Turning food waste into hydrogen

Scientists from Purdue University in the US have developed a new way of producing hydrogen from food waste.

The new method developed by scientists uses yeast to break down the food waste and turn it into clean hydrogen for further use with minimal pre-processing steps in approximately 18-24 hours.

“We wanted to create a simple way to turn all that food waste into a source of clean energy,” said Robert Kramer, NiSource Charitable Foundation Professor of Energy and the Environment and Professor of Physics at Purdue University Northwest.

“Our system basically allows a user to take food waste, grind it, place it in a reactor and use our process to create hydrogen in about 18-24 hours. That’s much faster than the days it takes with other methods.”
