(NaturalNews) Chocolate is not just a pleasurable treat anymore. Researchers in the UK have discovered a way to convert waste produced from chocolate manufacturing into viable eco-fuel. Whether environmentally friendly biodiesel or hydrogen for fuel cells, both can now be produced using chocolate factory refuge. Taken a step further, a semi-biodegradable Formula 3 race car has been designed to run off this unique fuel.
A team of scientists in Britain have harnessed the unlikely fuel source of waste caramel and nougat from chocolate manufacturer Cadbury Schweppes. As part of the experiment, Escherichia coli bacteria were fed the sweet left-overs from the factory. The bacteria then belched out hydrogen gas after a process of sugar fermentation and conversion of formic acid. This surprising source of hydrogen was subsequently used to power a small fan via fuel cell technology. As a highly efficient source of energy, fuel cells have a zero emission rate when used with hydrogen. Professor Lynne Macaskie, who lead the study at the University of Birmingham
"Although only at its initial stages, we've demonstrated a hydrogen-producing, waste-reducing technology that, for example, might be scaled-up in 5-10 years' time for industrial electricity generation and waste treatment processes."
With such an innovative approach to renewable energy, both industry and the environment benefit. The process is not only limited to chocolate waste. The entire food industry could conceivably use their own waste as a clean source of energy for manufacturing, thereby revolutionizing electricity consumption and waste management.
Chocolate-based fuel powers plant fiber car
Partially constructed of plant fibers and powered by biodiesel, an extraordinary race car has been developed at the University of Warwick
in the United Kingdom. A few of the eco-friendly materials that make up the car
include: soybean oil foam and recycled polyester seats; plant-based lubricants; recycled bottles for the side pod; a steering wheel made of cellulosic fibers from carrot juice pulp; molded potato starch and flax fiber front wing and mirrors. The car is fueled by 30 percent biodiesel derived from chocolate
waste. James Meredith, who oversaw the project, remarks, "Anything with a fat in it can be turned into diesel, and that's what we've managed to do." Currently, Formula 3 rules forbid chocolate-based biodiesel fuel
, but the team hopes to overcome this obstacle soon.Sources for this article include:
