Microalgae have been gaining attention as a sustainable, less energy-intensive method for wastewater treatment. This involves growing them in the effluent, where they consume compounds containing nitrogen and phosphorus, as well as heavy metals, pesticides, and particular toxins. Microalgae view these as valuable nutrients, effectively removing pollutants from the water.
With electric vehicles predicted to represent 90% of all cars and light commercial vehicles on Australian roads by 2050, structural supercapacitors have the potential to revolutionise our transport by providing ‘mass-less’ energy storage, storing electrical energy in lightweight structural components of a vehicle’s body instead of in heavy, sole-purpose batteries. Dr Nisa Salim and her research team are working with multinational companies and Australian SMEs to demonstrate the exciting potential of these new supercapacitors, leveraging her collaborative relationships with a global academic and industrial network to take this cutting-edge research from the lab to the market place.
In a collaboration between researchers, the government, and production manufacturers, materials can be recycled and reformed into new products. We talk about three R’s: reduce, reuse, and recycle. Professor Veena Sahajwalla offers a fourth: reform. Instead of shipping waste offshore, we could be harvesting the high value materials in our waste. Each year, 50 million tonnes of e-waste is produced globally. In Australia, fewer than 1.5% of the 4 million computers sold a year are recycled. The total value of the resources embedded in them approximates $70 billion.
