Metabolic engineering of sugarcane: production of a biodegradable bioplastic as a test-case. The aim of this project is to produce a commercially valuable bioplastic called PHB in transgenic sugarcane. This bioplastic has similar properties to petrochemically produced polypropylene, but is fully biodegradable. PHB has been produced in the model plant Arabidopsis thaliana at commercially viable levels. The expected outcome of high-level production of PHB in sugarcane would have significant ben ....Metabolic engineering of sugarcane: production of a biodegradable bioplastic as a test-case.

Condition monitoring and process control of injection molding. Injection molding has been widely used in automotive industry and improvement of the productivity and quality of the products is very important for the injection molding production to be internationally competitive. The aim of this project is to develop a condition monitoring and process control system to monitor the key parameters of the injection molding processes, to optimise the design and process conditions, and consequently, to ....Condition monitoring and process control of injection molding. Injection molding has been widely used in automotive industry and improvement of the productivity and quality of the products is very important for the injection molding production to be internationally competitive. The aim of this project is to develop a condition monitoring and process control system to monitor the key parameters of the injection molding processes, to optimise the design and process conditions, and consequently, to more actively control the processes. This will lead to an more reliable process, improved productivity and production of higher quality of moldings.Read moreRead less
Development of High Performance Mechanical Sorting of Plastics for Recycling. This research program aims to develop and test a range of high performance, mechanical in-process plastics sorting technologies in conjunction with Australia's lead recycling company. Currently, recycling techniques result in an insufficient purity and quality level, thus limiting the extent of recycling and opportunity for end product applications. Increasing the purity of recycled plastics and economics of recyclin ....Development of High Performance Mechanical Sorting of Plastics for Recycling. This research program aims to develop and test a range of high performance, mechanical in-process plastics sorting technologies in conjunction with Australia's lead recycling company. Currently, recycling techniques result in an insufficient purity and quality level, thus limiting the extent of recycling and opportunity for end product applications. Increasing the purity of recycled plastics and economics of recycling, without compromising throughput levels, will result in an increase in recycling rates and the range of applications of recycled plastics.Read moreRead less
DETERMINATION OF SUSCEPTIBILITY TO ENVIRONMENTALLY-ASSISTED CRACKING OF SMALL AND MICROSTRUCTURALLY VARIED REGIONS WHILE MAINTAINING FRACTURE MECHANICS VALIDITY. The proposed work seeks to develop an improved tool for more accurate design data and improved materials selection criteria for critical equipment and infrastructure maintenance in major Australian industries, where environmentally-assisted cracking is a serious concern (viz., marine, polymer/chemical processing, aeronautical, alumina m ....DETERMINATION OF SUSCEPTIBILITY TO ENVIRONMENTALLY-ASSISTED CRACKING OF SMALL AND MICROSTRUCTURALLY VARIED REGIONS WHILE MAINTAINING FRACTURE MECHANICS VALIDITY. The proposed work seeks to develop an improved tool for more accurate design data and improved materials selection criteria for critical equipment and infrastructure maintenance in major Australian industries, where environmentally-assisted cracking is a serious concern (viz., marine, polymer/chemical processing, aeronautical, alumina mineral processing and pulp-and-paper). A successful validation of the novel testing approach (namely, Spiral Notch Torsion Test (SNTT)) for evaluating the stress corrosion cracking (SCC) susceptibility of materials of practical interest that are difficult or impossible to adequately characterize by conventional tests, is as much a fundamental research challenge as its accomplishment will be industrially attractive.Read moreRead less
Development of Advanced Polymers from Recycled Industrial Plastics for Replacement of Virgin Resins. The main objective of this research program is to develop strategies and techniques to develop advanced polymeric materials obtained from recycled industrial plastics for replacement of virgin resins in industrial packaging.

The research will include a comprehensive study of the life cycle of the indus ....Development of Advanced Polymers from Recycled Industrial Plastics for Replacement of Virgin Resins. The main objective of this research program is to develop strategies and techniques to develop advanced polymeric materials obtained from recycled industrial plastics for replacement of virgin resins in industrial packaging. Studies show that only a very small amount of such plastic is reclaimed after industrial use. The research will include a comprehensive study of the life cycle of the industrial packaging products, development of new blends of the recycled resins, and the application of these blends to manufacture good quality injection moulded and blow moulded products including new plastic pails and containers for industrial use.Read moreRead less
Investigation of the variation and origin of contaminants present in recycled PET. Recycling and waste management are of ever increasing concern in today's consumer society and our capacity to recycle waste is directly reliant on our ability to lower contamination levels and ensure consumer safety.

Using novel analytical techniques, this project aims to characterise contaminants found in recycled PET and identify the source(s) of this contamination. Ultimately this will lead to a reduction in recycled PET contamination levels, and allow a more complete recycling process. The global objective being to generate enough relevant scientific data to assist Visy in its endeavours to achieve higher levels of environmental performances and sustainable product development.Read moreRead less
Novel injection moulded polymer substrates for solid phase applications. Solid phase organic reactions form the basis of many applications in drug design and development and medical applications. This project proposes the development of novel solid phase materials via control of novel insitu crosslinking and foaming processes and novel process molding control.

Improvement in Stress Corrosion Cracking Resistance of Stainless Steels in Environments Conducive to Localized Pitting Damage. Stress corrosion cracking (SCC) represents a serious threat to infrastructure exposed to chloride and caustic environments. The proposed project will characterize the chloride-SCC crack propagation parameters for a super duplex stainless steel, which is the material of construction for vessels for stripping vinyl chloride monomer in a PVC processing plant.

Stress corrosion cracking (SCC) represents a serious threat to infrastructure exposed to chloride and caustic environments. The proposed project will characterize the chloride-SCC crack propagation parameters for a super duplex stainless steel, which is the material of construction for vessels for stripping vinyl chloride monomer in a PVC processing plant. Alarmingly high numbers the welds (nearly 50%) in the vessel had suffered extensive pitting (which is a well-known SCC initiator) and SCC cracking. For the mitigation measures, the project will also investigate pitting and SCC susceptibility of weldments of alternative varieties of stainless steels, such as Zeron 100.Read moreRead less
