Arla Foods started using biogas fuel at its Aylesbury dairy this week in a bid to cut carbon emissions.

The fuel, which is produced by Gasrec, powers 24 trucks, but Arla plans to roll it out to 80 trucks this year as part of its strategy to reduce its environmental impact.

Gasrec CEO Rob Wood said the fuel - a blend of liquefied biomethane and liquid natural gas - would deliver a 20% fuel cost and 20% carbon saving at the dairy.
