MBT Plant

Mechanical-Biological Treatment

  • Max. recovery of clean dry SRF & recyclables
  • Tailored systems for:
    • Coal co-firing
    • Advanced Waste-to-energy technologies (gasification)
  • Minimization of landfill disposal

Basic Principles – Mechanical Biological Waste Treatment – Focus RDF:

Mechanical Pre-treatment

  • Shredding
  • Ferrous separation

Biological treatment

  • biological drying

Mechanical Refinement

  • re-shredding
  • screening / windsifting
  • REDWAVE optical sorting to recover PVC
  • Recovery of remaining ferrous and non-ferrous metals
  • Energy recovery
  • Material recovery
  • Landfill of inerts

Mechanical Processing

Biodrying area (7,5 units)

Dust extraction / filter bag house

Reception area / waste bunker

High degree of process automation

  • Fully automated loading & unloading process operated by cranes
  • Efficient air circulation system leads to small amount of exhaust air
  • Fast biological drying process (6 days)
    Reduction of the moisture content from 40% down to <20%

High degree of sorting efficiency and safe working places

  • Due to the dried waste excellent separation results are obtained
  • Fully enclosed and ventilated equipment
  • Clean and safe working places
  • Proven and reliable sorting process with plant availability > 90%

RDF:

  • Dry and storable
  • High calorific value (approx. 15 MJ/kg)
  • Homogenous fuel, extremely low content of contaminants
  • Positive carbon footprint

Metals:

  • Ferrous and Non-ferrous metals (traded as a commodity)

Inerts:

  • Can be landfilled acc. to the German landfill directive Abl.-VO
