The plant designed was developed in accordance to a public tender for the construction of an integrated system for the M.S.W. management in the Municipality of Messina (CIG 55388378E1), which was issued by the Commissioner for the Waste Emergency in Sicily (O.P.C.M. 9/7/2010 n. 3887 – D.L. n. 43/2013). The plant lay-out provides one mechanical treatment line for the screening of M.S.W. with a capacity of 32.1 ton/hour, 12 hours/day, which is divided as the following: a wide area for the storage of the incoming wastes, a shredding and a double-stage screening (with holes from 130 to 80 mm). This to separate the following materials: i) oversize fraction >130 mm by which nonferrous (e.g. aluminium cans) and ferrous materials can be separated; ii) oversize fraction 80÷130 mm, by which ferrous materials can be separated; iii) underscreen fraction <80 mm, which must be processed with biological treatment.
The designed layout provides the construction of a landfill with a capacity of 270.000 m³ which will be used for the final disposal of the fraction deriving from the mechanical treatment and also the construction of a leachate treatment system, which is constituted by an ultrafiltration section and 4 steps of reverse osmosis for the complete purification of the wastewater. The underscreen fraction deriving from the mechanical treatment will be processed within aerobic biological tunnel, which are closed and air forced with blowers, in order to obtain stable and dry materials which can be recovered or directed to final disposal.
The buildings will be kept in constant depression in order to ensure the health of workers; the air is recirculated within the aerobic tunnels to facilitate the process. At last the exhaust air will be treated with two scrubbers and a biofilter before the emission into the atmosphere, within law limits.
