Leading the way in Anaerobic Digestion

Andigestion Ltd is part of the Summerleaze Group, a leading investor and innovator in the renewable energy sector. Andigestion was established in 2004 to develop and commercialize anaerobic digestion (AD) as a viable waste-treatment technology. As of 2008, Andigestion's plants produce 70% of the electricity from AD of agricultural and commercial wastes in the UK.

Summerleaze is strongly committed to anaerobic digestion as the only system for stabilising and reducing organic matter and diverting waste from landfill that:

• is sustainable
• recovers energy
• is a completely closed system with no emissions to air or land
• returns the organic material to the soil
• facilitates the recovery of heavy metals.

Andigestion currently has two operating anaerobic digesters in the UK, at Holsworthy in Devon and Waterbeach near Cambridge. Further projects are under development.
