The Centre is authorised to receive, store and treat hazardous and non-hazardous municipal and special waste.

Page updated 26 August 2015

    Maximum instantaneous storage capacity
    3,210 t (590 t in tanks for liquid waste, 560 t in tanks for sludge or solid waste, 150 t in tanks for powdery solid waste)
    Treatment capacity
    A maximum of 25,000 t/year of HAZARDOUS waste may be pre-treated. There are no limitations placed on non-hazardous waste
    Types of waste accepted
    Hazardous and non-hazardous municipal and special waste. Waste from outside the region is also accepted, but priority is given to local and regional waste

    The plant centre has the following sections:

    • storage area;
    • processing rooms;
    • grinding plant;
    • neutralisation plant.

    Specific waste control procedures are implemented both during the definition of customer contracts (the "certification" stage) and on acceptance of waste at the Centre.
    Correspondence between the quality of the incoming waste and the respective certification is verified by means of regular visual and analytical controls and through spot checks, with the collection of waste samples.
    Following the control phase, the waste is labelled and stored in the Centre's facilities, while waiting to be treated, re-packaged and sent to external disposal plants.

    Waste in small drums or containers is stored in separate departments depending on the different hazard features and the flash point so as to ensure maximum safety of the entire area. The various types of waste are stored in suitable containers (metal tanks, silos and reservoirs) and all handling (unloading and transfers) is carried out using steel pipes and pumps, while the gaseous fumes produced are channelled to an activated carbon purification system.
    Waste accepted for storage can be sent for pre-treatments such as:

    • re-packaging of solid waste including powdery waste;
    • re-packaging of liquid waste;
    • re-packaging of two-phase waste;
    • mixing and homogenising;
    • thickening;
    • waste compaction (in a permanent grinding plant).

    All treatments take place in bottom-lined, confined and sunken facilities, with de-dusting of the aspiration air and subsequent transit in activated carbon filters.
    Suitable sensors detect the presence of any trace of flammable gases.

    Industrial waste is treated in the neutralisation plant using a stabilisation and solidification process using hydraulic binders. Specifically, waste such as semi-solid sludge and fines are treated so as to obtain a material with the physicochemical characteristics required for its disposal. The stabilisation/solidification process is achieved by binding pollutants (heavy metals) to the waste structures and significantly reducing the dissolution of these pollutants in the waste water produced. The neutralised waste thus obtained is subsequently stored in a dedicated part of the landfill until it has reached the required maturity and is subsequently definitively disposed of following analytical checks.

    The volumetric reduction of hazardous and non-hazardous waste with a solid or pitchy consistency takes place in a confined, bottom-lined building before final disposal. Contaminated empty packaging may also be treated in this manner. The grinder is fed by a fixed, orange peel grab device that is remote controlled by an operator from an elevated station that allows visual control, and is isolated from the surrounding environment.
    The facilities are equipped with aspiration tools, flammable gas sensors and a specific fire-fighting and foaming system.

    Due to the hazardous substances potentially present in incoming waste and the relative maximum quantities permitted, the Centre is a facility at risk of major accidents and is therefore subject to the provisions of Articles 6 (notification system), 7 (major accident prevention policy and safety management system) and 8 (safety report) of Legislative Decree 334/1999 and subsequent amendments. As a result, it has put into place a specific safety management system to monitor the danger of major accidents, in accordance with the provisions of Ministerial Decree 09/08/2000 and, as part of its activities for the implementation of that System, it has also defined a Major Accident Prevention Policy.
