Dr. Anthony Halog is an academic researcher in the School of Earth and Environmental Sciences at the University of Queensland, Australia. His research focuses on the sustainability of human-nature complexity through understanding the nexus of material and energy systems. Over the years, he has been working on the foundation and industrial applications of Circular Bioeconomy, Greening Supply Chains, Life Cycle Management, Green Economy, Sustainable Operations, Life Cycle Sustainability Assessment (LCSA), and Resource Management. He is leading the Research Group of Industrial Ecology and Circular Economy that endeavours to provide service/expertise for industry/government clients (e.g., agri-food-energy systems) in transforming existing linear system-based value chains towards circularity, which enhances their resource efficiency & productivity, creates added value products from wastes, and reduces emissions into the environment for more sustainable consumption and production. Currently, he is leading a 4-year project on "Optimization of Refuse-Derived Fuels to Decarbonize Electricity Sectors and Achieve Nationally Determined Contribution (NDC) Targets in Indonesia" funded by Australia's DFAT International Climate Change Engagement Program. In the USA, he was one of the chief investigators of US-funded projects of ~$7.7 million, out of which $841,281 was awarded to his specific research on life cycle sustainability assessment of biomass-based technological systems. His qualification in environmental life cycle assessment (LCA) has been certified by the American Centre for Life Cycle Assessment (ACLCA) since January 2009. He has been serving as Australia-Germany Research Ambassador (DAAD-Australia) since September 2019.
