Repurposing urban construction waste to create diverse wildflower meadows. Wildflower meadows have been planted extensively in European cities for aesthetic and biodiversity benefits. In SE Australia, they are stunning, but rare, features of critically endangered grassy woodlands because most native wildflowers cannot cope with intense grazing and high soil nutrients associated with agriculture. This project aims to develop a novel process for establishing native wildflower meadows in urban park ....Repurposing urban construction waste to create diverse wildflower meadows. Wildflower meadows have been planted extensively in European cities for aesthetic and biodiversity benefits. In SE Australia, they are stunning, but rare, features of critically endangered grassy woodlands because most native wildflowers cannot cope with intense grazing and high soil nutrients associated with agriculture. This project aims to develop a novel process for establishing native wildflower meadows in urban parks and degraded grassy woodlands by repurposing low nutrient mineral waste from the construction industry. It will have multiple benefits including restoring urban biodiversity, increasing people's mental well-being, developing new markets for recycled construction waste and reducing the amount of waste going to landfill.

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.

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. 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 reso ....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. 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
Upcycling of mixed plastics from bioprocessed municipal solid waste. This project aims to develop a scalable catalytic process that can sustainably upcycle mixed plastics from bioprocessed municipal solid waste into hydrogen and valuable carbon nanotube products.

This project aims to develop a scalable catalytic process that can sustainably upcycle mixed plastics from bioprocessed municipal solid waste into hydrogen and valuable carbon nanotube products. The process will integrate pyrolysis, reforming, and carbon growth technology into a single reactor, enabled by the rational design of multifunctional catalysts. Through computational process simulation and optimization, life cycle analysis, and techno-economic assessment, investment and operational costs at larger scale are anticipated to be greatly reduced. By mitigating mixed waste plastics from going to landfills, the project will also provide significant benefits to clean energy production and advanced material manufacturing in Australia.

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

Saving Nemo: Reducing animal use in toxicity assessments of wastewater. Every day, Australians produce ~5 billion litres of wastewater, which contains a cocktail of chemicals. Industries that discharge wastewater are required to assess chemical risks to the receiving environments by conducting whole animal direct toxicity assessments (DTA), which are expensive and pose an ethical dilemma.

Every day, Australians produce ~5 billion litres of wastewater, which contains a cocktail of chemicals. Industries that discharge wastewater are required to assess chemical risks to the receiving environments by conducting whole animal direct toxicity assessments (DTA), which are expensive and pose an ethical dilemma. Our preliminary research shows that new in vitro bioassays provide an ethical and cost effective alternative that could be incorporated into DTA programs if their ecological relevance can be demonstrated. This project will develop and validate a new and internationally significant suite of in vitro bioassays for incorporation into DTA programs, leading to more ethical, cost effective and improved environmental protection.Read moreRead less
