Plant description
The pre-selection plant of mixed waste is divided on four parallel lines, each of which comprises a pre-selection stage consisting of a coarse shredding, a primary screening, a separation of ferrous and non-ferrous metals and a pressing of the coarse material, and a refining step of the organic waste consisting of a secondary screening, with the production of an underscreen to be biologically stabilized and an overscreen to start to recovery with ballistic and infrared separation of recyclable materials. The system doesn’t provide for the use of personnel for the sorting operations, which is conducted exclusively automaticly and managed by the operator from the control room. From the undifferentiated M.S.W. the process allows the separation of the following: plastics to start to recover; iron and aluminum to be recycled by carrying foundry; organic material to be stabilized for covering landfills or environmental remediation; material with high calorific value and pressed into bales for disposal in landfill or for recovery as fuel in incinerators.
The factory body is constantly kept under negative pressure in order to ensure the health of the workplace. The air handling system is constituted by a scrubber (type washing tower) and a biofilter capable of returning the air in the atmosphere in accordance with the most stringent limits of law.
It is also in place an implementation phase aimed at the refining of the screening material coming from the primary and secondary screening and waste of the ballistic and optical separation; this material is the so-called RDF (Refuse Derived Fuel), “product” that will be inserted in the chain of the fuels used in cement plants, power electrical stations, etc.
