Circular economy: From electronics

scrap to materials and energy Annual scrap production 20 – 50 Mt, annual growth rate 3 – 5 %

Currently treated in smelters, found from industrial countries

Plenty of scrap found from developing countries

Circular economy: From electronics scrap to

materials and energy

- Air blown CFB gasification (+BFB + Fixed Bed)

- Gas cooling to 350-500oC

- HCl removal: Ca(OH)2 + inherent Ca, Na, K

- Gas filtration (removal of ash, alkali metals, heavy metals)

- Fuels: Wheat straw, demolition wood, several qualities of SRF/RDF, industrial wastes, sewage sludge, plastic waste, Auto Shredder Residue, electronic scrap, etc.

WEEE

Bottom ash; bed material + metals

(=> metallurgical processing

Flexmet platform)

Fly as/Filter dust; unburnt carbon, metals,

chlorine, etc.

Metals removal using Flexmet platform

Cleaned fuel gas for energy
