We extract value from Coal Ash. 

We clean close impoundments.

We improve the bottom line.

SonoAsh offers a proven, patented process creating the socially responsible building products of tomorrow.  

SonoAsh was established to create and commercialize a comparable and enhanced uniform particle size cementitious pozzolan. These enhanced high performance cement pozzolans can be engineered to meet the infrastructure needs of the 21st Century.

The SonoAsh process provides an economically viable way of mining strategic metals and rare earth elements from Coal Ash impoundments.  

This new, 21st century iterative above ground mining is the answer to the global supply shortage of critical materials essential to modern day technological innovation. 

Environmental liability reduction and the clean closure of the Coal Ash impoundments is the ultimate objective of the SonoAsh process. 


It is not the strongest of species, nor the most intelligent that survives. It is the one that is most adaptable to change.
