Coal power significantly contributes to carbon emissions in Australia. Your typical coal power plant releases by-products such as fly ash, carbon dioxide gas and wastewater into the environment. But what if we found ways to use this waste?

鈥淲hen we design and produce something 鈥� anything 鈥� we need to consider its lifecycle impacts, its ultimate fate and its reusability,鈥� says Associate Professor Ali Abbas from the University of Sydney鈥檚 School of Chemical and Biomolecular Engineering.

Associate Professor Abbas is referring to a shift from a linear economy to a circular one where the latter finds ways to reuse organic, obsolete products or industrial waste, rather than dispose of them. 鈥淭his is the philosophy of our work,鈥� says Associate Professor Abbas, who has recently received a SOAR Fellowship to support his innovative research in transforming waste to products.

Associate Professor Abbas鈥檚 research explores a transformative approach to power generation in Australia. He suggests we could be using industrial waste to create useful materials for other industrial plants.

For example, fly ash and carbon dioxide gas from coal power plants could be collected to be transformed into an environmentally-friendly cement blend [1], thereby trapping carbon emissions while offsetting the energy used to produce cement from other materials.

Associate Professor Abbas has been working with to make his 鈥榞reen鈥� cement a reality and, together with academic colleagues, is now researching the mechanisms of carbonation of industrial waste from the atomic scale.

鈥淎lgae is also interesting. It has the ability to absorb carbon emissions, whilst having the ability to clean industrial wastewater as well,鈥� he says.

The funding from SOAR will go towards developing the Waste Transformation Research Hub, a collaborative industry鈥搖niversity approach to research future waste technologies for Australia鈥檚 circular economy.

鈥淭he funds will help me engage with partners, whether industry or academic, for this research. At the moment there is no cohesive national research hub on circular economy and waste processing. This is an opportunity for the University of Sydney 鈥� and for Australia 鈥� to lead the way internationally in waste transformation research,鈥� says Associate Professor Abbas.

The energy sector remains the largest contributor of carbon emissions in Australia. With growing concerns around Australia鈥檚 emissions reduction targets, Associate Professor Abbas鈥檚 waste research could become a key influencer in pushing Australia in the right direction towards these goals.
