Landfill Operations

The Arthurstown landfill is operated and managed by South Dublin County Council. Following an EU procurement procedure process, a contract was agreed between South Dublin County Council and VEOLIA Ireland limited for the waste baling and disposal activities, operating through the Ballymount waste baling and transfer facility. VEOLIA Ireland was purchased by GREENSTAR Ltd during 2010.

Bales-stacked

Placement of baled waste at Arthurstown

A Joint Venture agreement covers the operation of the Council’s Municipal Waste Baling Centre and Civic Amenity Facility, located at Ballymount Avenue, Walkinstown, Dublin 12, and the transfer of baled waste from there to the landfill at Arthurstown. The contract also encompasses the placement/covering of baled waste at Arthurstown. Since January 2001, municipal waste has also been delivered for Thornton’s Baling Centre located on Killeen Road, Dublin 10.

The Facility Management team, who are employees of South Dublin County Council, are responsible for the day-to-day control of the landfilling and waste license compliance.

Traffic

Waste delivery vehicles are controlled at the site entrance and do not access the active landfill area directly. The use of a specified delivery and return route from the site prevents heavy vehicles from using the nearby village of Kill. The marshalling yard serves as the interface between off-site and on-site waste handling traffic. Fuelling services are provided on site for off-road vehicles.

Waste Covering

Waste is covered here hourly and at the close of operations each day so that none is visible. When final design waste levels are reached in a particular area, a temporary capping layer of clay is laid down to act as cover until the final cap is constructed. Cover methods used are as follows:-

  • Vertical Face
    2 layers of plastic sheeting (for daily cover) or sloped clay covers (for more than 3 days)
  • Horizontal Face
    a minimum of 200 mm and up to 600 mm of clay or sand in the active cell area
  • Temporary Capping
    a minimum of 700 mm and up to 1500 mm of clay placed on top of the final waste level to allow settlement before construction of the final capping.

Landfill Operations

The waste arrives at Arthurstown in fully enclosed containers from the pre approved Baling Stations. The load is then weighed in on the fully automated weighbridges before entering the marshalling yard area. The full container is deposited on the hydraulic stillage units and the truck then picks up an empty container and returns to the weighbridge before exiting the facility and returning to the Baling station.

The full container is then picked up by the RTV (Specially designed VOLVO 6 WD Vehicle) and brought to the working face.
On arrival at the working face the front and rear doors are opened and the hydraulic ram is engaged. It pushes the bales out from the container 2 at a time and presents the first 2 bales on the rear platform. The Grab vehicle then picks the 2 bales (4 tonnes) and stacks them at the working face.

Municipal waste landfill activities require the implementation of measures for the control of: Litter, odour, birds/insects/vermin.

Litter

The consolidation of waste and strapping it into bales means that this form of land filling dramatically reduces the problem of wind blown litter. Litter nets are used to ensure that no waste leaves the working area. Waste is delivered in fully enclosed containers that are opened only at the working face. Regular litter patrols are carried out to maintain a litter-free site.

Odour

Odour can arise from the waste itself or from constituents of landfill gas. To minimise waste odours, the waste is covered (as described previously) and odour control products are sprayed on the working area. Landfill gas-related odours are controlled by collection and flaring of gas. Additional spraying of odour control products is carried out on the landfill area if residual odours are detected. (See section on Odour Control at Arthurstown)

Birds, Insects, Vermin

A specialised contractor is engaged on a full-time basis to implement a dawn-to-dusk bird control programme and measures for the control of insects and vermin. Birds of prey (Peregrine Falcons and Harris Hawks) are the primary deterrent used.
