Aston University scientists tackle challenges of converting rice straw into biofuels

In the UK, Aston University scientists are to tackle some of the challenges of how to make inedible rice straw into the next generation of biofuels. In recent years, biofuels and biobased chemicals have been blended with petrol to create a more sustainable alternative. The Aston University researchers are to examine issues that currently hinder the conversion of rice straw into an alternative fuel.
Currently the production of biofuels mainly relies on sugar crops such as sugarcane and sugar beet, which raises major concern about the competition between growing crops for food or fuel. However plant dry matter such as rice straw is seen as a better alternative to current crops because it doesn’t affect food security. Rice straw is often treated as an agricultural waste by-product and is removed by burning in the field.

Their two-year project, An integrated approach to ethanol production from rice straw via microwave-assisted deep eutectic solvent pretreatment and sequential cultivation using Candida tropicalis and Saccharomyces cerevisiae, will explore cleaner and cost effective methods to extract rice straw’s energy-containing molecules.
