Landfills remain the main method of waste disposal in Australia and are a major source of groundwater contamination and greenhouse and odour emissions. This national research program will establish, under a wide range of Australian conditions, whether landfill phytocaps can meet regulatory performance criteria for water infiltration into and gas emissions from closed landfills more effectively, efficiently and sustainably than conventional capping systems. The project will produce (a) a scientific basis for site owners and regulators to agree on the performance and cost of conventional and phyto cover technologies, (b) a manual for the design and permitting of alternative covers and (c)improved scientific prediction of cover performance.Read moreRead less
Optimization of fuel consumption and vehicle emission by simulating the integrated air conditioning and engine controls. As public interest on environmental conservation increases, tougher regulations on vehicle emission and fuel consumption will be implemented causing likely further restrictions on fuel consumption while operating the air conditioning system. Currently air conditioning and engine systems are controlled by two separate programs and lack effective communication between each other ....Optimization of fuel consumption and vehicle emission by simulating the integrated air conditioning and engine controls. As public interest on environmental conservation increases, tougher regulations on vehicle emission and fuel consumption will be implemented causing likely further restrictions on fuel consumption while operating the air conditioning system. Currently air conditioning and engine systems are controlled by two separate programs and lack effective communication between each other. This research aims to gain better understanding of the quantitative effects of car air-conditioning systems on fuel consumption and various air pollutant emissions, and develop an integrated simulation tool that links the air conditioning, engine fuel consumption and emission to assist the achievement of optimum vehicle energy and emission management.Read moreRead less

Ecological renovation of constructed wetlands: changing state from algae to macrophyte dominated systems. Mars Confectionary's constructed wastewater treatment wetlands no longer purify its waste waters.

Sporadic influx of oxygen-rich rainwater / groundwater into subsurface waste sites induces dramatic biogeochemical changes which greatly influence the transport of contaminants present. In this project, fundamental knowledge gaps regarding the impacts of redox oscillations upon contaminant behaviour in these sediments will be addressed through a comprehensive program of field studies at a purpose-constructed experimental facility in an existing waste site, and complementary laboratory investigations. The intended outcomes are to improve understanding of contaminant mobility at the field-scale in these pervasive sites spread across the globe, and provide critical insight into their remediation using cost-effective techniques.Read moreRead less
Can real-time control deliver environmental flows to protect urban streams? Increased frequency and severity of both droughts and floods in a changing climate accentuate the already-severe global impacts on urban streams. This project aims to test a world-first approach to tackling this problem, using advances in real-time control technology.

Increased frequency and severity of both droughts and floods in a changing climate accentuate the already-severe global impacts on urban streams. This project aims to test a world-first approach to tackling this problem, using advances in real-time control technology. The approach facilitates a public-private co-management of water resources, offering simultaneous benefits in water supply, flood mitigation and provision of environmental flows to maintain healthy urban streams. It has the potential to revolutionise the way we manage water in cities, providing a model for the water industry around the world in adapting to a changing climate, turning excess and damaging urban runoff into a dual resource of water supply and environmental flows.Read moreRead less
