First Minister Michelle O'Neill and deputy First Minister Emma Little-Pengelly have welcomed a major £9 million investment by O&S Doors to install a cutting-edge biomass-fuelled Combined Heat and Power (CHP) system.

The project is supported by a £2.4 million grant from the Shared Island Sustainability Capital Grant Scheme.

The Dungannon-based company is the first business on the island of Ireland to adopt this specific technology. The system is designed to convert MDF dust—a byproduct that was previously sent to landfill or exported to Europe for processing—into 6.3 million units of energy. This renewable energy will be used to power the site's heating and manufacturing operations.

The initiative will see more than 10,000 tonnes of MDF dust burnt annually to generate 1 MW of electricity, resulting in a carbon saving of 1,500 tonnes per year.

First Minister Michelle O'Neill, speaking during a visit to the facility, stated: "This is a hugely innovative investment by O&S Doors and a real commitment to sustainable manufacturing. Turning MDF dust into clean energy is good for the environment and makes economic sense."

She added: "I am delighted to see a local company leading the way with technology of this scale and ambition, helping to position the North as a place where green innovation and advanced manufacturing go hand in hand." Deputy First Minister Emma Little-Pengelly commented: "As a locally based company, O&S Doors is a success story for our manufacturing sector, and this latest investment will ensure the company continues to grow and thrive. Investing in high-efficiency technology and greener ways of working is essential if we are to harness our economic potential, drive productivity and boost our growing reputation on the world's economic stage while creating jobs and supporting long-term growth."

Economy Minister Caoimhe Archibald highlighted the importance of regional balance, noting that the project demonstrates how industries across the region can lead in Net Zero commitments.

The CEO of O&S Doors, John Toomey, explained that the investment is a "central pillar" of the company's goal to achieve net-zero emissions by 2028. He noted: "This investment also aligns with our growth strategy to expand our Dungannon site in the future by providing us with reliable, cost-effective renewable energy. We are also hopeful that the new CHP system will increase our efficiency and productivity by removing waste handling constraints in our manufacturing process."

O&S Doors is currently the largest manufacturer of wooden doors and panels in the UK and Ireland, serving major clients including B&Q, Magnet, and over 300 independent retailers.

The grant is part of the Shared Island Enterprise Scheme, a collaborative effort between InterTradeIreland, Invest Northern Ireland, and Enterprise Ireland. Invest NI's Chief Development Officer, Alison Currie, confirmed that details regarding two other projects funded by the scheme will be released later this year.
