Herambiente Servizi Industriali


Page update 1 July 2019

 
    Tratment capacity
    60,000 t/year of which 8,000 t/year of hazardous waste.
    Waste accepted
    hazardous and non-hazardous special waste, in a muddy and powdery physical state. Waste from outside the region is also authorised.

    The plant consists of:

    • loading hopper;
    • conveyor belts;
    • mixer;
    • silos for storage of the reagents used in the process;
    • stabilised waste storage area.

    The waste fed into the plant has been previously checked in accordance with the applicable procedures for the storage of Herambiente Servizi Industriali in Via Usciana from which it comes.

    Stabilisation plant
    Industrial waste is treated in the stabilisation plant using a stabilisation and solidification process with hydraulic binders. In particular, waste such as shovellable sludge and dust is treated to obtain a material with chemical-physical requirements suitable for disposal. Stabilisation/solidification is obtained by fixing the pollutants (heavy metals) to the waste structures and significantly reducing the dissolution of these pollutants in the leachate. The stabilised waste thus obtained is stored in a dedicated area with an exhaust ventilation system, awaiting the required maturation, and then it is disposed of definitively, after analytical checks.
    The air drawn during the stabilisation and maturation process is treated by two-stage wet scrubbers.
