Nano-engineered catalysts for sustainable fuel production from waste . This project aims to address two major problems simultaneously-reducing the burden of non-recyclable waste currently going to landfill in Australia, and offsetting Australia’s reliance on imported diesel to support industry and transport needs. While approximately 95% of diesel consumed in Australia is imported, vast quantities of carbon-based waste ends up in landfill. Municipal Solid Waste (MSW) is a mixture of plant-based ....Nano-engineered catalysts for sustainable fuel production from waste . This project aims to address two major problems simultaneously-reducing the burden of non-recyclable waste currently going to landfill in Australia, and offsetting Australia’s reliance on imported diesel to support industry and transport needs. While approximately 95% of diesel consumed in Australia is imported, vast quantities of carbon-based waste ends up in landfill. Municipal Solid Waste (MSW) is a mixture of plant-based waste (including food, garden, paper, and wood) and fossil-fuel derived materials (plastics). Using an innovative and environmentally-sustainable catalytic process, the outcomes of this project are aimed alleviating Australia’s dependence on diesel fuel imports and better waste management solutions in Australia.Read moreRead less
Determination of the fate of dissolved organic nitrogen in biological nutrient removal (BNR) processes and development of appropriate treatment technologies. The aim of this project is to better characterise the dissolved organic nitrogen (DON) in sewage treatment plant influent, determine its fate in biological nutrient removal (BNR) plants, and to evaluate and develop an appropriate treatment technology.

The aim of this project is to better characterise the dissolved organic nitrogen (DON) in sewage treatment plant influent, determine its fate in biological nutrient removal (BNR) plants, and to evaluate and develop an appropriate treatment technology.
As a result of tightening effluent N licence requirements for sewage treatment plants, the dissolved organic nitrogen (DON) fraction has become extremely important. In many cases, the DON forms the major fraction of the effluent N, and is constraining further reductions in licence specifications, and in some cases it is the cause of failure to meet licence.
DON is refractory (un-biodegradable), very poorly characterised, its fate in conventional biological treatment processes not known, and its eventual impact on the environment unknown. Considering its importance, it is critical that these issues are addressed. This proposal intends to address some of them.
This project is an APA(I) PhD student project.Read moreRead less
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).

Development of a Nitrogen Removal Technology to Integrate with the Novel ‘EnRec’ Energy Recovery Sewage Treatment Process. The aim of this project is to develop a nitrogen removal technology to integrate with the novel energy recovery sewage treatment process, EnRec. EnRec is presently being developed as part of a collaborative R&D activity between the partners, and is partly supported by a Queensland Government (QSEIF) grant which was awarded in November 2002.

The aim of this project is to develop a nitrogen removal technology to integrate with the novel energy recovery sewage treatment process, EnRec. EnRec is presently being developed as part of a collaborative R&D activity between the partners, and is partly supported by a Queensland Government (QSEIF) grant which was awarded in November 2002.
One important issue yet to be addressed is how to achieve nitrogen removal in the EnRec process. One of the major differences between the EnRec process and conventional sewage treatment technology is that the main process reactor is anaerobic, thus eliminating aeration costs and enabling methane production. However, anaerobic treatment processes do not provide significant nitrogen removal, and thus it will be necessary to integrate a nitrogen removal technology with the main energy recovery process. This is the aim of this project.
The project is an APA(I) PhD student project.Read moreRead less
Photoelectrochemical control transport across a photoactive inorganic membrane fabricated by an in situ vapour phase hydrothermal method. Serious global fresh water shortage problems force us to recycle/reuse water. In Australia, this is an urgent issue due to our limited fresh water resources. Complete removal of biohazards (e.g., waterborne pathogens) from treated water is one of the most important aspects of safeguarding water recycling and has been the biggest obstacle for public acceptance. ....Photoelectrochemical control transport across a photoactive inorganic membrane fabricated by an in situ vapour phase hydrothermal method. Serious global fresh water shortage problems force us to recycle/reuse water. In Australia, this is an urgent issue due to our limited fresh water resources. Complete removal of biohazards (e.g., waterborne pathogens) from treated water is one of the most important aspects of safeguarding water recycling and has been the biggest obstacle for public acceptance. This project aims to tackle the issue by developing a highly efficient and effective new membrane technology that is capable of not just separating the biohazards from the source water but also in situ destroying them at the same time with low energy consumption and self cleaning features.Read moreRead less

This project aims to develop innovative catalytic routes to the chemical recycling of mixed plastics for recovery of their molecular building blocks. Plastic pollution poses a significant threat to the Australian ecosystem. Efficient recycling technologies are urgently needed as Australia only recycles ~4% of its 3.4 million tons of mixed waste plastics. This project expects to design highly efficient catalysts for the stepwise breakdown of mixed polyolefin plastics into monomers for the subsequent manufacturing of virgin plastics in a circular economy, and to elucidate fundamental underpinning reaction mechanisms. Outcomes will stimulate the Australian waste plastic recycling industry, and minimise plastic accumulation in the environment.Read moreRead less
