Pre - Processing

MSW travels its journey from being waste to finally transforming into RDF (Refused derived fuel) in Pre- processing system. MSW is transferred to Pre-processing system (PPS) after resting for 4-5 days in the pit through grab cranes. MSW gets passes through segregation machinery installed in PPS. Machinery consists of Hoppers, Ram feeder, Ballistic separators, Shredders, Conveyer belts, Magnetic separators & Screen. MSW travels is fed in hopper by Grab Crane and Ram Feeder feed it to ballistic separator. Inside Ballistic separators MSW gets segregated according to its size based on principle of density separation. Metals are separated by a magnetic separator. Shredder shred the oversize material


The PPS results into 3 main products

  1. Below 10 mm size organic particle is taken to the compost for further processing
  2. Stone, Glasses which are termed as inert are sent for land filling
  3. Waste between 10 mm to 200 mm of size is considered as Refused derived fuel (RDF). RDF is the desired feed for the boilers which will be used for generation of energy
