Legal and environmental bottlenecks and opportunities for slag-based products valorisation

  • Standardisation of slag-based products: Need for internationally accepted standards for slag-based construction materials.
  • Recyclability of slag-based construction materials: Need to understand the long-term behaviour of slag-based materials (recyclability second life cycle, possible re-mobilisation of heavy metals)
  • Carbon footprint of slag-based products, potential as carbon sinks: Understand the environmental balance or carbon footprint (LCA or else) of slag-based material compared to traditional construction materials. Understand their capacity to act as carbon sink (e.g. carbonation)
  • By-product or waste? Need to define the legal status of industrial slag, to strengthen their position and their value in the market.

Innovation and entrepreneurship in the raw materials sector

  • Start-up and innovative ideas
  • New business model
  • Market trends, analyses and forecasts
  • Case studies of products in the market

Programme Overview

Plenary lectures will be given by invited specialists and/or high level representatives of the key institutes in this field (academia, industry and entrepreneurship). The invited scientific lectures cover each a specific topic in a relatively detailed way.

In 7 thematic sessions, participants will be given the opportunity to present their work to the audience. Participants submitting an abstract can indicate whether they would like to be considered as poster or as oral presenters. After revision and acceptance of the abstract by the Scientific Committee, they will be scheduled by the Organizing Committee in the appropriate session.
