Four Australian among the world’s top ten universities best placed to solve the world’s biggest challenges

Four Australian universities were included in the world’s top ten universities contributing to the planet’s economic and social well-being.

The second Times Higher Education Impact Rankings shine a light on the vital research universities are conducting to tackle these issues, which include climate change, pollution and water scarcity.

Over the past 12 months alone, the world’s universities have developed solutions ranging from life-preserving breathing aids for coronavirus patients, to unleashing the potential of clean fuel-cell energy technology.

How bridges are built over water

Bridges built over water are marvels of engineering no matter how shallow or deep the water may be. But how exactly are these bridges built, particularly over deep water? It turns out there are three main techniques for the construction of such bridges and they are battered piles, cofferdams, and caissons.

Sanivation: putting waste to work

Sanivation is currently operating in Kenya, placing mobile toilets at households and sending a collection agent to pick up the buckets of waste twice a week. The waste is then taken to the Sanivation center, where a solar concentrator heats the biosolids over 70 degrees Celsius to remove pathogens in the waste. The waste is then further dehydrated in an agglomerator, and turned into charcoal briquettes that are used as fuel for burning.

e-Waste microfactory

Professor Veena Sahajwalla directs the Centre for Sustainable Materials Research and Technology (SMaRT) at UNSW Australia, delivering scientific and engineering advances in sustainability of materials and associated processes in collaboration with industry. Veena is revolutionising recycling science to enable global industries to safely utilise toxic and complex wastes as low-cost alternatives to virgin raw materials and fossil fuels. As Founding Director of UNSW’s Centre for Sustainable Materials Research and Technology, Veena and her team are working closely with industry partners to deliver the new science, processes and technologies that will drive the redirection of many of the world’s most challenging waste streams away from landfills and back into production; simultaneously reducing costs to alleviating pressures on the environment.
