Ireland's agricultural sector produces approximately 40 million tonnes of livestock waste annually, presenting a significant opportunity for renewable energy through small-scale biogas systems. Currently, Ireland has only 31 biogas plants, with just 10 processing animal by-products, compared to about 21,100 facilities in the EU and 427 in the UK.

Financial viability for small-scale anaerobic digestion is challenging, with a 44-kilowatt plant costing around €450,000 but generating only €105,148 in revenue against €115,800 in costs. Without government intervention, achieving payback remains elusive.

Current Irish support primarily targets large-scale biomethane plants, leaving smaller operations disadvantaged. Experts suggest future schemes should consider carbon savings to enhance competitiveness. Widespread adoption of anaerobic digestion could significantly reduce emissions and improve air quality, but effective policy frameworks are needed to support this transition.
