The first school in the UK or Ireland to use waste packaging to produce free heating is in Co Tyrone.
Dungannon Integrated College will recycle refuse from Greiner Packaging Ltd in ‘Project SCool’, saving around £40,000 and 200 tonnes of carbon emissions a year, the Department of Education said.
The company has a workforce of more than 3,000 employees at 34 sites.
Education Minister John |O'Dowd said: “With the rising cost of energy, it is imperative that renewable alternatives are sought and fully utilised whenever possible.
“Project SCool is a practical example of innovative thinking and investment that will also lead to shared financial and environmental benefits for both Dungannon Integrated College and Greiner Packaging.”
His department provided £58,000 towards the scheme.
Enterprise Minister Arlene Foster said: “Project SCool is an example of this commitment to innovation. Not only is Greiner meeting its own energy efficiency needs and reducing its carbon footprint, but Dungannon Integrated College is benefiting from a highly efficient heat supply that has reduced the school's overheads.”
