Green Energy & Sustainability
Our commitment for a greener future
Anaerobic Digestion
In 2009 we built our first anaerobic digester enabling us to produce our own biofuel. Several lorryloads of organic and vegetable waste arrive on site daily to feed our digester. Millions of bugs then get to work, breaking down the waste and releasing methane gas in the process. The gas is burnt to power the engines, which in turn generate enough electricity for us to export approximately 1.3MWh to the National Grid after meeting the power demands of the business.
The benefits for us are numerous
We are producing our own bio fuel, methane gas, from 2 anaerobic digesters and this gas is used to run our engines rather than a fossil fuel. As well as providing us with heat, electricity and CO2, we are able to generate enough electricity to power around 1,000 homes. By using a green fuel source, it enables us to claim Renewable Obligation Certificates.
The achievements
What could be better than using waste to give us warmth, electricity and CO2 to produce a new and revolutionary eco tomato. The CO2 produced by the engine is cleaned and then pumped into the greenhouses to support plant growth. For us at Guy and Wright it’s about sustainability, as well as diversification. We are committed to producing tomatoes with the lowest carbon footprint in the UK.
Helping Local Farmers
Our energy plan ensures very little waste. The liquid which is left behind in our anaerobic digester is high in nutrients and is pumped into our storage lagoon. Twice a year the lagoon is emptied using an umbilical hose which transports the liquid up to 6 kilometres and it is applied to arable crops as fertilizer, rich in nutrients. There is a strict system in place to test all the soils on which the fertilizer is applied. This is proving to be a valuable resource for our farming neighbours and shows that even the waste from the waste is actually an eco-friendly asset.
