    Challenge the future

    Delft University of Technology

    Post-consumer steel scrap Technical developments and economic feasibility Resources & Recycling

  • 2 Upgrading post-consumer steel scrap

    Resources & Recycling at Delft

    Create innovations in recycling that

    add value from all perspectives:

    social, environmental and

    industrial-economic

    Mission

  • 3 Upgrading post-consumer steel scrap

    Steel scrap from IBA High contamination levels > low/variable price

    Double gain from cleaning: sales of Cu and increased value of steel

  • 4 Upgrading post-consumer steel scrap

    Environmental gain recycle steel CO2-emission

    Recovering fine & midsized steel from 1 ton of IBA saves 30-50 kg of CO2-emission

  • 5 Upgrading post-consumer steel scrap

    Steel scrap upgrading CSM technology

    *Installation at Sluiskil, the Netherlands (Resteel, 50 t/h)

    IBA 1 2-20 0.7% Cu, 1% batteries, Phosphor, 0.1% S,

    10% sand/rust, 0.2% coarse stone, 0.1% cloth/plastic

    ELV 8-11 30-200 0,7% Cu, rubber, stainless, cast Al

    Recovery

    At 18 t/h of IBA scrap, six hand-pickers recover max. 50 mass% of the copper contaminants, at a (hand-picking) cost of about 6 €/t of IBA scrap
