Nano-engineered catalysts for sustainable fuel production from waste . This project aims to address two major problems simultaneously-reducing the burden of non-recyclable waste currently going to landfill in Australia, and offsetting Australia’s reliance on imported diesel to support industry and transport needs. While approximately 95% of diesel consumed in Australia is imported, vast quantities of carbon-based waste ends up in landfill. Municipal Solid Waste (MSW) is a mixture of plant-based ....Nano-engineered catalysts for sustainable fuel production from waste . This project aims to address two major problems simultaneously-reducing the burden of non-recyclable waste currently going to landfill in Australia, and offsetting Australia’s reliance on imported diesel to support industry and transport needs. While approximately 95% of diesel consumed in Australia is imported, vast quantities of carbon-based waste ends up in landfill. Municipal Solid Waste (MSW) is a mixture of plant-based waste (including food, garden, paper, and wood) and fossil-fuel derived materials (plastics). Using an innovative and environmentally-sustainable catalytic process, the outcomes of this project are aimed alleviating Australia’s dependence on diesel fuel imports and better waste management solutions in Australia.Read moreRead less
Force Interactions in Packed and Fluidised Beds at Micro-Scale Operation. Industrial processing in the 20th century was about increasing size to gain benefit from economies of scale. This century, the focus is on micro devices like lab-on-a-chip and high speed computer processors that deliver their product directly to the consumer. There are significant obstacles facing this new technology. Mixing is reduced due to laminar flow, and a large amount of energy is needed to move the fluid through su ....Force Interactions in Packed and Fluidised Beds at Micro-Scale Operation. Industrial processing in the 20th century was about increasing size to gain benefit from economies of scale. This century, the focus is on micro devices like lab-on-a-chip and high speed computer processors that deliver their product directly to the consumer. There are significant obstacles facing this new technology. Mixing is reduced due to laminar flow, and a large amount of energy is needed to move the fluid through such small devices. Particles are often added to improve mixing and heat transfer, but their presence adds to the energy requirements. This study will help us overcome these challenges. Read moreRead less

Selective generation of hydrogen from biomass and waste fuels. Biomass fuels account for 14% of global energy supply. This is likely to increase in future as the population increases, energy demand rises, cheap oil and coal reserves are depleted, and the effects of global warming become more readily visible. In Australia the development of a sustainable hydrogen economy is a national priority. The hydrogen economy could bring about improved energy security, substantially reduced greenhouse gas e ....Selective generation of hydrogen from biomass and waste fuels.

This project aims to develop innovative catalytic routes to the chemical recycling of mixed plastics for recovery of their molecular building blocks. Plastic pollution poses a significant threat to the Australian ecosystem. Efficient recycling technologies are urgently needed as Australia only recycles ~4% of its 3.4 million tons of mixed waste plastics. This project expects to design highly efficient catalysts for the stepwise breakdown of mixed polyolefin plastics into monomers for the subsequent manufacturing of virgin plastics in a circular economy, and to elucidate fundamental underpinning reaction mechanisms. Outcomes will stimulate the Australian waste plastic recycling industry, and minimise plastic accumulation in the environment.Read moreRead less
