A joint project between Australia’s most famous lager brewer, Foster’s, and the University of Queensland to turn beer wastewater into electricity has won $140,000 from the Queensland Government’s Sustainable Energy Innovation Fund. The technology works using a microbial fuel cell, which feeds continuously on the churning organics in the brewery wastewater, turning it into watts.

The team from UQ’s Advanced Wastewater Management Centre (AWMC) posed for photos at Foster’s Yatala brewery during the presentation of the funding by Minister for Environment Lindy Nelson-Carr on May 2.

AWMC postdoctoral research fellow Dr. Korneel Rabaey said the process also produces clean water and renewable (non-polluting) carbon dioxide, particularly important during the current drought, and a smart use of resources.

“Energy and water supply are among the biggest challenges we will face in the coming decades,” he said.

AWMC Director Professor Jurg Keller said the focus in wastewater management had shifted away from simply treating waste to recovering valuable resources such as water, energy and nutrients.

“Technology that can do this should be supported, therefore the decision by the Queensland Government to support this project is a very important signal, both to universities and industry,” he said.

The team’s work is in collaboration with the University of Ghent, Belgium, and is backed by a $1.3 million Australian Research Council Discovery grant in addition to on site and financial support from Foster’s, who have been recognised for their innovative water reduction and recycling programs.

A patent is pending for the technology — believed to be a world first — which is designed for small to medium operations and could be used across a number of food, beverage and manufacturing industries.

Professor Keller said the team are achieving good progress with a 10-litre prototype, with plans to have a pilot-scale model up and running to coincide with an international bio-energy conference hosted by the University in September.
