GreenGas AD Plant is a state of the art farm based Anaerobic Digestion plant located outside Shanagolden in County Limerick. The biogas plant processes manure and slurry from McDonnell Farms poultry and dairy farm as well as other imported feedstock. We convert the energy contained in these materials into a usable form of energy, such as electricity. This is done in a very safe and environmentally conscious way.

The biogas produced in the anaerobic digestion process is used as fuel in a high efficient Combined Heat and Power Engine (CHP) which produces electricity and heat. We use some of the electricity produced for onsite use with the majority exported to the national grid and the heat is used in both onsite and in the nearby poultry enterprise. The nutrient rich digestate is used on local farm land as a high quality eco fertiliser.
