Landfill for non-hazardous, municipal and special waste similar to municipal waste

The landfill site is located in the far south of the municipality, in a hillside gullied area at an altitude of between 150 and 230 m above sea level and 9 km from the city.

It is located at the centre of the municipalities served, which form the Hera Group catchment area. The municipalities in question are municipalities in the Province of Bologna (Imola area), in the Province of Ravenna (Faenza area) and in the Province of Florence (Firenzuola, Marradi and Palazzuolo sul Senio).

    Landfill type
    Non-hazardous municipal waste, special waste similar to municipal waste and non-toxic/non-harmful sludge.
    Operational status
    Currently suspended the cultivation of the elevation of the third batch (375,000 ton)
    Permitted acceptable waste
    250,000 t/year of waste for disposal and 50,000 t/year of recovered waste relating to cell III under operational management
    Overall capacity
    • 4,175,000 m, equivalent to 3,758,000 tonnes of waste, corresponding to cells 1 and 2 which have reached maximum capacity
    • 2,094,000 m, equivalent to 1,500,000 tonnes of waste for disposal (relating to cell 3, which became operation in August 2010)
    Placement type
    5-metre thick layers

    Landfill waste must meet and comply with the requirements of the operational management plan approved by the Province.
    The handling and storage activities aim to guarantee the placement of waste with minimal environmental impact, creating overlapping, compacted layers with the waste to maximise the density of the waste. At the same time, the accumulated deposit must be maintained highly stable and the infiltration of rainwater, and thus the formation of leachate and the penetration of insects and other animals into the landfill site, must be minimised.
    At the end of each working day the waste is covered with different materials, such as (from top to bottom):

    • activated carbon liners for odour abatement;
    • excavation soil or other inert material;
    • stabilised organic fraction resulting from the processing of the municipal waste.

    The leachate collected by the special networks is transported to a system of on-site impoundment basins and from there, through a dedicated pipe for treatment at the Santerno purification plant in Imola; these basins present a bottom sealing system capable of preventing all possible subsoil infiltrations. Alternatively, the leachate may be transported to authorised treatment plants.

    The captured biogas is used to generate electricity; the plant consists of two eight-stroke engines with overall generation of 2,130 kWe.
    In emergency situations or during scheduled down-time, the auxiliary biogas combustion system comprising a high-temperature gas flaring with a flow rate of 1,500 Nm3/hr is automatically activated.

    As regards the potential impact of the operation on the quality of the soil and subsoil, in accordance with the provisions of Legislative Decree 36/03, the scheduled sealing programme for the operational cell is such as to guarantee a perfect seal against the leachate, thus preventing it from contaminating the underlying soil layers.

    Environmental restoration takes place on conclusion of placement, following an initial settlement phase and envisages the seeding of the slopes and the planting of trees and shrubs through an environmental insertion project that will result in the morphological remodelling of the slope in line with the surrounding area. As regards the soil, plans for the planting of trees and shrubs will contribute towards mitigating the impact of the landfill once full capacity has been reached.
    Part of that final layout has already been completed, while giving priority to the perimeter area of the site and the areas along Via Pediano.

    The envisaged monitoring plan thus aims to check:

    • atmospheric emissions originating from the landfill site, from powders and exhaust gas resulting from the transit of motor vehicles and from the handling of waste;
    • noise emissions;
    • the exhaust, connected by direct piping, to the Santerno purification plant in Imola, authorised by the current IEA;
    • the characteristics of the leachate;
    • the quality of surface water bodies.
