Pioneering green fuel company Regenatec has won a major contract to supply its technology to a bus company.

Regenatec, based at Milton Park, near Didcot, is fitting its conversion kits which allow vehicles to run on a mixture of rape seed and soya oil, to 10 buses operated by Bracknell-based Courtney Coaches.

The rest of the 34-strong fleet will be converted within the next year and Regenatec has also lined up a deal with refuse truck manufacturer Dennis Eagle.

Regenatec bosses declined to reveal the value of the Courteny Coaches but claimed its Optare Solo buses will be the greenest fleet in the UK.

Will Smith, business development director of Regenatec, said: "This is our first significant contract and the first time that out technology has been available as an off-the-shelf factory fitted option."

Bill Courtney, managing director of Courtney Coaches, trialled Regenatec's technology in two of his buses based at Milton Park.

He said: "I'm delighted with the vehicle performance. The fact that I can now offer near CO-neutral, low emission vehicles to my customers means I have a contract-winning advantage over competitors.

"The fuel savings alone make converting vehicles a sound business case."

Dennis Eagle has also had several successful trials with key customers and is set to start adapting vehicles next year.

Regenatec founder Mike Lawton added: "These latest developments with two such major companies signal a huge step towards a low-carbon future for the bus and municipal vehicle industry.

"With pure plant oils carbon emissions are reduced by more than 80 per cent."
