The Anaerobic Digester at Harper Adams

Anaerobic Digester

The University has expanded its commitment to sustainable energy with a £3million-plus renewable power system. Harper Adams was just one of three higher education institutions in England to have won a share of the £10 million set aside for 'transformational' projects under the Higher Education Funding Council for England's Revolving Green Fund. The Anaerobic Digester plant, constructed in 2011, started generating heat and power at the end of April 2011.

Using farm and food waste, it is anticipated to offset campus carbon emissions more than three times over. Renewable electricity is produced from food and farm waste and provides a highly effective waste management system.

The waste is digested in the AD unit and recycled into a liquid fertiliser and compost, which can be used for the University's farm and grounds operations, reducing reliance on manufactured fertilisers.

Key Facts

  • Creates renewable heat and electricity from waste
  • Uses 11,000 tonnes of dairy and pig slurry
  • Uses up to 12,000 tonnes of food waste that would otherwise have gone in to landfill
  • Bacteria break down the organic matter in a tank releasing Biogas
  • Biogas burnt to create heat and electricity
  • Anticipated to save over 13,000 tonnes of CO2 per annum, offsetting campus carbon emissions more than three times over
  • Other by-products of the process are a liquid fertiliser and compost that will be used on the University Farm and grounds
