From Chicken Litter to Clean Energy in Ireland

Irish biogas developers are turning poultry manure into biomethane, easing farm waste pressures while strengthening local energy supply

19 Jan 2026

Ireland’s renewable gas sector is quietly accelerating, and it is doing so in an unlikely place. On farms, where piles of poultry manure have long posed an environmental headache, developers now see a dependable energy resource.

A proposed biogas plant in County Monaghan offers a clear example. Led by Stream BioEnergy Ireland, the project would process nearly 100,000 tonnes of poultry manure and other farm residues each year. The output would be biomethane for the gas grid, along with digestate that can be reused as fertilizer. For a region with intensive farming, that combination promises relief on multiple fronts.

The Monaghan proposal reflects a broader shift in the biogas market. Earlier projects often leaned on food waste from cities and industry. Developers are now prioritizing agricultural byproducts that are produced locally and year round. Poultry manure, while difficult to handle, is abundant and predictable, making it attractive for large scale plants designed around consistent feedstocks.

Policy is pushing the sector in the same direction. Ireland and the European Union are tightening manure management rules to protect waterways and reduce emissions. At the same time, governments want more homegrown biomethane to bolster energy security. Projects that solve waste problems while producing renewable gas fit neatly into both agendas.

Analysts say the appeal is straightforward. Converting a disposal risk into an energy asset stabilizes gas output, supports farmers, and improves nutrient recycling. Across Europe, industry groups are urging closer links between agriculture and renewable energy to unlock these benefits.

Still, challenges remain. Large manure based plants can trigger local concerns over traffic, odor, and land use. Developers must show that modern designs and strict operating standards can limit those impacts. Supporters counter that centralized treatment is safer and cleaner than unmanaged spreading.

For Ireland, the Monaghan project signals a more pragmatic phase of biogas growth. By anchoring new plants in farm waste, developers reduce supply risk and strengthen the case for long term investment. If the model succeeds, its influence may travel well beyond Irish fields.
