Regeneration of High Value-Added Materials from Spent Lithium-Ion Batteries. This project aims to develop scalable processing techniques for the regeneration of cathode materials and the production of high-purity alumina and graphene from spent lithium-ion batteries. The techniques reduce the cost and time of the processing of degraded cathode materials and increase the value of the spent battery materials (e.g., metallic aluminum and graphite) by converting them into high value-added specialty ....Regeneration of High Value-Added Materials from Spent Lithium-Ion Batteries. This project aims to develop scalable processing techniques for the regeneration of cathode materials and the production of high-purity alumina and graphene from spent lithium-ion batteries. The techniques reduce the cost and time of the processing of degraded cathode materials and increase the value of the spent battery materials (e.g., metallic aluminum and graphite) by converting them into high value-added specialty chemicals. The outcomes and further technology adoptions will extend the capacity of the Partner Organisation for producing specialty battery materials. The outcomes could help Australia’s battery industry switch to a more diversified pathway, which benefits the economic development of Australia in a long term.Read moreRead less
Fate of PAPs and short-chain PFAS in biosolids amended soils. Biosolids generated during wastewater treatment contain PFAS which are persistent, bioaccumulative and toxic. Application of biosolids to agricultural land may result in soil, groundwater and surface water PFAS contamination via leaching and run-off and pose unknown potential risk to soil health, crops and beneficial biota. This study aims to generate novel knowledge on the PFAS fate in biosolid amended soils, crops and toxicity to ke ....Fate of PAPs and short-chain PFAS in biosolids amended soils. Biosolids generated during wastewater treatment contain PFAS which are persistent, bioaccumulative and toxic. Application of biosolids to agricultural land may result in soil, groundwater and surface water PFAS contamination via leaching and run-off and pose unknown potential risk to soil health, crops and beneficial biota. This study aims to generate novel knowledge on the PFAS fate in biosolid amended soils, crops and toxicity to key soil and aquatic biota at environmentally relevant concentrations. This study is supported by Australian water and its allied industries, as it is important for them to ensure that biosolids application to agricultural land is an environmentally sustainable solution to the Australian farmers and communities.Read moreRead less
Dual-membrane upgrading towards sustainable wastewater management. Water utilities in Australia have set aspirational targets for energy- and carbon-neutral wastewater services by as early as 2030. However, these two aims are often incompatible because of excessive aeration energy consumption and substantial greenhouse gas emissions in wastewater treatment plants. This project aims to develop a novel biotechnology that enables simultaneous bioenergy recovery, cost-efficient nitrogen removal and ....Dual-membrane upgrading towards sustainable wastewater management. Water utilities in Australia have set aspirational targets for energy- and carbon-neutral wastewater services by as early as 2030. However, these two aims are often incompatible because of excessive aeration energy consumption and substantial greenhouse gas emissions in wastewater treatment plants. This project aims to develop a novel biotechnology that enables simultaneous bioenergy recovery, cost-efficient nitrogen removal and mitigation of greenhouse gas emissions, thus bringing multifaceted benefits to wastewater management. The project will provide strong support to the Australian water industry in their endeavour to achieve economically and environmentally sustainable wastewater services.Read moreRead less
