Fuel made from pasties to run cars
Cornish pasties are to be used to power cars after a green fuel firm announced plans to use them to make biodiesel.
Greenergy is to take pasties, pies, crisps and other food waste that would otherwise have gone to landfill and extract the oil they contain. It will then be blended with diesel and sold at petrol stations across Britain.
The company, which produces 10 billion litres of biodiesel and diesel annually, is investing £50 million in its production facility in Immingham, Lincolnshire, to process used cooking oils which can make up to 30% of some processed foods.
Andrew Owens, Greenergy's chief executive, said: "We've always tried to find ways of reducing the environmental impact of our fuel and as oil prices continue to rise, it's obviously important to develop alternative sources of fuel.
"The quantities of biodiesel that we're currently producing from solid food waste are small, but we're expecting to scale up so that this soon becomes a significant proportion of our biodiesel.
"It's great to be taking these products, which would otherwise have gone to landfill or compost, and turning them into a new source of fuel."
Greenergy is working with Brocklesby Ltd, which developed a method of extracting oil from food waste. It then purifies the oil further and turns it into biodiesel.
Any food solids that remain are dried and either composted or used to produce energy through anaerobic digestion. But the firm has plans to use the waste to make solid biomass fuel pellets or briquettes, or more fuel for cars in the form of bioethanol.
