Massafra | Tarent - Italy
  • System description: Production of densifi ed RDF
  • Waste processed: Mixed municipal solid waste
  • Plant capacity: 93,600 t/year

For this plant, Ecomaster has designed the general treatment process, followed up some purchases and assisted the Client during installation and start-up. This system treats special non-hazardous waste, as well as the light fraction deriving from the sorting of municipal solid waste. First of all, the material is treated by a low-speed shredder loaded by means of a wheel loader, after waste that cannot be shredded has been separated. A magnetic separator sorts out ferrous metals; then two ballistic separators separate heavy inerts from the material to be used for RDF production. Each double-stage ballistic separator is equipped with slanted oscillating elements that move the light fraction forward. This material, containing a high quantity of combustible components, is then processed by two secondary shredders working in parallel. The shredders have one single rotor with a low rotation speed and a grate to control the product size. After further ferrous separation, four densifiers work in parallel. Pressure rolls push RDF through the die holes, thus ensuring material densification as well as size control. Densified RDF is then conveyed to a system loading trucks that take the material to the neighboring resource recovery power station. This facility also allows densifying finished RDF coming as bales.
