In the heart of Co. Waterford, E. Flahavan & Sons Ltd. has been milling oats since 1785. While the company is best known for its wholesome porridge oats, its deeper legacy lies in its commitment to sustainability and innovation, and its role in Ireland’s evolving bioeconomy. Flahavan’s exemplifies how traditional food enterprises can lead the way in climate-smart agriculture and circular resource use.
We source most of our conventional oats from a network of growers within a 60-mile radius of the mill, reducing transport emissions while supporting local farming communities. Our supply of Irish-grown organic oats has also expanded significantly in recent years, driven both by rising consumer demand and by the company’s advocacy for national organic farming schemes. But beyond the grain itself, Flahavan’s is increasingly turning its attention to what was once considered a low-value by-product: the oat hull.
New opportunities
Oat hulls, the fibrous outer layer removed during milling, have traditionally been used for animal bedding or biomass fuel. However, recent research by Teagasc has highlighted new opportunities. Scientists are developing methods to extract valuable protein and dietary fibre from oat hulls, transforming them into functional ingredients for food, feed, and bio-based applications. This work reflects the principles of the bioeconomy: maximising the value of biological resources while minimising waste.
Collaboration between Teagasc and industry leaders like Flahavan’s opens the door to new product streams and revenue models. By valorising oat hulls, we can further reduce our environmental footprint while contributing to Ireland’s circular bioeconomy. Potential applications range from high-fibre food additives to biodegradable packaging materials, showcasing how innovation can unlock hidden value in agricultural by-products.
Embedding sustainability
Flahavan’s sustainability journey is deeply embedded in its operational ethos. From our early use of a waterwheel to power the mill, to modern investments in energy efficiency and packaging innovation, our company has consistently demonstrated leadership in environmental stewardship.
Today, Flahavan’s generates roughly 70% of its total energy needs from renewable sources, offsetting around 2,000 tonnes of CO₂ emissions annually and reducing reliance on almost half a million litres of diesel. Our transition to a low-carbon food processing facility began with on-site hydro generation, later strengthened by a 500kW wind turbine installed in 2015. Additional contributions come from a water turbine, rooftop solar PV, and the use of oat husks in a biomass boiler.
As Ireland works to scale its bioeconomy, Flahavan’s stands as a compelling case study of how legacy businesses can evolve through science, collaboration, and purpose-driven strategy. The integration of Teagasc research into its operations not only enhances resource efficiency but also positions Flahavan’s as a pioneer in bio-based innovation. This case underscores the value of linking applied research with industry practice to deliver tangible bioeconomy outcomes.
