MSWI bottom ash

Non-ferrous metal concentrates with a grain size of 0 – 100 mm from different recycling plants

Shredder residues: light and heavy fraction

Other metal-containing wastes streams


supersort®technology generates pure metal- and plastics-fractions. Particles size and quality of products can be changed upon customer requests.

Thanks to a continuous process monitoring, we can guarantee a high and constant product quality.

Use the potentials

The supersort®technology concept is based on an ambitious DHZ engineering programme and a combination of in-house research, experience in different recycling technologies and state-of-the-art techniques used.
In a close co-operation with specialists and equipment manufacturers the concept was converted step by step into reality. The supersort®technology plants are running with great success and are recovering metals larger than 0.5 mm.


Our service

A lot of disposal contractors dispose too much metal in their landfills and pollute the seepage water and the environment. On the other hand the recovered metals can be sold for a good price. Using the right technology an additional 1% of non-ferrous metals can be recovers in the grain size form 0 – 3 mm (depending on input-material and bottom ash quality). With a prospective co-operation you can use this potential too. We offer our skills in the following domains:

  • Plant conception

  • Planning and designing

  • Construction and launch of the plant

  • Designing a suitable logistics concept
