Energy from chocolate waste!
Like animal fat and grease, food waste can also be turned into fuel.
A few years ago, researchers at the University of Warwick launched a Formula 3 car that ran on chocolate.
Scientists have previously produced hydrogen by feeding sugar-munching bacteria nougat and caramel waste provided by a Cadbury’s factory. Fed into a fuel cell, the hydrogen reacted with oxygen and generated clean electricity, which was used to power a fan.
Lynne Macaskie, a bioscientist from the University of Birmingham, led the research and observed that the technology could be scaled up for industrial electricity and waste treatment purposes.
This would save manufacturers costs by reducing the amount of waste that needs processing.
