In the UK, Argent Fuels has expanded access to its High Blend Biodiesel to supply bus, coach, HGV fleets and rail in the south of the UK. As part of Argent Energy, Argent Fuels produces its own waste-based biodiesel, providing a sustainable alternative to fossil diesel. In 2008, it became the first UK business to supply high-blend biodiesel on a commercial scale. Today, Argent Fuels powers more than 9,000 diesel vehicles nationwide, including those run by leading transport providers such as Metroline and Transdev.
