Land in parts of Australia valued in the hundreds of millions of dollars is currently contaminated by organic compounds to levels unsuitable for human health and safety . At many of these contaminated sites, the contamination is present as pure, separate phase oil that is trapped due to geology or other physical reasons. This remaining oil is a long term source of contamination, and is exceptionally difficult to remediate. The proposed research will investigate a novel and highly effective approach to destroying this contamination in the ground, helping to restore the value and utility of the land.Read moreRead less

Dual-membrane upgrading towards sustainable wastewater management. Water utilities in Australia have set aspirational targets for energy- and carbon-neutral wastewater services by as early as 2030. However, these two aims are often incompatible because of excessive aeration energy consumption and substantial greenhouse gas emissions in wastewater treatment plants. This project aims to develop a novel biotechnology that enables simultaneous bioenergy recovery, cost-efficient nitrogen removal and ....Dual-membrane upgrading towards sustainable wastewater management. Water utilities in Australia have set aspirational targets for energy- and carbon-neutral wastewater services by as early as 2030. However, these two aims are often incompatible because of excessive aeration energy consumption and substantial greenhouse gas emissions in wastewater treatment plants. This project aims to develop a novel biotechnology that enables simultaneous bioenergy recovery, cost-efficient nitrogen removal and mitigation of greenhouse gas emissions, thus bringing multifaceted benefits to wastewater management. The project will provide strong support to the Australian water industry in their endeavour to achieve economically and environmentally sustainable wastewater services.Read moreRead less

This project aims to develop a novel technology of flue gas desulphurization for alumina industry. The successful completion of this project will provide a practical solution to the SOx emission problem in alumina refineries. Specifically, we aim to make use of the waste causticiser sludge discharged during the causticisation of the liquor streams and the used filter aid after the polishing filtration of the refinery pregnant liquors as reagent to remove SOx emitted by the power house and the alumina calciners. We also aim to recover some alumina during the process of flue gas desulphurization thus further reducing the cost of air pollution control.Read moreRead less

For the ....The quality of prisons for Indigenous persons in custody: determining how prison impacts on culture, community life and recidivism. International experience with Indigenous prisoners suggests prison need not be the void it presently is for too many traditional Aborigines and Torres Strait Islanders. Through working in partnership with prisoners from primarily remote communities and two State jurisdictions, a nationally applicable measure of Indigenous prison quality will be developed. For the first time, this research will provide insight into how Australian Indigenous culture and spirituality relates to prison quality and how prison can be more effectively applied in crime reduction. The ultimate national benefit is a contribution to better health and safety in remote Indigenous communities through custodial reform and reduced criminal justice costs through lower recidivism.Read moreRead less
