chocolate power

If you can't eat it... burn it. Two British environmentalists are on their way from Britain to Timbuktu in a lorry running on biofuel made from waste chocolate by British firm Ecotec. And when their load of 2,000 litres of fuel runs out, they can just crank up a small processing unit they are carrying with them to convert waste oil products into fuel, which they will donate to an African charity (Mali-Folkecenter), along with the lorry, at the end of the trip. Sweet.

The two claim their biotruck will be making the first-ever carbon negative expedition across the Sahara Desert through a combination of using biofuel and offsetting emissions with the portable processing unit:

"When measuring the carbon footprint of the expedition we will factor in the offsetting effect of the carbon saved by the fuel that is produced over the next 12 months following the expedition," say Pag and Grimshaw, who expect the project to save 15 metric tons of carbon emissions in the first year alone.
