The Hürth plant has the yearly capacity to process up to 80,000 tonnes and the Hamburg plant around 30,000 tonnes of street cleaning material, road shoulder planings and topsoil with the waste code numbers 20 03 03, 17 05 04 and 19 12 09. Various screening techniques are used in the processing, in the course of which three fractions are obtained.
- Fine fraction: mostly mineral
- Medium fraction: mainly branches, leaves with mineral adhesions, grass and roots
- Coarse fraction: mainly household waste-like components
While the fine fraction can be used in earthworks or in landfill construction, e.g. as recultivation soil or for profiling, the medium fraction is usually composted. Portions that are not suitable for composting are thermally treated – as is the coarse fraction.
