Food Fights: The Biggest Culinary Scandals Of 2011
Sometimes science is entertaining enough to make one stop and ponder the endless possibilities of being truly resourceful. A group of researchers at University of Birmingham, UK, have discovered a way to create power by using the waste generated by a chocolate factory. Microbiologist Lynne Mackaskie and her colleagues at the university fed Escherichia coli bacteria a diluted chocolate waste. Upon consuming the sugary mixture, the bacteria produced hydrogen, which is produced with the enzyme hydrogenase, and organic acids. The hydrogen was then used to power a fuel cell, which generated enough electricity to drive a small fan. If not used, the candy waste ends up in a land fill after the production line. The idea of recycling in such a manner is akin to the idea behind bio-diesel fuel. This could be an exciting alternative energy source to consider as we face the facts of our quickly disappearing fossil fuels.

I don't know about throwing chocolate production waste in the landfill - I distinctly remember a whole semi-trailer load (approx 40,000 pounds!) that my husband and I delivered to a plant where it would be processed with chicken feed and sold to poultry feed outlets. (It was "Cadbury's" - since we're both chocoholics, it was torture because the load had a seal on it but you could still smell it when you walked behind the trailer.)
Still, since I love chicken anyway, I think of that often when I bite into a grilled chicken breast sandwich...
