our vision: transform coal ash environmental liabilities into assets our mission: be the world standard for coal ash beneficiation since 2009, sonoash has worked to create a new, sustainable twenty-first century narrative for coal ash. there is a better way of processing and liberating the hidden value of coal ash. sonoash's proprietary technology allows for the processing of variable coal ash into a superior, uniform particle size cementitious pozzolan while liberating strategic metals as well as rare earth elements. the sonoash process will eliminate environmental liability considerations through total impoundment closure, change the coal mindset from only a single-use, one dimensional resource used only for generating electricity and heat to a multi-product sustainable resource. the beneficiation of millions of tons of coal ash in storage contains solutions and pathways to a healthier environment, greenhouse gas reductions and innovative strategic technologies.
