Biodiesel at Tesco

Tesco will become the second supermarket to see biodiesel - a blend of low sulphur diesel and rapeseed oil - on its forecourts. The new fuel, first trailed at Sainsburys at its Greenwich store in January will go on sale at Tesco's Hatfield store by the end of the month.

The move follows Tesco's £1.9m purchase of a 25% stake in Greenery Fuels, which is supplying both companies.

The fuel, which Greenergy claims reduces greenhouses emissions by 5% and harmful particulate gas emissions by 20%, does not require drivers to make any engine modifications.

Separately, Asda has been piloting a project recycling its own waste fat for use in its transport fleet in a bid to develop a closed loop recycling system, said a spokeswoman. "We are approaching this in a different way to the others as we want to buy back our own waste."

However, Morrisons, which started testing a form of biodiesel in its fleet last year, said it would not be pursuing trials as the fuel was not of sufficient quality.
