Production of Biodegradable Polyhydroxyalkanoate Polymers using Advanced Biological Wastewater Treatment Process Technology. The aim of this project is to develop a sustainable process for producing biodegradable polyhydroxyalkanoate (PHAs)polymers from an innovative aerobic-anaerobic biological wastewater treatment process, ?treating? high strength food industry effluent. These biopolymers offer enormous potential for use as renewable and biodegradable thermoplastics.

The aim of this project is to develop a sustainable process for producing biodegradable polyhydroxyalkanoate (PHAs)polymers from an innovative aerobic-anaerobic biological wastewater treatment process, ?treating? high strength food industry effluent. These biopolymers offer enormous potential for use as renewable and biodegradable thermoplastics.
It is proposed to investigate two process configurations, namely the sequencing batch reactor and a continuous two step anaerobic-aerobic reaction system. These will be studied at bench-scale. The outcomes include:
1. Determination of the optimum microbial conditions and key growth
parameters for the production of PHA.
2. Optimisation of the process configuration, operating strategies
and operating conditions to maximise the
production of PHA.
3. Assessment of the influence of the feed composition (e.g. VFA)
on the PHA composition (PHB/PHV).

Extreme soil acidification and metal release risks from increasing drought. The project aims to study the effects of drought on pH and metal speciation in soils, and develop tools to assess current and future risks. Social and economic well-being depends on good soil and water quality. Climate change makes droughts more frequent and severe, which could cause soil acidification (pH<4) and metal release in many regions. The project will integrate experimental data on the effects of drought on soil ....Extreme soil acidification and metal release risks from increasing drought. The project aims to study the effects of drought on pH and metal speciation in soils, and develop tools to assess current and future risks. Social and economic well-being depends on good soil and water quality. Climate change makes droughts more frequent and severe, which could cause soil acidification (pH<4) and metal release in many regions. The project will integrate experimental data on the effects of drought on soil geochemistry with hydro-geochemical models, and apply these to national-scale predictions. The intended outcomes are improved management and preparedness for droughts and new research directions for geochemistry.Read moreRead less
East Australian climate extremes through the Holocene. The project aims to document climate variability in eastern Australia over the Holocene, the last 11,500 years. It seeks to develop Australia’s two highest-resolution Holocene climate records using novel techniques to infer past rainfall, temperature and evaporation. The project will combine the expertise of international drought and climate specialists with novel techniques developed by the Australian investigators to derive an unparalleled ....East Australian climate extremes through the Holocene. The project aims to document climate variability in eastern Australia over the Holocene, the last 11,500 years. It seeks to develop Australia’s two highest-resolution Holocene climate records using novel techniques to infer past rainfall, temperature and evaporation. The project will combine the expertise of international drought and climate specialists with novel techniques developed by the Australian investigators to derive an unparalleled record of drought duration, frequency and intensity. In particular, the project aims to determine the frequency, duration and causes of mega-droughts in eastern Australia, of which little is known. Expected project outcomes include improved decision making capacity for natural resource management, and planning.Read moreRead less
Microscale insights into ocean-scale processes: microbial behaviour as a driver of ocean biogeochemistry. Microscopic plankton regulate the ocean's chemical cycles, which ultimately support life on earth. However, the ecological interactions driving these processes are poorly understood. This project will use novel approaches to decipher the behaviours of marine microbes, providing a more complete perception of how ocean ecosystems operate and influence climate.
