The world of the 21st century faces some incredibly daunting challenges that, unless dealt with soon, may eventually reach the point of no return. Overpopulation, water shortages, and climate change is just some of the long list of problems facing the world. Researchers in the UK may have come up with a clever solution to dealing with food waste and creating affordable hydrogen fuel.
Scientists at the University of Birmingham are proposing a system that uses food waste, like the leftovers from chocolate processing, that would turn the waste into biohydrogen. This sustainable source of hydrogen fuel could even be applied towards ethanol production, resulting in a sort of two-for-one biofuel, and could be applied to waste food found in the trash, as well as the leftovers from processing.
Food waste is already being used in a variety of biofuel processing techniques, ethanol and biodiesel among them. One problem facing hydrogen infrastructure is sourcing enough of the clean-burning gas to support our large transportation needs. But there will always be food waste to go around, and if we can get a variety of biofuels, hydrogen among them, from collected food waste, it’s like killing two birds with one very clean stone.
