The project aims to develop computational models to predict emissions of nitric oxides and carbon monoxide from sugar-mill boilers burning bagasse. Bagasse combustion does not contribute to greenhouse gas emissions and clean and efficient combustion of this fuel has become very important for the sugar industry and for Australia. The project combines the opportunity of direct boiler measurements by SRI with the modelling expertise at the University to develop combustion-kinetics models for these species. The models will be incorporated into the previously developed computational fluid dynamics - combustion code of the furnace to give the capability of emission prediction as a function of burner operating conditions and fuel parameters.Read moreRead less
A 60% efficient solar microconcentrator for electricity and hot water. The aim of this project is to develop a microconcentrator for deployment on house roofs that will produce both solar hot water and solar electricity with a combined efficiency above 60%. The system will have a low profile and will be nearly invisible from the street. The system will track the sun. Concentration will be accomplished by a mixture of refraction and reflection. About 20% of the sunlight will be converted to elect ....A 60% efficient solar microconcentrator for electricity and hot water. The aim of this project is to develop a microconcentrator for deployment on house roofs that will produce both solar hot water and solar electricity with a combined efficiency above 60%. The system will have a low profile and will be nearly invisible from the street. The system will track the sun. Concentration will be accomplished by a mixture of refraction and reflection. About 20% of the sunlight will be converted to electricity using lines of tiny solar cells, with the balance being converted to heat which is removed by cooling fluid and stored in hot water tanks.Read moreRead less

Innovative Grid-Connected, Small-Scale Wind Turbine Generators Offering Low Cost and Wide Operating Speed Range. Growing concerns about sustainability issues with fossil fuels have resulted in strong interest in wind power worldwide. Grid-connected inverters are an efficient way of utilising small wind turbines on domestic, farming or small commercial properties which have access to the power grid. Existing small-scale, grid-connected wind turbines are expensive and have a limited operating wind ....Innovative Grid-Connected, Small-Scale Wind Turbine Generators Offering Low Cost and Wide Operating Speed Range. Growing concerns about sustainability issues with fossil fuels have resulted in strong interest in wind power worldwide. Grid-connected inverters are an efficient way of utilising small wind turbines on domestic, farming or small commercial properties which have access to the power grid. Existing small-scale, grid-connected wind turbines are expensive and have a limited operating wind speed range. We are investigating new designs for low-cost wind turbine generators which can produce power over a wide range of wind speeds. The project should result in a greater application of small-scale wind generators in Australia and will lead to reductions in fossil fuel usage and greenhouse gas emissions.Read moreRead less
Thermal isolation: a novel pathway to transforming complex waste. This project aims to establish a novel pathway for transforming complex waste otherwise destined for landfill into valuable products and resources. By leveraging high temperature reactions, the team plans to thermally isolate useful carbons and silica from within automotive shredder residue (ASR) in situ, to produce activated carbon products and silica layers, and so completely recycle this bulk toxic waste for the first time. Suc ....Thermal isolation: a novel pathway to transforming complex waste. This project aims to establish a novel pathway for transforming complex waste otherwise destined for landfill into valuable products and resources. By leveraging high temperature reactions, the team plans to thermally isolate useful carbons and silica from within automotive shredder residue (ASR) in situ, to produce activated carbon products and silica layers, and so completely recycle this bulk toxic waste for the first time. Such innovative new pathways for separating out valuable materials from complex and toxic wastes offer industries an alternative low-cost and sustainable source of raw materials, while reducing pressures on landfills and finite natural resources.Read moreRead less
Improving biological nitrogen removal by enhanced mixing in non-aerated bioreactors. Mixing has been identified as a key factor in achieving enhanced performance out of existing and upgraded bioreactors. There is currently a poor understanding of the relationship between non-ideal flow and performance in wastewater treatment bioreactors. The project will determine this relationship and subsequently use it to show how reactor performance can be improved, providing first criteria by which mixing c ....Improving biological nitrogen removal by enhanced mixing in non-aerated bioreactors.

There is currently a poor understanding of the relationship between non-ideal flow and performance in wastewater treatment bioreactors. The project will determine this relationship and subsequently use it to show how reactor performance can be improved, providing first criteria by which mixing can be assessed, and second a systematic methodology for improving reactor performance by improving mixing.Read moreRead less

Provision of safe drinking water treatment using sustainable technology which can be applied in rural locations and emergency situations is the main aim of this project. A hybrid membrane process will be combined with solar energy for the removal of pathogens and trace pollutants such as uranium, fluoride, arsenic, boron and nitrates. The technology will be designed for remote community situations and hence be robust and low in maintenance. Using solar energy is a challenge for trace contaminant removal as the operating conditions vary with the power fluctuations, which presents a substantially different situation to grid power connection.Read moreRead less

Sequestration of CO2 with enhanced methane recovery from deep coal. Coal and gas represent the main energy source for the Australian and many other national economies into the foreseeable future. The continuing use of these critical resources requires that greenhouse gas emission issues be addressed. Any serious attempt to achieve reduced emission of CO2 from power generation requires sequestration as a necessary element. A plausible method for cost effective sequestration of large amounts of ....Sequestration of CO2 with enhanced methane recovery from deep coal. Coal and gas represent the main energy source for the Australian and many other national economies into the foreseeable future. The continuing use of these critical resources requires that greenhouse gas emission issues be addressed. Any serious attempt to achieve reduced emission of CO2 from power generation requires sequestration as a necessary element. A plausible method for cost effective sequestration of large amounts of CO2 is by geological fixing in deep, unminable coal. The key technological and scientific issues regarding capacity, rate, technical viability and site selection form the basis of this proposal.Read moreRead less
Methane and nitrous oxide emissions from sewers – understanding, modelling and mitigation. The research and industry partners will collaborate on this project to quantify, understand and mitigate emissions of methane and nitrous oxide in sewer networks. Both methane and nitrous oxide are potent greenhouse gases, and their emissions need to be accounted for and mitigated for the water industry to achieve greenhouse neutral water services.
