Composting/Biogas Facility, Foynes, Limerick

  • Client: Greenport Environmental Limited
  • Value(€ million): 24
  • Value($ million): 33
  • Completion date: 2011
  • PUNCH services: Lead consultant

Due to site constraints at Luddenmore, a 12 acre facility was obtained at Foynes Port. A change of use planning was sought for the existing 4500m2 building to allow a pilot composting process to be established. PUNCH were the lead design consultants in the preparation of the planning application and design. During the initial planning process, the proposals for the overall biogas/composting facility was developed by PUNCH. The facility is a 10,600m2 building which includes 24 tunnels for the aerobic and anaerobic treatment of organic waste which includes extensive leachate recirculation systems and biogas/leachate storage.

PUNCH have been employed as Civil Engineers by Mr. Binman Ltd since 1998 and have been the lead consultant on the additions to the main waste processing facility at Luddenmore, Kilmallock, Co. Limerick which currently caters for 105,000 tonnes of waste per annum and 60,000 customers in the Mid West Region.  Mr. Binman Ltd. are committed to MBT (Mechanical & Biological Treatment) as an alternative to energy recovery, by thermal treatment, in the waste hierarchy. The main plant in Luddenmore contains extensive mechanical separation systems for both the source separated and residual waste streams. These include the separation of the organic fraction of residual waste for further biological treatment to render the material inert (stabilised biowaste).

The plant is designed to provide an end product which complies with Department of Agriculture requirements for animal by-products and BAT guidance for emissions. The total tonnage of organic waste to be treated in the facility is 50,000 tonnes per annum. The facility will be the first of its kind in the country and starts to address the objective of the current Waste Management Plan for the region of biological treatment of 60,000 tonnes per annum. The biogas by-product of the process will be converted via CHP unit to power the facility and provide heat to the tunnels with residual energy being supplied to the National Grid.
