This project aims to establish the genetic basis of polyethelene biodegradation (PED) by microbes from the gut microbiome of plastic-eating caterpillars. It will transform the active microbial PED genes into carefully designed synthetic microbes for efficient, safe and large-scale PED. The project will combine innovative functional microbial genetic tools and synthetic biology techniques with solid biochemistry and bioinformatics to produce translatable synthetic platforms containing key genes optimised for efficient PE waste removal. The outcomes will have the potential to transform the relative ineffective and expensive current methods for PE disposal into flexible, cost-effective and sustainable solutions applicable to multiple sectors.Read moreRead less
Preventing mining disasters: reducing the risk of tailings dam failure. This project aims to improve safety of tailings storage facilities (TSFs). Mineral processing produces waste called tailings, being mixtures of water and soil-sized particles. Tailings are stored on sites contained by embankments made from soil or a coarse component of tailings. Sections of the TSFs are partially saturated, have high concentrations of fine particles and physically change with age. Their resistance to earthqu ....Preventing mining disasters: reducing the risk of tailings dam failure. This project aims to improve safety of tailings storage facilities (TSFs). Mineral processing produces waste called tailings, being mixtures of water and soil-sized particles. Tailings are stored on sites contained by embankments made from soil or a coarse component of tailings. Sections of the TSFs are partially saturated, have high concentrations of fine particles and physically change with age. Their resistance to earthquake loading and liquefaction, and strength post-earthquake, arising from these properties are poorly understood and can not be quantified reliably so will be addressed here. Anticipated outcomes will be updated industry guidelines for the design and management of TSFs. Mines will benefit and failures will be prevented.Read moreRead less

Het-Crete: High-Grade Chemical-Treated Heterogeneous Recycled Concrete. Of over 20 million tons of mixed construction and demolition waste generated annually, only 5% is recycled and less than 1% is adopted for low-grade construction activities. This innovative research aims to solve Australia’s mixed construction and demolition waste disposal problem and lower its greenhouse-gas emissions at the same time.

This project aims to develop an innovative energy-neutral biological ammonium management strategy based on a novel anaerobic ammonia oxidation pathway. Ammonium-rich waste streams from urban and agricultural settings are a major cause of eutrophication and impose severe environmental burdens to human and ecological health. This project is expected to fundamentally change how we manage ammonium pollution, and will have immediate applicability to engineered bioreactors systems. This will provide significant benefits in supporting a wide range of industries that struggle with finding affordable and net-zero ways to manage ammonium wastes, providing an important step to reach global net-zero carbon emissions.Read moreRead less
Harnessing microbial respiration for pollutant degradation and natural gas production. This project seeks to exploit compounds produced naturally by microorganisms to develop a marketable green technology for environmental restoration and clean energy generation in Australia and abroad. Metropolitan and regional communities will benefit from improved environmental and human health and the economy will benefit from global application.
Green sample preparation technologies for analytical chemistry. This project opens new directions for the sample preparation of small molecules, nanoparticles and bacterial cells prior to analysis and will reduce pollution from chemical laboratories. The proposed 'green' analytical chemistry techniques will strengthen the position of Australia as a world-leader in separation science.
Accelerating clean automotive innovation: fundamental insights into alternative fuel combustion. To achieve the maximum efficiency from alternatively fuelled engines, better understanding and predictive models are needed for the major limiting factor in spark-ignition engine efficiency: knock. The project will address this gap, thereby accelerating development of better engines and strengthening national capacity in clean engine technology.
The New Oxidation Chemistry of Amines. Organic compounds containing nitrogen, including amines, are distributed throughout the atmosphere, where they are removed through oxidation reactions. Surprisingly little attention, however, has been directed towards the oxidation chemistry of amines. This problem is of growing importance as the leading technology for carbon capture from power stations involves amine solvents, which would potentially lead to large new sources of amines to the atmosphere. T ....The New Oxidation Chemistry of Amines. Organic compounds containing nitrogen, including amines, are distributed throughout the atmosphere, where they are removed through oxidation reactions. Surprisingly little attention, however, has been directed towards the oxidation chemistry of amines. This problem is of growing importance as the leading technology for carbon capture from power stations involves amine solvents, which would potentially lead to large new sources of amines to the atmosphere. This project will develop the new chemistry required to describe the oxidation of amines in the atmosphere, in order to better predict the impact of these under-studied molecules on air quality.Read moreRead less
