To date, 28 local authorities have formally adopted waste management plans under the Waste Management Act, 1996. They are Carlow, Cavan, Clare, Cork, Donegal, Dun Laoghaire-Rathdown, Fingal, Kerry, Kildare, Kilkenny, Leitrim, Limerick, Mayo, Meath, Monaghan, Offaly, Roscommon, Sligo, South Dublin, Tipperary (North Riding), Tipperary (South Riding), Westmeath, Wexford, Wicklow and Waterford County Councils; and Dublin, Limerick and Waterford Corporations. Meaningful and comprehensive planning are a key prerequisite to improved waste management performance and, accordingly, considerable effort has been devoted at national, regional and local level to delivering effective results in this regard.
