Symonds Farm Anaerobic Digestion Plant

The Symonds Farm Anaerobic Digestion Plant at Risby, Bury St Edmunds generates 1.4MW of electricity which supplies several local businesses with the surplus going into the national grid. The site is owned 50% by Material Change in a joint venture with Landowner GEO Gittus & Sons.

Construction started in 2011 and was completed in 2012. Infrastructure to allow the drying of wood chip for the adjacent briquetting plant using surplus heat from the engine was installed in 2014.

Crops for the plant are grown locally to the Farm and digestate produced by the plant is spread back to local farm land, given good nutritional enhancement to the soil.

The site continues to expand its’ private wire supply network and will soon be selling 30% of its electricity directly to local businesses. Planning permission for waste inputs which will allow on expansion of the plant (generating the approximate equivalent of 3MW of gas) was granted in 2015.

Site visits are a popular part of science week for local schools with several hundred children visiting and learning about renewable energy first hand.
