Engineers cut out an unnecessary step
It’s been argued that the process of making biofuels uses more energy than it produces. But 91¿´Æ¬Íøies Neil Stacey (BSc Eng 2009, PhD 2016), Aristoklis Hadjitheodorou (BSc Eng 2009) and Prof David Glasser have been in the news (Creamer Media’s Engineering News) for their on energy-efficient production of bioethanol-enriched petrol. Their , published in Energy & Fuels, suggests that existing bioethanol plants can be retrofitted to use the new process.
