Two British adventurers are setting off on a journey across Europe to west Africa in a lorry powered by chocolate.

Andy Pag, of London, and his co-driver John Grimshaw, of Poole in Dorset, were leaving Mr Grimshaw's home town on a cross channel ferry on Friday.

They are travelling in a Ford Iveco Cargo lorry powered by fuel that began life as chocolate, in a bid to raise awareness of green fuels.

The 4,500 mile (7250km) trip across the Sahara should take about three weeks.

The pair will take a small processing unit with them to convert waste oil products into fuel, which they will then donate to an African charity, along with the lorry.

They are taking 2,000 litres (454 gallons) of bio-diesel made from 4,000kg (8,818lb) of chocolate misshapes, the equivalent of 80,000 chocolate bars, to fuel their adventure.

"If we can make it [to Timbuktu] with bio-fuel there's no reason why motorists can't use it on the school run or on their commute to work"
Andy Pag
