The landfill is located in the Bologna plains, approximately 26 km north of the provincial capital.
The landfill is more than 3 km from the residential centre of Malalbergo, 4 km from S. Venanzio di Galliera.
Two further ecological compensation areas (green woodland, wet meadow), with an overall capacity of 600,000 m, have been created outside the landfill, to the west and east respectively.

    Type of landfill type
    For non-hazardous waste: MSW
    Operational status
    Operational since 2002
    Envisaged saturation:
    2013
    Permitted acceptable waste
    for 2012, 105,000 t/year of acceptable waste, inclusive of 15% maximum stabilised organic fraction (SOF)
    Overall capacity
    1,270,600 m (long-term waste)
    Placement type
    4-metre thick layers

    Deliveries have ceased as capacity was reached in November 2013.
    When operational, waste was compacted and covered with earth, stabilised organic fraction and liners.

    Horizontal and vertical drainage using perforated pipes and draining materials. From the bottom that is subdivided into seven compartments (cells), each equipped with its own drainage and collection network, the leachate is channelled by gravity to a main pipe laid in a central, inspectable passage that runs along the entire longitudinal axis of the landfill and is accessible by both heads. The leachate is sent to a specific lifting plant and from there to storage tanks. The leachate is transported by tanker to authorised treatment plants.

    The biogas captured is used in the generation of electricity; the plant consists of three eight-stroke engines with overall generation of 2,300 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 1,000 Nm3/hr is automatically activated.

    Clay, 2.5 mm thick HDPE liner, liner protected with fine sand, geotextile and drainage gravel (bottom drainage of leachate).

    Environmental restoration takes place on conclusion of placement, following an initial settlement phase and envisages seeding and the planting of trees and shrubs through an environmental insertion project. 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.

    The landfill site is delimited by a basic embankment to ensure hydraulic safety against all possible flood events that could affect the area.
    The following activities are carried out so as to ensure maximum environmental protection and compliance with all environmental prescriptions:

    • monitoring and control of surface water and waste water;
    • monitoring and control of groundwater and drainage water;
    • monitoring and control of leachates;
    • monitoring and control of atmospheric emissions and air quality;
    • monitoring and control of usage - water withdrawals;
    • monitoring and control of usage - raw materials;
    • monitoring and control of usage - fuel;
    • monitoring and control of energy - production and usage;
    • control of dedicated environmental protection plants and equipment.
