Have a nice sip of single-malt whiskey and know you are doing your part to help with climate change. Scientific researchers raised their glasses to the successful launch of a car that runs on biofuel made from the remnants of making whiskey!
After whiskey is made there are kernels of the barley left over and they continue to ferment and continues to make alcohol, which can be used as a biofuel. It would be very nasty to try to drink this alcohol, but it does burn efficiently as a fuel, and it burns very cleanly with low airborne pollutants.
Paste says that the performance of a car running on “whiskey” fuel is as good, or better, as running on gasoline or diesel. The students and researchers at Edinburgh Napier University in Scotland found the process to make the discarded barley into a fuel source, and then they spun off the technological solution to a company called Celtic Renewables Ltd. The alcohol biofuel comes from a natural process with the barley that was normally discarded as waste. In fact, if the distillers do not send the waste to a safe facility, it can become a fire hazard because the natural distillation continues far after the effective time needed for making scotch whiskey.

The process of creating this biofuel is really easy. They simply collect the waste in vats and extract the alcohol that is naturally created. Nothing could be simpler than that. Any fermentation process has this dynamic, so this technology can be exported from Scotland to all parts of the world. The steps are so easy; A) get the scotch, vodka, or wine or whatever we like to drink; B) let the fermentation process continue, and: C) collect the alcohol produced thereafter to use as biofuel.
Though the steps are simple, there is a major issue when bringing this biofuel to the mass market. Professor Martin Tangney, the founder and President of Celtic Renewables says this happens naturally, and if the alcohol is not collected as a biofuel it is hazardous. This makes a potential problem into a saleable solution
This technology has major implications for positive improvements in Scotland, Ireland, the UK, the USA, and Japan where whiskey making is really popular.
