Enhanced Prediction of Landfill Gas Emissions Through Geosynthetic Systems. Landfill gas represents an opportunity for electricity generation and carbon abatement: it need not be managed solely for environmental, health or safety risk reasons. However, our ability to predict gas collection and fugitive emissions from landfills capped with geosynthetics liners, in consideration of the myriad of factors that control these processes, is imperfect. Building on recent advances in unsaturated soil mec ....Enhanced Prediction of Landfill Gas Emissions Through Geosynthetic Systems. Landfill gas represents an opportunity for electricity generation and carbon abatement: it need not be managed solely for environmental, health or safety risk reasons. However, our ability to predict gas collection and fugitive emissions from landfills capped with geosynthetics liners, in consideration of the myriad of factors that control these processes, is imperfect. Building on recent advances in unsaturated soil mechanics, this project aims to conduct cutting-edge experimental and theoretical research to develop an experimentally-validated theory of gas migration through geosynthetics systems that is expected to lead to major improvement in performance and provide integrated design tools which are much needed but not currently availableRead moreRead less
Improved predictions of greenhouse gas transfers in landfill composite liner covers containing geomembrane defects. The Australian Greenhouse Office indicated that methane accounted for 85 per cent of the waste sector's annual greenhouse emissions in 2008, and stressed the need to undertake a range of activities to reduce these emissions. Models and theories derived from this project will address specifically the above issue leading to enhanced economic benefits.
Elastocaloric cooling systems for buildings and the built environment. This project aims to develop elastocaloric cooling systems that will find application in buildings and the built environment. The main aims of the projects are to establish a new technology capable of enhancing the efficiency of traditional cooling systems used for building applications and of reducing the contribution of structural and architectural components to the urban heat island effect. This work will be supported by a ....Elastocaloric cooling systems for buildings and the built environment. This project aims to develop elastocaloric cooling systems that will find application in buildings and the built environment. The main aims of the projects are to establish a new technology capable of enhancing the efficiency of traditional cooling systems used for building applications and of reducing the contribution of structural and architectural components to the urban heat island effect. This work will be supported by a new theoretical platform that will incorporate the elastocaloric cooling behaviour into the structural, thermal and energy performance of the building components, as well as by prototype testing. The outcomes of the project will lead to new building cooling technologies, increasing efficiency of traditional cooling building systems.Read moreRead less
Experimental and theoretical analysis of gas leakage rate through composite landfill covers due to geomembrane defects. The Australian Greenhouse Office indicated that waste emissions contributed 3.1% of net national emissions in 2001 with methane emissions from landfills accounting for 92% of total methane emissions from the waste sector, despite an increase in methane recovered from solid waste. It pointed out that the recent changes in waste management practices did not have an impact on repo ....Experimental and theoretical analysis of gas leakage rate through composite landfill covers due to geomembrane defects. The Australian Greenhouse Office indicated that waste emissions contributed 3.1% of net national emissions in 2001 with methane emissions from landfills accounting for 92% of total methane emissions from the waste sector, despite an increase in methane recovered from solid waste. It pointed out that the recent changes in waste management practices did not have an impact on reported methane emission levels and there is need to undertake a range of activities to reduce emissions from waste management activities. This project will address specifically the above issue by providing a new method of analysis to predict gas leakage rate and allow engineers to propose solutions to mitigate gas escapes.

Sustainable retirement villages for Ageing Australians. This project aims to deliver sustainable retirement villages to better accommodate older Australians and assess their effects on the growth of the retirement village industry. More organisations and governments globally are embracing sustainable development, but the Australian retirement village industry has been largely static and unresponsive; it has not yet met the green movement’s challenge to provide a sustainable living environment fo ....Sustainable retirement villages for Ageing Australians. This project aims to deliver sustainable retirement villages to better accommodate older Australians and assess their effects on the growth of the retirement village industry. More organisations and governments globally are embracing sustainable development, but the Australian retirement village industry has been largely static and unresponsive; it has not yet met the green movement’s challenge to provide a sustainable living environment for senior citizens. This project is expected to improve the living environment of retirement villages and the quality of life of older Australians.Read moreRead less

Life cycle assessment of greenhouse gas emissions for road infrastructure. This project aims to develop an assessment model to accurately measure greenhouse gas emissions that roads generate over their life cycle. The project will integrate recent methodological developments and practical advances from road construction and maintenance into its proposed assessment model. The expected outcome will be an assessment model and mapping tool which will visualise emissions levels and better map these e ....Life cycle assessment of greenhouse gas emissions for road infrastructure. This project aims to develop an assessment model to accurately measure greenhouse gas emissions that roads generate over their life cycle. The project will integrate recent methodological developments and practical advances from road construction and maintenance into its proposed assessment model. The expected outcome will be an assessment model and mapping tool which will visualise emissions levels and better map these emissions into the cost-benefit analysis of roads. This will make greenhouse gas reduction more effective and cheaper, and make the Australian infrastructure sector more competitive.Read moreRead less
Modelling and testing corroding reinforced concrete structures. The project aims to develop models and methods to enable the early detection of active steel corrosion.

The project aims to develop models and methods to enable the early detection of active steel corrosion. Most of Australia’s critical infrastructure is located on or near the coast in high saline conditions and is exposed to a high risk of reinforcing steel corrosion. Our ability to design and monitor such structures is crucial. The first part of the project aims to develop an innovative finite element model to improve the prediction of both active steel reinforcement corrosion and the time to concrete cracking in a chloride environment. It then plans to develop a non-destructive method, combining ultrasonic waves-based technology and acoustic emission, to detect active steel corrosion before any damage is visible on the structure.Read moreRead less

The characterisation of wastewater distribution patterns for the production of decision support systems for pathogenic risk analysis in water catchments. The project will aim to collate data and map base-level distribution patterns of molecular and microbial markers of human sewage and natural/agricultural contamination with reference to diurnal and seasonal fluctuations.

The project will aim to collate data and map base-level distribution patterns of molecular and microbial markers of human sewage and natural/agricultural contamination with reference to diurnal and seasonal fluctuations. These data will then be used to develop decision support systems that predict contaminant dispersion and identify high-risk contamination sources. The diurnal collection of data is expected to show significant variations in the measured parameters associated with time of day, light intensity and temperature. Mapping of the sewage and nutrient loads throughout the year will provide base line data for identifying potential hotspots for targeting system upgrades or improved management programs.Read moreRead less
