8 November 2007: Green Chocolate

Lovers of chocolate can now help the environment.

English firm Ecotec has taken waste from the chocolate manufacturing process and turned it into an eco-friendly bio-diesel. Bio-diesel can replace conventional fuel in an unmodified diesel engine, thus reducing dependency on fossil fuels.

The chocolate waste used to be put into landfill, making its conversion into a useful fuel a double benefit.

But sadly one of the team confirmed that one hoped-for by-product of the new process hasn't materialised. "I'm afraid the exhaust doesn't smell of chocolate," he said.
