Arigna Group is an Irish solid-fuel pioneer that is pivoting from traditional coal-based products to sustainable, low-carbon alternatives. Its flagship offering, Harvest Flame, is a low-carbon fuel designed to replace conventional solid fuels in residential and commercial heating. In parallel, the company is scaling a portfolio of biochar products that improve soil health, sequester carbon and can also be used in construction materials. The firm’s strategy centres on decarbonisation, rural job creation and leveraging its historic manufacturing base in Arigna, Co. Roscommon. The newly announced €800,000 funding will accelerate Harvest Flame’s rollout and expand biochar production capacity. Management emphasises that the capital will safeguard existing jobs while positioning the company for medium-term employment growth. Previous backing from the Western Development Commission in 2019 supported the initial phase of this green transition, and the latest round further solidifies its long-term sustainability roadmap.
