With SE Qld on Level 5 water restrictions the need to reduce our demand on drinking water by increasing our reliance on recycled water is now urgent. To achieve this we need to ensure that the quality of our recycled wastewater is of a suitable and reliable standard. This project will assist the water industry in this endeavour by the developing monitoring techniques that can rapidly characterise and assess the effectiveness of wastewater treatment processes and the quality of the water derived from them. These methods will provide early warnings of potential 'upsets' in treatment plants that would otherwise result in poor quality effluents that would need to be discharged as waste rather than be recycled.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. 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
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.

Supply of potable water to Australia's major urban areas is a major challenge to growth and quality of life. Indirect potable reuse via membranes can address this issue, as it offers an inexpensive and sustainable water supply, as well as leveraging new water sources. However, the potential impact of the generated reject concentrates on aquatic and human health is potentially of large concern. Our project helps address this, by making reject treatment economically and environmentally much more sustainable, and thereby future-proofing the technology. In addition, it develops technology that can be used worldwide to treat other recalcitrant streams (e.g., hospital, tannery, pulp and paper), is highly scalable, and is low in operating cost.Read moreRead less
