The hunt for a commercially viable biobutanol could finally be over thanks to an inspired, if ironic, bit of recycling by scientists working at Edinburgh Napier University in Scotland.
They've taken the two main waste products from the Scotch whisky production cycle and brought them together in a process which outputs biobutanol, long heralded as a next generation biofuel because it produces up to 30% more power than ethanol and can be used in existing combustion engine cars without modification.
The process has now been patented by the University which has also set up a limited company to leverage the commercial possibilities of the invention.
Professor Martin Tangney, Director of the Biofuel Research Centre at Edinburgh Napier University, believes the biofuel could be sold at garages alongside normal gas. He said, “I would expect to see this as a fuel in forecourts in years rather than decades”.
