Work Commences on Harper Biodigester

UK - Work starts this week on a 33m anaerobic digester at Harper Adams University College's Shropshire campus.

It is expected to be generating heat and power from farm and food waste by the end of March 2011 and should offset campus carbon emissions by more than three times.

The plant has been in planning for two-and-a-half-years. It has been designed by BiogenGreenfinch, working with energy company Eon and local contractor Adonis Construction.

Harper Adams is one of three higher education institutions in England to have won a share of £10million for "transformational" projects.

"Food and farm waste can be digested in the anaerobic digester unit and recycled into three useful by-products instead of being left to degrade in landfill or elsewhere, leaking methane into the atmosphere," said Harper Adams principal David Llewellyn.

"Biogas will fuel a unit producing both heat and power meaning we will be sheltered from fluctuating energy prices for at least the next ten years and will make a significant contribution to reducing greenhouse gas emissions for our campus."

Other products of the process are liquid fertiliser and compost, which can be used for the college farm and grounds, reducing reliance on manufactured fertilisers. This will, in effect, bring the Harper Adams food chain full circle.
