Sewer corrosion reduction through model-supported ventilation control. Ventilation is one of the key technologies for sewer corrosion control. However, its design and operation are currently based on experience and empirical equations, often leading to unsatisfactory results.

Ventilation is one of the key technologies for sewer corrosion control. However, its design and operation are currently based on experience and empirical equations, often leading to unsatisfactory results. By integrating in-depth laboratory and pilot-sewer studies under defined conditions with extensive field investigations, this multidisciplinary project aims to develop critical models to predict the corrosion process in response to ventilation and dynamic wastewater and atmospheric conditions, enabling model-based sewer ventilation design and operation. The project also aims to deliver novel, field-demonstrated ventilation strategies. The project findings will be incorporated in the Australian ventilation design and operation guidelines.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.

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

Fundamental high temperature e-waste investigations for high-value products. This project aims to transform toxic electronic waste (e-waste) into value added metals and alloys, simultaneously segregating hazardous constituents and preventing the generation of harmful emissions during processing. Huge stockpiles of this fast growing waste stream are creating a crisis of quantity as well as of toxic ingredients posing serious health and environmental problems. Using atomic-level simulations, rapid heating, high temperatures (1000-1600 C) and selective thermal transformations, this project aims to establish novel pathways for a controlled transformation of e-waste. Microrecycling fundamentals on high temperature transformations of metals, plastics and oxides and other micro-level phenomena will be established.Read moreRead less

This project aims to develop a suite of leading-edge biotechnology solutions to enable the cost-effective production of liquid chemicals from biogas. This will create a much stronger economic driver for biogas production from organic wastes, by significantly increasing the value of biogas compared to its current use for power generation. With a multi-disciplinary approach, the project will substantially advance the fundamental science in the exciting and highly valuable area of anaerobic microbial conversion of methane, the least understood process in the global carbon cycle. This transformational research has a strong potential to create a new biotechnology sector producing high-value chemicals from methane, and will propel Australia to the forefront of sustainable resources research.Read moreRead less

This project aims to provide a holistic waste-to-resource remediation strategy for per- and poly-fluroalkyl substance (PFAS) contamination. This project expects to provide improved efficiency of remediation strategies for PFAS contaminated sites, to create new resource materials in construction and remediation from combinations of waste streams for the high-temperature destruction of PFAS. Expected benefits include inexpensive and effective treatment of PFAS contaminated sites, development of new markets around materials for environmental remediation and a mechanism to turn waste products into valuable resources, minimising the volume of wastes going to landfill. In addition, the environmental sector will benefit from improved implementation of policy around end-to-end and whole-of-life-cycle remediation of wastes and reclassification of wastes as high value resources suitable for construction and remediation.Read moreRead less

This project aims to enhance the removal of per- and poly-fluroalkyl substances (PFAS) compounds from municipal wastewater by making two simple amendments to standard wastewater treatment plants. Magnetite nanoparticles will be added to the treatment process, which adsorb PFAS compounds and reduce them to acceptable environmental levels. The resulting sludge will be dried and ashed in a simple and novel self-sustaining smoldering process which will render the captured PFAS to small ash, condensate and gaseous streams suitable for established destruction technologies. The project is expected to provide support to water utilities in achieving sustainable water treatment and result in environmental and social benefits to the community.Read moreRead less
