Study of molecular interactions between wood pitch fixatives and components of wood pitch. Wood resins, released in pulping, agglomerate in the papermaking process to cause pitch deposits. These deposits adversely affect paper machine efficiency and product quality and limit further recycling of process water. This project aims to investigate the interactions between the components of the wood resins and different fixatives using capillary electrophoresis and other techniques. This knowledge w ....Study of molecular interactions between wood pitch fixatives and components of wood pitch. Wood resins, released in pulping, agglomerate in the papermaking process to cause pitch deposits. These deposits adversely affect paper machine efficiency and product quality and limit further recycling of process water. This project aims to investigate the interactions between the components of the wood resins and different fixatives using capillary electrophoresis and other techniques. This knowledge will provide a better understanding of the role of the physical and chemical properties of the fixatives in fixing the different compounds in wood resins. Molecular modelling will be used to design new fixatives that will be selective to a mixture of wood resins.

At the forefront the development of clean, high-tech microwave drying technology and equipment, that is invented in Australia, will allow Australian companies to be forefront in this industrial area, to sell licences, designs, project management and equipment on international markets. This initiative will value-add plantation forests, reduce oil consumption and sequester CO2 in high value products.Read moreRead less
Improving the Processing of Timber from Plantation Forests: The Challenge of Managing Variability. Drying is a key step in processing timber. The increasing availability of plantation hardwood timber, with greater variability in its properties than previous resources, presents an opportunity to take advantage of the development of better mathematical techniques for process optimization and better drying and mechanical models for timber to address this challenge. This project will produce optimi ....Improving the Processing of Timber from Plantation Forests: The Challenge of Managing Variability. Drying is a key step in processing timber. The increasing availability of plantation hardwood timber, with greater variability in its properties than previous resources, presents an opportunity to take advantage of the development of better mathematical techniques for process optimization and better drying and mechanical models for timber to address this challenge. This project will produce optimized drying schedules, which are combinations of temperatures and humidities used during drying, to effectively dry plantation timber with variable properties, producing timber for high-value and appearance-grade end uses, such as flooring and furniture.Read moreRead less
Exploiting Resonance in Improving Dried Timber Quality by Optimizing Cyclic Drying Processes in Solar Kilns. Maximizing the value of final dried timber is essential for maximizing the economic benefits for Australia. If 10% of one million cubic metres of sawn hardwood timber produced annually in Australia increases its value raised by $500/m3, then the potential direct gain to Australian companies is over A$50 million per year. Multiplier effects include future applications to the drying of fo ....Exploiting Resonance in Improving Dried Timber Quality by Optimizing Cyclic Drying Processes in Solar Kilns. Maximizing the value of final dried timber is essential for maximizing the economic benefits for Australia. If 10% of one million cubic metres of sawn hardwood timber produced annually in Australia increases its value raised by $500/m3, then the potential direct gain to Australian companies is over A$50 million per year. Multiplier effects include future applications to the drying of foods, where the potential benefit in using solar kilns is a reduction in CO2 emissions of at least a million tonnes of CO2 per year, and a potential cost reduction of A$38 million per year.Read moreRead less

Australia is in a highly competitive position with regards to market supply but this cannot be taken for granted. This research seeks to understand the complex biology of sandalwood using the latest genomic and molecular technologies. This knowledge will be applied through directed, marker-assisted tree selection and improved plantation management. Ultimately we are developing a highly advanced production system with which Australia can lead Sandalwood production. Sandalwood plantations use a variety of native perennial hosts, increase biodiversity, help manage underground water resources and address carbon sequestration demands.Read moreRead less
Indian Sandalwood: genetic and oil diversity, and oil biochemistry of the Australian germplasm collection. The main aim is to improve the commerciality of the sandalwood industry in tropical Australia through smarter tree selection and breeding by development of knowledge of oil quality and quantity, oil biochemistry and DNA marker-assisted selection of the germplasm collection available in Australia.
