SonoAsh - A patented low-frequency sound separation technology designed to process impounded waste coal ash and create two valuable revenue verticals.

Thanks to its sonic technology, this solution turns coal ash waste into valuable assets, addressing the increasing needs of the cement production industry.

The cement industry accounts for roughly 5-8% of the world’s CO2 emissions. This solution offers an alternative to replace a portion of the ready mixture with an engineered, low carbon coal ash. It is the only patented, low-frequency sound application that can process wet, coal ash impoundments which have historically viewed as an unusable waste. While draining the existing coal ash impoundments, SonoAsh produces both a low carbon cement displacement but is also able to extract rare and strategic metals suitable for wind turbines, solar panels, strategic defence initiatives and more.

Key features

  • Reduces C02 emissions related to cement production by 30%
