A TD has drafted a new bill which would allow for the development for a national strategy for anaerobic digestion (AD).
The Anaerobic Digestion (National Strategy) Bill 2022 will provide a mechanism for the Minister for the Environment, Climate and Communications Eamon Ryan to create a streamlined approach to the renewable technology.
AD is a process of recycling organic waste matter into a biogas, which can then be used for energy production and as an organic fertiliser, thus reducing emissions and generating low-carbon renewable energy.
Christopher O’Sullivan, the TD who drafted the bill, explained that the current obstacles to establishing and running such facilities have prevented the expansion of this low-carbon technology in Ireland.
“By positively contributing to the decarbonisation of Irish agriculture and the generation of renewable energy by the use of anaerobic digestion, Irish farmers will be enabled to play a key role in slowing down the pace of climate change,” the Cork South West deputy stated.
The Fianna Fáil representative, who is also vice-chair of the Committee on Climate Action, outlined that it would not just be the farming sector that would benefit from and contribute to these facilities.
“Distilleries are growing in number throughout the country, and they’ve had challenges with disposing of the grain used in the distilling process. Used grain can be fed into anaerobic digesters, therefore extending the life and use of the grain and fulfilling some circular economy goals,” Deputy O’Sullivan said.
“An existing medium-scale anaerobic digester in Timoleague in west Cork, produces enough electricity to power 1,000 homes.
“It’s estimated that over a 10-year period it will have stopped an estimated one million tonnes of carbon from escaping into the atmosphere.
“A national strategy will encourage an expansion of this technology across Ireland, and in doing so provide a secure source of renewable energy.
“It’s estimated Germany has 10,000 ADs. In the Republic of Ireland there are 13,” the TD said.
“The strategy could also include micro-scale anaerobic digesters which could allow the hospitality sector, and even households, use food waste to create their own energy to be used in cooking for example, and using the liquid bio-fertiliser for growing more food locally,” O’Sullivan concluded.
