The fuel is produced from waste fats and oils.
Mitchell & Webber, a south west oil supplier, is the first distributor to deliver the new, low carbon heating fuel for UK trials, which could revolutionise both the domestic heating market and agricultural sector.
Robert Weedon, managing director, said: “We’re so excited that Cornwall is leading the way in these national trials! This is a huge and much-needed step in the right direction for lowering carbon emissions across the country.”
The fossil-free renewable fuel, called Hydrogenated Vegetable Oil (HVO), is produced from certified waste fats and oils. Unlike previous biofuels, HVO is manufactured by a synthesised process with hydrogen to create a greener, renewable fuel.
