Optimizing CO storage efficiency in Deep saline aquifers (DSA) involves improving each storage trapping mechanism, such as structural/stratigraphy, capillary/residual, mineral, and dissolution trapping mechanisms, while maintaining the reservoir integrity for long-term carbon capture and storage (CCS). These enhancements are driven by a series of geochemical reactions that favorably modify petrophysical, mineralogy, wettability, rock geomechanics of the rock, and dissolution of CO in aquifer fluid. Three different CO injection strategies have been identified and tested for optimizing CO storage and efficiency- Continuous CO injection (CCI), Water Alternating Gas (WAG), and Simultaneous scCO-brine Aquifer Injection (SAI).

However, these waste products are examples of "waste to wealth" products with a dual nature of being valuable products or disposable byproducts. PW contains various elements and compounds that can be extracted and used in the manufacturing or chemical processing industry.

Aboriginal and/or Torres Strait Islander adolescents in contact with the criminal justice system are a highly vulnerable group of Australians, with substantial unmet needs. There is limited evidence to inform culturally appropriate models of care that meet the social and emotional wellbeing needs of justice-involved Aboriginal and/or Torres Strait Islander adolescents.

Conclusion: While the negative effects of colonisation and trans-generational trauma continue, we propose renewed emphasis on improving access, cultural orientation and trauma-informed care, and a focus on the needs of young Indigenous Australians.
