Co Tyrone firm Linden Foods has invested over £1m in the business following a deal aimed at reducing its carbon footprint.
The Dungannon company invested the money in improving its environmental performance, after entering into a 'prosperity agreement' with the Department of Environment (DoE).
Prosperity agreements are voluntary agreements, through which the Northern Ireland Environment Agency (NIEA) and an organisation can explore opportunities for reducing environmental impact.
Environment Minister Mark H Durkan said: "The progress made by Linden Foods is most impressive.
"Its carbon reduction initiatives include a new refrigeration and heat recovery system, the only facility of its kind on the island of Ireland.
"This system is already delivering a reduction in CO2 emissions by some 75%. This alone will deliver an overall 24% reduction for operations here."
