In order to operate an integrated management of municipal solid waste, the designed
plant is aimed to both maximize the recovery of materials and prepare a fuel from waste,
the refuse-derived-fuel (RDF). The maximum treatment capacity amounts to 300.000 t/y.
The machinery layout is arranged in three lines for the mechanical sorting of municipal
waste, having a total treatment capacity of 365 t/d; the system comprises: a wide
storage area for incoming waste, a hopper and two pre-shredders that make the material
dimensions adequate for the following sorting phases (dimensions less than 200 mm)
and two vibrating screens to separate two flows of materials, the underscreen one, that

is smaller than 30 mm, and the upper screen one, from which ferrous metals and non-
ferrous metals (e.g. aluminum cans) are also separated. The upper screen fraction is

also subjected to air separation, optical separation and manual sorting in order to select
plastics for recycling (PE, PET, etc.). Lastly, the driest fraction separated from the incoming
waste is sent to a fine shredding section for producing the RDF, a high-calorific-value fuel,
which is baled and sent to thermal plants. A fourth line, consisting of a rotating screen, is
also set up to treat the roadside waste from the urban roads weeping activities.
The factory shed is constantly kept under negative pressure in order to ensure the health
of the workplace. The air treatment system is constituted by a wet scrubber system.
