Whiskey Waste to Green Fuel: Indian-Led Team Turns Draff into Sustainable Green Fuel

A team of scientists, including an Indian-origin researcher, at Heriot-Watt University in Edinburgh has achieved a groundbreaking feat: producing "green petrol" from whiskey waste.


This eco-friendly and sustainable fuel, more accurately known as green hydrogen, holds immense potential for reducing our reliance on fossil fuels and combating climate change.

  • Whiskey Wastewater to Green Hydrogen: The team used a newly developed nanoscale material called nickel selenide to efficiently convert wastewater from whiskey production into green hydrogen. This process replaces fresh water, a valuable resource, and utilizes waste material, making it doubly sustainable.

  • Green Hydrogen – Not Quite Petrol: While referred to as "green petrol" for its potential to power vehicles, green hydrogen is a different fuel altogether. It burns cleanly, producing only water vapor, unlike gasoline which releases harmful greenhouse gases.

  • Efficiency and Scalability: The nickel selenide catalyst proved highly effective, generating similar or even slightly higher amounts of green hydrogen compared to traditional methods using fresh water. This opens doors for scaling up the production of this eco-friendly fuel.

Green hydrogen offers a clean alternative to fossil fuels, contributing significantly to reducing carbon emissions and mitigating climate change. Transforming whiskey waste into a valuable resource sets a precedent for sustainable waste management in various industries.
