Due to ever increasing landfill costs, fewer landfill opportunities and the need to reduce carbon emissions, more waste processing companies are looking to optimize recyclable material extraction and maximize refuse derived fuel (RDF) recovery.

Mechanical biological treatment (MBT) companies can increase recycling opportunities when using M&J Preshredders. By combining waste PreShredders with waste FineShredders, a perfect RDF can be produced, thus ensuring a maximum recovery of material.

Waste type

  • Household (MSW)

Especially well suited for MBT plants

Advantage in Metso EtaPreShred

  • Open cutting table reduces wear to the bare minimum
  • Bi-directional shredding results in a consistent flow of shredded material onto downstream conveyors
  • Asynchronous shredding keeps waste constantly moving, thus improving shredding efficiency. With our aggressive knife design, no pushing device is required
  • Central lubricating system is standard on all machines
  • Power pack and cutting table that can be mounted separately to keep more delicate components away from dust
  • Automatic reversal, if knives encounter large or tough steel or cement objects
  • Intelligent shredding routines automatically adapt to processed material characteristics.
  • The PLC control system is equipped with six standard programs, including two that can be individually programmed
  • Hardox steel used in all parts of the cutting table exposed to wear
  • Bi-directional shredding with equal speed and torque reduces wear and improves shredding capability and capacity
