Fresh look at biofuels
Engineers cut out an unnecessary step
It’s been argued that the process of making biofuels uses more energy than it produces. But Witsies 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 work on energy-efficient production of bioethanol-enriched petrol. Their paper, published in Energy & Fuels, suggests that existing bioethanol plants can be retrofitted to use the new process.
