Mechanical-biological processing plants

Main emphasis
  • Mechanical-biological treatment
  • Freeing and preparation of the raw material for subsequent sorting
  • Separation of recyclable materials such as metal, paper, cardboard, plastics, etc.
  • Separation of impurities such as PVC, aggregates, etc.
  • Production of substitute fuels according to customer specifications
  • Reduction of the material to be dumped

Process steps – mechanical-biological waste treatment – focus on RDF:

Mechanical pre-treatment
  • First crushing
  • Separation of ferrous metal
Biological treatment
  • Biological drying
Mechanical processing
  • Repeated shredding
  • Sifting/wind sifting
  • REDWAVE optical sorting for the separation of PVC
  • Recovery of residual ferrous and non-ferrous metals


  • Energy recovery
  • Material recovery
  • Landfilling of the inert
Practical example of an MBT plant
  1. Pre-treatment
  2. Biological drying
  3. Screening, classification
  4. Sorting
  5. Storage / loading

Highly efficient sorting and excellent separation results thanks to waste drying.


High degree of automation

  • Fully automated loading and unloading processes using cranes
  • Efficient ventilation circuit minimises the amount of exhaust air
  • Fast biological drying process (6 days) – reduction of the moisture content from 40% to <20%

Highly efficient sorting and secure workplaces

  • Excellent separation results thanks to waste drying
  • Completely closed and ventilated facility
  • Clean and safe work environment
  • Proven and reliable sorting process with system availability > 90%
  • Dry and storable
  • High calorific value (approx. 15 MJ/kg)
  • Homogeneous fuel, very low content of contaminants
  • Positive carbon balance
  • Ferrous and non-ferrous metals as commercial goods
  • Can be deposited according to the German OJ-VO


Try the machines yourself

The REDWAVE test and innovation centre, newly built in 2020, was not only built for continuous improvement and advancement in research and development; primarily it is there for our customers. Our test centre is always available for sorting tests.
