studies that use life cycle assessment, life cycle costing, cost-benefits analysis and other assessment tools to evaluate the environmental and economic trade-off the costs of the recycling processes and the benefits of materials and energy recovery.
- Policy and regulations
Research focusing on how policy and regulation can boost for valorisation of slag and other residues from high-temperature processes. It includes studies from public bodies or private sector, using real case studies or prediction models to analyses the consequences of policy and regulations on the environmental performance of high-temperature industry.
