Slide 3: The Situation
• An estimated 67 million tonnes of waste is generated by Australians alone every year • We are wasting finite resources by burying them as landfill • As the population grows, so does the waste problem The Situation • Current solutions to waste recycling are costly & labour-intensive • In fact, only
Slide 4: Oxidative Hydrothermal Dissolution (OHD)
Oxidative Hydrothermal Dissolution (OHD) A novel continuous, hydrothermal process to convert macromolecular organic solids into low molecular weight organic chemicals using only Critical Point 3,500 Liquid Pressure (Atmospheres) 374oC • Elevated temperature [+/- 270 ℃] 3,000 Pressure (psi) 200 2,500
Slide 5: OHD Process Advantages
OHD Process Advantages Technically straightforward & operates at industrially feasible conditions & rates Uses only water & oxygen, requires no exotic solvents or catalysts Readily achieves high to complete conversion of the starting solid with high recovery (typically 70-90+% C) of the products Env
Slide 6: The Approach
The Approach Build the reactor Validate the reactor Analyse products obtained from the reactor • Test known materials in the • Partner with specialists in OHD reactor such as coal, • Collate and interpret data building the reactor agricultural plant matter retrieved to advise on next • Test e-waste

Initial Findings OHD Processing ABS Plastic OHD Liquor Acrylonitrile 1, 3-Butadiene Styrene
Slide 10: What we confirmed
What we confirmed OHD technology successfully processes e-waste samples Removes plastics through oxidative dissolution , concentrating the major metals such as gold, tin, copper, iron and zinc Minor metals also identified were silver, barium, nickel, chromium, magnesium and manganese Converted plast
Slide 11: Next steps…
Next steps… Optimise e-waste, scale up & partnering Trial more different types of waste from diverse sectors, ie eg: ❖ Coal ❖ Solar Panels ❖ Batteries ❖ Textiles ❖ Anti-corrosive film Optimise the OHD process specific to different waste materials Determine OHD processed solids biodegradability via r
