Development of new-generation autoclaved cellulose fibre-cement composites using alumina-silica rich industrial waste. Autoclaved cellulose fibre-cement (FC) composites are used for construction purposes globally. Alumina-silica rich industrial waste, such as fired clay bricks and tiles, are proven to be highly reactive under autoclaving conditions and are generated in abundance either during the production process or demolition of buildings worldwide. The project aims to utilise this renewable ....Development of new-generation autoclaved cellulose fibre-cement composites using alumina-silica rich industrial waste. Autoclaved cellulose fibre-cement (FC) composites are used for construction purposes globally. Alumina-silica rich industrial waste, such as fired clay bricks and tiles, are proven to be highly reactive under autoclaving conditions and are generated in abundance either during the production process or demolition of buildings worldwide. The project aims to utilise this renewable waste for the manufacture of improved FC products. The successful outcomes of the project could allow a new range of cost-effective building products which need less energy for their manufacture, to be realised for both developed and developing countries.Read moreRead less
An optimally integrated treatment process for food waste and wastewater to maximise sustainability in a decentralised treatment plant. Decentralised small scale treatment plants are required for remote communities, resort locations and 'rural residential' developments. This project has access to an operational plant in urban Brisbane serving 21 houses, the first development in urban Australia with full approval for an onsite treatment facility. The plant has been designed to treat an integrate ....An optimally integrated treatment process for food waste and wastewater to maximise sustainability in a decentralised treatment plant. Decentralised small scale treatment plants are required for remote communities, resort locations and 'rural residential' developments. This project has access to an operational plant in urban Brisbane serving 21 houses, the first development in urban Australia with full approval for an onsite treatment facility. The plant has been designed to treat an integrated kitchen waste and blackwater stream, with upstream anaerobic digestion that reduces the survival of wastewater pathogens and generates soluble organic carbon for the biological removal of nitrogen and phosphorous. The project will produce expertise in decentralised treatment systems, including the development of two PhD students in this area.Read moreRead less
Feasibility of biological hydrogen production from biomass wastes using activate sludge microorganisms. This study will focus on biological hydrogen production from biomass wastes, not only because hydrogen is a clean and high efficient energy, but also because it can be a process for waste treatment. The research is aimed at examining the feasibility of biological hydrogen production from an organic waste stream by hydrogen producing bacteria isolated and enriched from pretreated digested activ ....Feasibility of biological hydrogen production from biomass wastes using activate sludge microorganisms. This study will focus on biological hydrogen production from biomass wastes, not only because hydrogen is a clean and high efficient energy, but also because it can be a process for waste treatment. The research is aimed at examining the feasibility of biological hydrogen production from an organic waste stream by hydrogen producing bacteria isolated and enriched from pretreated digested activated sludge. The overall goal is to get better understanding of the biochemical mechanisms, metabolic pathways effecting on the intermediate and end-products, leading to high hydrogen productivity and yield.Read moreRead less
Functional Analyses of Bacteria Involved in Enhanced Biological Phosphorus Removal from Wastewater. The abundant growth of blue-green algae in global waterways is substantially caused by phosphorus (P) release from wastewater treatment plants. This environmental drama can be mitigated against by P-accumulating bacteria partitioning the P inside their cells. The P-removal process often fails, but since the metabolism of P-accumulating bacteria is unknown, remedial actions are based on conjecture ....Functional Analyses of Bacteria Involved in Enhanced Biological Phosphorus Removal from Wastewater. The abundant growth of blue-green algae in global waterways is substantially caused by phosphorus (P) release from wastewater treatment plants. This environmental drama can be mitigated against by P-accumulating bacteria partitioning the P inside their cells. The P-removal process often fails, but since the metabolism of P-accumulating bacteria is unknown, remedial actions are based on conjecture. This fundamental, knowledge-generating project will address this shortfall and will develop methods to evaluate the activity of P-accumulating bacteria, contributing substantial understanding of their metabolism. The final goal is to promote stable, reproducible P-removal from wastewater.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. The project aims to understand and eliminate the occurrence of such discoloration and improve the quality of the Visy product ....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. 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.

The use of chiral pharmaceutical compounds to characterise sewage treatment processes and sewage contamination of surface waters. Contamination by poorly treated and untreated sewage can severely degrade the quality of Australian surface waters. However, the behaviour of organic chemicals during conventional sewage treatment processes remains poorly understood. Furthermore, raw sewage pollution is generally not distinguishable from properly discharged treated sewage effluent by current analytica ....The use of chiral pharmaceutical compounds to characterise sewage treatment processes and sewage contamination of surface waters. Contamination by poorly treated and untreated sewage can severely degrade the quality of Australian surface waters. However, the behaviour of organic chemicals during conventional sewage treatment processes remains poorly understood. Furthermore, raw sewage pollution is generally not distinguishable from properly discharged treated sewage effluent by current analytical methods. The proposed research will provide a chemical marker for characterising treatment processes and identifying untreated sewage pollution. This will help to identify sources of such pollution so that they may be corrected. A principal outcome of the research will be the improved ability to protect Australia's valuable surface waters from sewage pollution.Read moreRead less
