Goals of recycling bottom ash
Convert ash into valuable raw materials
1. Recovery of (non ferrous) metals down to 0,5 mm
2. Reuse ash minerals in alternative markets (NL – Greendeal - non IBC)
3. Decrease carbon footprint for WtE facilities
Technical challenges:
• Wet de-slagging at WtE facility
– This makes the ash stick together tightly
– Embedded fine NF particles are hidden in clogged minerals
• Separating heavy / light non ferro’s:
– Conventional sink-float operations are not build for particle sizes < 10 mm
• Practical knowledge and experience (how does theory work out in practice ?)
• Discharge of ash residue that is qualified as waste (EURAL Code 19.12.03)
Financial challenges:
• Optimise the balance between costs (CAPEX and OPEX) and revenues related with bottom ash recycling
• Make use of low cost technologies and create the highest possible value from recovered materials

Technical challenges
Knowledge
• Theoretical knowledge of the Delft University of Technology
• Experience of current annual treatment of > 2,5 million tons of bottom ash
• Characterisation of specific bottom ash flow:
– Inashc0 Laboratory:
• Moisture content
• Particle size distribution
• NF contents (heavy and light NF characterisation)
– Operatability test
