Biocontrol of foaming in activated sludge plants with bacteriophages. Activated sludge systems are the most widely used processes for treating wastewater in Australia. Yet most eventually suffer from episodes of bulking and foaming, where high levels of biosolids leave the plant with the treated waste, representing serious pollution hazards. Attempts to solve these problems have met with limited success.The highly novel biocontrol method proposed here will provide a specific, environmentally fri ....Biocontrol of foaming in activated sludge plants with bacteriophages.

Enhancing the productivity of wastewater desalination. Climate change is causing reduced rainfall over much of populated Australia. New technology to enable membrane desalination of wastewater treatment effluent will be developed to provide secure reliable water supplies for Australian (and international) urban and regional communities. Application of the technology to Western Treatment Plant at Werribee will provide up to 10 gigalitres/year of recycled water to the local agricultural, business ....Enhancing the productivity of wastewater desalination. Climate change is causing reduced rainfall over much of populated Australia. New technology to enable membrane desalination of wastewater treatment effluent will be developed to provide secure reliable water supplies for Australian (and international) urban and regional communities. Application of the technology to Western Treatment Plant at Werribee will provide up to 10 gigalitres/year of recycled water to the local agricultural, business and tourism precincts. The economy, community and environment will benefit due to reduced use of potable, river and ground water. Wide application of this technology to wastewater and brackish water will lead to similar benefits and an environmentally sustainable Australia.

Microbiology of Autothermal Thermophilic Aerobic Digester (ATAD) Systems for Biosolids Disposal in Wastewater Treatment Systems. The disposal of biosolids from wastewater treatment plants is expensive and troublesome. ATAD systems utilise microbes and are claimed to overcome many of the problems of more conventional disposal methods. Two have been installed in plants in central Victoria. However, virtually nothing is known about their microbiology. The study will determine which microbial popula ....Microbiology of Autothermal Thermophilic Aerobic Digester (ATAD) Systems for Biosolids Disposal in Wastewater Treatment Systems. The disposal of biosolids from wastewater treatment plants is expensive and troublesome. ATAD systems utilise microbes and are claimed to overcome many of the problems of more conventional disposal methods. Two have been installed in plants in central Victoria. However, virtually nothing is known about their microbiology. The study will determine which microbial populations are present and responsible for biosolids digestion, how these populations might change with changing operational conditions, and whether these changes in populations relate to production of odors. This information will enable these digesters to be better managed and operated.Read moreRead less
Building green roads with gasified municipal solid waste composites. This project aims to develop gasified municipal solid waste composites as a novel and green road material. This project expects to generate new knowledge on the fundamental properties of the developed waste composites when used as road subgrades and bases, through experimental study, physical modelling, numerical simulation, and field trials.

This project aims to develop gasified municipal solid waste composites as a novel and green road material. This project expects to generate new knowledge on the fundamental properties of the developed waste composites when used as road subgrades and bases, through experimental study, physical modelling, numerical simulation, and field trials. Expected outcomes include understanding the mechanical behaviour of these waste composites under static and cyclic loads, development of versatile constitutive models and numerical analysis tools, and determination of their optimal performance. Benefits include diversion of municipal and demolition wastes from landfills and the development of sustainable materials and technology for future roads.Read moreRead less

Nanoengineered, Encapsulated Catalysts from Fly Ash Waste. This project aims to deliver advanced catalysts and novel catalyst synthesis methods from the use of iron-rich fly ash, an otherwise abundant valueless waste with projected steady growth across Australia and globally. The as-synthesised catalysts are expected to be applicable to and exhibit excellent activity in the production of green hydrogen and renewable bio-fuels from lignocellulosic waste. These efforts are significant and benefici ....Nanoengineered, Encapsulated Catalysts from Fly Ash Waste. This project aims to deliver advanced catalysts and novel catalyst synthesis methods from the use of iron-rich fly ash, an otherwise abundant valueless waste with projected steady growth across Australia and globally. The as-synthesised catalysts are expected to be applicable to and exhibit excellent activity in the production of green hydrogen and renewable bio-fuels from lignocellulosic waste. These efforts are significant and beneficial in restoring the manufacturing capability of Australian industry, driving Australian industry towards the development of a circular economy for the appropriate management of solid waste, as well as for a seamless introduction of renewable and clean energy sources to address the pressing climate change.Read moreRead less
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

Chemicals in compostable food contact paper packaging materials. The aim of this project is to understand the presence of persistent chemicals in recyclable and compostable food contact materials (FCMs). These types of products are destined for recycling or biowaste streams that bridge the gap from take-make-dispose and into a circular economy.

The aim of this project is to understand the presence of persistent chemicals in recyclable and compostable food contact materials (FCMs). These types of products are destined for recycling or biowaste streams that bridge the gap from take-make-dispose and into a circular economy. Currently, the knowledge of the chemicals in these products is limited but we need to ensure that they are safe and do not unnecessarily contaminate resource recovery streams. It is expected that this project will develop a framework that could be used by industry and government to prevent chemicals of concern persisting in a circular economy, providing environmental and economic benefits through reduced risk of chemical exposure and unnecessary remediation costs.Read moreRead less
