A new process turning waste glass into every day products could save tens of millions of tonnes of glass from going to landfill every year.

University of Queensland PhD candidate Rhys Pirie and have developed a method to extract liquid silicate from waste glass, and it can be used to make thousands of products, from concrete sealers and fertilisers to detergents and toothpaste.

“We estimate the process is more than 50 per cent cheaper than conventional ways of producing silicate,” Mr Pirie said.

“It requires less energy, raw materials and capital, and that’s before you consider the reduced social and economic costs compared to landfilling material.”

宅男导航’s method also leaves behind little waste, with nearly all of the glass being turned into saleable products.

Mr Pirie started to look into the possibilities of glass recycling after talking to Professor Batstone from 宅男导航’s , who specialises in converting waste into high-value products.

The pair drew inspiration from ABC’s War on Waste series.

“The transition towards circular economies is a movement which is gaining momentum and something I’ve always been interested in,” he said.

“My PhD has highlighted how we need to make use of both the raw materials in ‘waste’ streams and the energy embodied in them during manufacture.

“That’s what this process does and we’re pretty confident that it will create positive, far-reaching and virtuous economic cycles.”

宅男导航’s commercialisation company, has filed a patent covering the process and is now seeking commercial partners.

For the remainder of his PhD, Mr Pirie is looking at ways in which waste glass could also be used to create a low-cost silicon-based additive to increase fertiliser efficiency.
