Walkers crisps power AD plant

Potato waste from the Walkers crisp factory, in Peterlee, Durham will be used to produce energy for the National Grid.

Farmer Philip Johnson has asked Durham County Council for permission to produce enough electricity to power 1,200 homes.

An anaerobic digester will be used to take potato waste from the crisp factory and turn it into gas.  Daily throughput would involve 19 tonnes of agricultural crops, 5.5 tonnes of cattle manure and 2.7 tonnes of potato waste. The process would result in the production of 8,000 tonnes of organic fertiliser and a constant supply of 500Kw of electricity for the National Grid.

The waste from the farm in Peterlee comes from Johnsons 800 acres in County Durham and North Yorkshire.
