Our fuel gives a saving of greenhouse gas emissions over fossil diesel of 90% and is the most sustainable and environmentally friendly diesel for road vehicles available. Raw materials include tallow (waste animal fat), food waste, trap grease, brown grease and the fats, oils and greases (FOG) recoverable from sewage systems and water treatment works. our biodiesel plant have specialised pretreatment plant alongside to allow the use of highly degraded and off-spec raw materials that other plants are unable to cope with (e.g. FFA levels up to 100%).
