Microbial infestation of pre-painted steel building materials: chemical and microbial characterization, model development and control strategies. Coated steel building materials are a multi-billion dollar Australian industry. Microorganisms form slime layers on those materials, which are unsightly and reduce their energy benefits. The project will identify the problem organisms, the factors that facilitate their growth and will develop novel biofilm resistant, functional building materials.

Synthetic phenazines for enhanced biogas production from renewable and non-renewable resources. Methane (biogas) has a large role to play in meeting the energy needs of the human race globally whilst reducing greenhouse gas emissions. Microbial communities are responsible for biogas production from non-renewable (coal) and renewable (food waste) resources. This project seeks to: increase biogas yields by redirecting electron flow towards biogas producing microbes using electrochemically active p ....Synthetic phenazines for enhanced biogas production from renewable and non-renewable resources. Methane (biogas) has a large role to play in meeting the energy needs of the human race globally whilst reducing greenhouse gas emissions. Microbial communities are responsible for biogas production from non-renewable (coal) and renewable (food waste) resources. This project seeks to: increase biogas yields by redirecting electron flow towards biogas producing microbes using electrochemically active phenazines; understand the molecular mechanism by which phenazines increase biogas yields; and, assess the environmental consequence of phenazine application to coal seam gas production and anaerobic digestion of food waste. Phenazines are likely to emerge as a safe and cost-effective technology for improved biogas generation.Read moreRead less
Novel bioderived and biodegradable wood plastic composites from wastes. This project pioneers the development of high performance wood plastic composites from polyhydroxyalkanoates (PHAs) generated from pulp and paper waste. The key innovations are: developing a new bioderived and biodegradable high performance wood fibre composite with improved melt flow leading to better binding; and making direct use of PHA-rich biomass so avoiding the cost and environmental burden of polymer extraction.

The key innovations are: developing a new bioderived and biodegradable high performance wood fibre composite with improved melt flow leading to better binding; and making direct use of PHA-rich biomass so avoiding the cost and environmental burden of polymer extraction. The project aims to lead to new products and more diverse markets for the Australian forestry industry and maximise Australia’s competitive advantage in biomass-based product development.Read moreRead less
Immobilized biocatalysts on selected filter media to control odour emissions from wastewater treatment and composting facilities. Odour is one of the common problems faced by wastewater and solid waste industries as a result of public complaints about poor local air quality. Although odour removal technologies exist, they encounter a number of problems. The lack of harsh chemicals required for the proposed technology means there is no wastewater stream to treat. This will have an impact on the r ....Immobilized biocatalysts on selected filter media to control odour emissions from wastewater treatment and composting facilities. Odour is one of the common problems faced by wastewater and solid waste industries as a result of public complaints about poor local air quality. Although odour removal technologies exist, they encounter a number of problems. The lack of harsh chemicals required for the proposed technology means there is no wastewater stream to treat. This will have an impact on the reduction of chemicals disposed to the environment, preventing unnecessary contamination of land and water resources. The lower space requirement of the technology will free up land, formerly required for large biofilters, for other uses including civic amenities.Read moreRead less

Summary
A novel autotrophic biological nitrogen removal process driven by ammonia-oxidising archaea and anammox bacteria. This project will provide fundamental support to the development of more sustainable nitrogen removal processes. This would bring considerable benefits to the Australian wastewater industry and could potentially influence the way that biological nutrient removal plants are designed and operated.
In-situ electrochemical generation of caustic and oxygen from sewage for emission control in sewers. This project aims to deliver an innovative technology that controls the emission of notorious compounds from sewer networks using chemicals directly produced from sewage, with electricity being the input. Compared to existing methods, this technology provides a much safer and more environmentally friendly solution, at less than 50 per cent of the cost.

Removing a Key Barrier for Autotrophic Nitrogen Removal from Wastewater. This project aims to develop new technology to enable stable autotrophic nitrogen removal from domestic wastewater. The technology selectively suppresses the growth of nitrite-oxidising bacteria using a by-product of wastewater treatment – free nitrous acid. Maximising energy recovery from wastewater and providing greenhouse gas neutral water services have been the targets of water utilities in Australia and worldwide.

The use of in planta digestion for pretreatment of biofuel feedstock. This project will develop crop plants that overcome the current technical and economic impediments to the use of crop residues as biomass for large scale biofuel production. This innovation will position rural Australia at the forefront of global efforts to develop ligno-cellulose-based fuel ethanol industries and help meet mandatory renewable energy targets and the growing demand for alternative transport fuels. This project ....The use of in planta digestion for pretreatment of biofuel feedstock.

Treatment of secondary sludge using free nitrous acid to enhance performance and economics of a wastewater treatment plant. This project will deliver a new process that utilises a by-product of wastewater treatment to reduce the environmental and financial costs of wastewater treatment. The project will significantly reduce waste materials discharged from wastewater treatment plants and enhance bioenergy recovery from wastewater, in addition to improving effluent quality.
