Herriard Bio Power, located in Basingstoke, converts food waste and crops into biogas which exports over 10 million kWh of clean, green energy every year through a 1.2MW CHP engine – enough to power 2,200 homes.

The plant is fed with approx. 5,000 tonnes of maize / rye crops from the surrounding estate. The main amount of biogas however comes from 20,000 tonnes of food waste. The food waste is sourced from commercial and domestic waste streams.

The plant produces around 20,000 tonnes of environmentally friendly, premium quality, nutrient–rich organic fertiliser each year. The digestate bio-fertiliser is rich in Nitrogen (N), Phosphate (P) and Potassium (K). The digestate is pumped straight from the AD plant, via a pasteurisation process and into our on-site lagoon and then onto surrounding farmland, via underground piping network. The use of carbon-intensive synthetic fertiliser is greatly reduced through this process.
