Two British adventurers drove to Timbuktu and back in a truck fuelled by chocolate.

Andy Pag, 34, and John Grimshaw, 39, made the 2,600-mile trip in salvaged Ford Iveco Cargo lorry and Land Cruisers, using biodiesel made from waste chocolate.

They set off from John?s home at Poole, Dorset, on November 26 and arrived in Mali, West Africa on Boxing Day, reports The Sun.

They overcame sand storms and corrupt customs officials, and drove through a town where days later al-Qaeda terrorists shot dead a French family, to deliver a biodiesel processing unit and the vans to a charity.

Andy said: "We wanted to do a trip that wouldn't have a detrimental effect on the environment."

The pair, who reckon they saved 15 tonnes of carbon emissions, now plan to fly to China in a plane powered by rubbish.
