TRANSCRIPT

An Australian-Canadian research team has developed a method to transform mine waste, known as "tailings," into fertile soil suitable for growing crops like maize and sorghum.

Typically, #tailings are laden with toxic heavy metals and are stored to prevent environmental contamination. Converting this lifeless waste into arable #soil could save billions in storage costs and mitigate the risks of storage facility failures. The researchers used a synchrotron particle accelerator called the Canadian Light Source to accelerate reintroducing soil microbes to the tailings, making them suitable for plant growth.

This innovative technique may offer a sustainable solution for mine waste and help restore damaged soils affected by over-farming and climate change.
