Short- and long-term mitigation strategies for acid and metalliferous drainage control from iron ore mine wastes. Acid and metalliferous drainage from mine wastes, caused by oxidation of sulfide minerals, particularly pyrite, are a critical environmental issue worldwide. Although options to retard sulfide oxidation exist, including encapsulation methods, chemical additives and inhibition of iron-oxidising bacteria, these suffer from long-term instability. The project aims to investigate mechanis ....Short- and long-term mitigation strategies for acid and metalliferous drainage control from iron ore mine wastes. Acid and metalliferous drainage from mine wastes, caused by oxidation of sulfide minerals, particularly pyrite, are a critical environmental issue worldwide. Although options to retard sulfide oxidation exist, including encapsulation methods, chemical additives and inhibition of iron-oxidising bacteria, these suffer from long-term instability. The project aims to investigate mechanistic approaches, using readily available mineralogical materials, to provide passivating conditions resulting in slowed oxidation rates. The project’s focus is on treatments for wastes from iron ore deposits which are of high economic significance to Australia. The outcome aims to be a treatment ‘pathway’ enabling practical waste rock treatment over the acid forming time-profile.Read moreRead less
Long-term acid rock and tailings drainage mitigation through source control. Effective long-term management of acid rock drainage (ARD) from sulfidic mine wastes in current, exhausted and legacy mine sites is of critical importance to communities and for sustainable mining. An optimised geochemical and microbial multi-barrier approach to long-term reduction of ARD to environmentally acceptable rates will be developed by this project.

Given the current demands on water in the Murray-Darling system and the systems national significance, the research will make a vital contribution to management of this critical national resource.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. Our preliminary research shows that new in vitro bioassays provide an ethical and cost effective alternative ....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. 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
Sustainable environmental management in Australian small firms. Small firms are the ‘backbone’ of the Australian economy but they can also have a significant negative impact on the environment. Helping them to increase their energy efficiency through an innovative intervention program will make a positive contribution to Australia’s environmental performance.
Carbon accounting for managed urban environments: creating a conceptual process-based model. This project will develop a process-based model of the carbon cycle of a complex urban system - Royal Botanic Gardens (RBG), Melbourne, and validate the model in the RBG, Sydney. It will test alternative means by which carbon emissions information may be reported to provide information that is useful for the decisions made by diverse stakeholders.
