supersort®

supersort® and supersort®fine use dry-mechanical process for the conditioning of municipal solid waste incinerator bottom ash. It recovers metals and organics and bring them back into the resource cycle.

supersort® is a dry mechanical recycling plant and reaches with up-to-date technologies a high recovery of valuable products such as ferrous and non-ferrous metals, stainless steel and Cu-Fe 'meatballs' from MSWI bottom ash. Developed by DHZ, supersort®fine is an innovative process for the treatment of MSWI bottom ash particles < 3 mm. The technology enables the recovery of metals out of the fine fraction that usually is directly landfilled. Given that the sieves in standard Screening machines tend to clog with damp material, supersort®fine uses a different technique. The supersort®fine acceleration machine achieves a coarse fraction with a higher percentage of heavy metals than in the primary bottom ash. The coarse fraction runs through an eddy current separator and ends up as a high-grade, highly valuable metal concentrate. Together with a Swiss equipment manufacturer, DHZ recently embarked on the commercialisation of its supersort®fine pss machine.

The generated non-ferrous metal concentrates are cleaned and sortetd to pure non-ferrous metals in the plant supersort®metal in Oberglatt.

The mineral fraction with a low metal content is landfilled in compliance with Swiss regulations. The recycling plant processes over 120 000 tons of bottom ash per year. A major advantage for the legal disposal of the mineral residue fraction and especially for logistics is the plant’s convenient location next to the Häuli landfill in Lufingen.
