Production, Fate and Transport of Cyanobacterial Toxins in Waterways. Australian waterways are under severe pressure from both large variation in precipitation patterns and various sources of contamination. In particular, the management of algal blooms costs Australians hundreds of millions of dollars a year.

Australian waterways are under severe pressure from both large variation in precipitation patterns and various sources of contamination. In particular, the management of algal blooms costs Australians hundreds of millions of dollars a year.

A HYBRID INTEGRATED SYSTEM FOR MUNICIPAL SOLID WASTE TREATMENT AND POWER GENERATION. The management of solid wastes is a major global environmental issue and the current practice of landfilling is not a sustainable solution. Biogasification of the organic fraction provides not only a means of waste treatment but also generates a source of energy in the form methane but current technologies are expensive due to the long degradation times. In this project we investigate an innovative waste tr ....A HYBRID INTEGRATED SYSTEM FOR MUNICIPAL SOLID WASTE TREATMENT AND POWER GENERATION. The management of solid wastes is a major global environmental issue and the current practice of landfilling is not a sustainable solution. Biogasification of the organic fraction provides not only a means of waste treatment but also generates a source of energy in the form methane but current technologies are expensive due to the long degradation times. In this project we investigate an innovative waste treatment system that will cut down the time required for processing wastes by a factor of 10 with considerable economic benefit. We will optimise the integration of this treatment system with a hybrid power generation system that utilises other renewable energy sources like solar and wind energy to deliver quality power at minimal cost.Read moreRead less
Development of a novel air pollution monitoring strategy - combining passive sampling with toxicity testing. Present approaches for monitoring risk of air pollutants are limited to grab sample analysis for specific pollutants using concentrations based on independent toxicological and/or epidemiological assessment of compounds. This approach does not allow for evaluation of mixtures or that a given compound may exert different toxic endpoints and is based on short sampling periods. This researc ....Development of a novel air pollution monitoring strategy - combining passive sampling with toxicity testing. Present approaches for monitoring risk of air pollutants are limited to grab sample analysis for specific pollutants using concentrations based on independent toxicological and/or epidemiological assessment of compounds. This approach does not allow for evaluation of mixtures or that a given compound may exert different toxic endpoints and is based on short sampling periods. This research aims to develop and evaluate a novel approach combining extraction of pollutants using time-integrated passive samplers and toxicological evaluation using rapid in-vitro and in-vivo assays. The outcomes provide inexpensive tools for sensitive assessment of pollutant effects and baseline data to derive intervention guidelines based on mixture toxicity.Read moreRead less

This project will improve our understanding of non-linear flow and fracture phenomena in porous media which is prerequisite for the development of new emerging technologies targeting the reduction of the greenhouse gas emission and development of effective waste and water management solutions including coal gasification, in-situ storage of natural and non-hydrocarbon gases, underground disposal of hazardous wastes and vadose zone remediation. The project will result in a dramatic improvement of the predictive tools for traditional ground water management, irrigation and petroleum recovery applications. It has the strength to place Australia in the forefront of these technologies. 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
A Novel Approach for Color and Degradation Control in Post Consumer Polyethylene Terephthalate During Recycling. Discoloration is a critical problem in the manufacturing of post-consumer polyethylene terephthalate (PET) polymeric products in which optical clarity requirement is high. The inherent weakness of the PET demands highly efficient stabilisation of this polymer.

Discoloration is a critical problem in the manufacturing of post-consumer polyethylene terephthalate (PET) polymeric products in which optical clarity requirement is high. The inherent weakness of the PET demands highly efficient stabilisation of this polymer. The project aims to understand and eliminate the occurrence of such discoloration and improve the quality of the Visy products. New multifunctional additives will be developed, which when added to PET during processing, will not only quench the discoloration reaction but also yield high quality products with excellent optical properties. This project is of substantial strategic importance to the Australian/global polymer processing and recycling industries.

Pollutants in wastewater undergo complex changes in sewers, leading to the production and release of odorous and corrosive compounds. Despite major efforts and expenditure by water utilities to mitigate these problems, odorous emissions from sewers are still commonly occurring in urban areas. Furthermore, the value of public assets is significantly diminished due to sewer corrosion, costing hundreds of millions of dollars a year in Australia alone. This project is a major joint effort by the Australian water industry and world-leading scientists to generate advanced knowledge and develop effective technologies for optimal odour and corrosion management in sewers, delivering large social, environmental and economic benefits.Read moreRead less
