Don't throw those old shopping bags out - they could one day be used to power your car.
Scientists
have developed a way to convert plastic shopping bags into diesel,
natural gas and other useful petrol-based products.
The
process of converting the bags into fuel produces significantly more
energy than it requires and leads to transport fuels, including diesel,
that can be mixed with diesel.

Plastic fantastic? Carrier bags could provide a
new source of fuel after scientists manage to convert the material into
petrol, natural gas, oil and wax
Other products, such as
natural gas, solvents, gasoline, waxes and lubricating oils such as
engine oil and hydraulic oil also can be obtained from shopping bags.
Study
author Dr Brajendra Sharma, of the University of Illinois, said: 'You
can get only 50 to 55 percent fuel from the distillation of petroleum
crude oil.
'But since
this plastic is made from petroleum in the first place, we can recover
almost 80 percent fuel from it through distillation.'
Hundreds of billions of plastic
shopping bags are thrown away every year round the world, with some
estimates showing that just one in eight are recycled.
The rest end up in landfill sites, or as litter or in the sea.

Researchers were able to blend up to 30% of their plastic-derived diesel into regular diesel
Plastic bags make up a large portion of the floating rubbish in oceans that kill wildlife and litter beaches.
The carriers have been detected as far north and south as the poles, said the researchers.
Previous
studies have found a way to convert plastic bags into crude oil, but
this is the first to prove they can be made into diesel.
Dr
Sharma's team took the research further by turning crude oil into
different petroleum products that can be used for a multitude of
purposes.
The researchers
were able to blend up to 30 per cent of their plastic-derived diesel
into regular diesel, 'and found no compatibility problems with
biodiesel,' Sharma said.
'It's
perfect,' he said. 'We can just use it as a drop-in fuel in the
ultra-low-sulphur diesel without the need for any changes.'
The findings are published in the journal Fuel Processing Technology.
