Flipping the mattress: infinite polyurethane recycling by synthetic biology. Australia is covered in billions of tonnes of plastic and yet <10% is recycled today. Polyurethane (PU) is ubiquitous in our everyday lives, from lacquer coatings to elastane clothing to durable foam padding in car seats, cushions and mattresses. Currently, there are few avenues for PU recycling and much ends up in landfill e.g., a single mattress produces 15-20kg of PU foam waste. Luckily, biodegradation of PU can occu ....Flipping the mattress: infinite polyurethane recycling by synthetic biology. Australia is covered in billions of tonnes of plastic and yet <10% is recycled today. Polyurethane (PU) is ubiquitous in our everyday lives, from lacquer coatings to elastane clothing to durable foam padding in car seats, cushions and mattresses. Currently, there are few avenues for PU recycling and much ends up in landfill e.g., a single mattress produces 15-20kg of PU foam waste. Luckily, biodegradation of PU can occur naturally via various microbial means and from insects, like Galleria mellonella larvae. The overall aim of this research project is to understand plastic biodegradation and translate nature’s solutions into flexible and efficient synthetic enzyme technologies that can sustainably recycle commonly used PU foams.

Achieving Nitrite Shunt For Mainstream Sewage Treatment Using Human Waste. This project aims to develop a novel technology to achieve mainstream nitrogen removal from domestic sewage via nitrite shunt. Nitrite shunt can reduce energy consumption and promote energy recovery compared with the conventional nitrogen removal process. However, it is difficult to inactivate nitrite-oxidising bacteria, which is a key barrier for achieving nitrite shunt. By advancing the underpinning science and introduc ....Achieving Nitrite Shunt For Mainstream Sewage Treatment Using Human Waste. This project aims to develop a novel technology to achieve mainstream nitrogen removal from domestic sewage via nitrite shunt. Nitrite shunt can reduce energy consumption and promote energy recovery compared with the conventional nitrogen removal process. However, it is difficult to inactivate nitrite-oxidising bacteria, which is a key barrier for achieving nitrite shunt. By advancing the underpinning science and introducing a novel technology that innovatively harnesses a human waste, the project expects to remove the barrier. Expected outcomes will support the transformation of sewage treatment plants into net-zero energy generators. This should provide economic, environmental and energy benefits for Australia’s water and energy sectors.Read moreRead less

Circular clean energy regulation to solve the PV solar waste crisis. This project aims to design a new analytical framework, circular clean energy regulation, to fundamentally re-orient renewable energy law from the accelerated uptake of new technologies to a lifecycle approach. This re-orientation is urgently needed because while Australia is world leading in its uptake of rooftop solar, 90% of used panels go to landfill as hazardous waste. This project will explore how circular clean energy re ....Circular clean energy regulation to solve the PV solar waste crisis. This project aims to design a new analytical framework, circular clean energy regulation, to fundamentally re-orient renewable energy law from the accelerated uptake of new technologies to a lifecycle approach. This re-orientation is urgently needed because while Australia is world leading in its uptake of rooftop solar, 90% of used panels go to landfill as hazardous waste. This project will explore how circular clean energy regulation can improve the management of solar waste to reap the significant environmental, security and health benefits associated with solar recycling and critical mineral recovery. Expected outcomes include a new circular model of regulating renewable technologies, and better regulation and recovery of solar waste.Read moreRead less

Expected project outcomes will turn sewage sludge from an undesirable waste to a valuable resource. This should provide significant benefits for Australia’s renewable energy and resource sectors.Read moreRead less
Modelling of polydisperse particle-fluid reacting flows. Complex polydisperse particle-fluid reacting flows are widely practised in many industries where particle size distribution is wide and particle number is huge, yet the process design and optimisation are hindered by the lack of fundamental understanding of the complex reacting flows, particularly polydispersity and interactions. The project will tackle this specific challenge by developing a novel particle-scale mathematical model by inco ....Modelling of polydisperse particle-fluid reacting flows. Complex polydisperse particle-fluid reacting flows are widely practised in many industries where particle size distribution is wide and particle number is huge, yet the process design and optimisation are hindered by the lack of fundamental understanding of the complex reacting flows, particularly polydispersity and interactions. The project will tackle this specific challenge by developing a novel particle-scale mathematical model by incorporating new numerical techniques of interphase heat/mass transfers, polydispersity and computation speed-up; and applying it to two typical industry processes for demonstration. The outcomes will be applied across a range of industries of vital importance to Australian economic and technological future.Read moreRead less

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
The use of chiral pharmaceutical compounds to characterise sewage treatment processes and sewage contamination of surface waters.

Contamination by poorly treated and untreated sewage can severely degrade the quality of Australian surface waters. However, the behaviour of organic chemicals during conventional sewage treatment processes remains poorly understood. Furthermore, raw sewage pollution is generally not distinguishable from properly discharged treated sewage effluent by current analytical methods. The proposed research will provide a chemical marker for characterising treatment processes and identifying untreated sewage pollution. This will help to identify sources of such pollution so that they may be corrected. A principal outcome of the research will be the improved ability to protect Australia's valuable surface waters from sewage pollution.Read moreRead less

While there has been a dramatic increase in the use of submerged membrane systems in recent years, fouling of these membranes remains a major limitation to their more widespread use with the commonly used antifouling approach of bubbling with air exhibiting serious limitations. Low frequency vibration of submerged membranes appears to offer substantial benefits with regard to increased flexibility of operation (such as the ability for rapid turn up/turn down and the ability to minimise fouling in anaerobic systems)and is likely to further extend the use of membranes in water and wastewater treatment.Read moreRead less
