Industry-Leading Non-Thermal Coal Ash Solutions
Discover how SonoAsh redefines coal ash processing solutions with a unique, patent-protected, low-emissions technology. By utilizing advanced sonication, we create two distinct but equally essential product verticals while bypassing the high energy costs of traditional methods.
Discover how SonoAsh redefines coal ash processing solutions with a unique, patent-protected, low-emissions sonication process. Our goal is to enable decarbonized next-generation infrastructure and become the world standard in coal ash beneficiation technology.
- Patented, non-thermal process.
- Life Cycle Analysis (LCA) conducted with third-party validation.
- Verifying that SonoAsh engineered coal ash has the lowest carbon footprint of any SCM.
- The global production of cement and concrete is estimated to be 9% of total global CO2 emissions (source: Scientific American, 2023).
- Using Coal Ash as a feedstock, SonoAsh creates an environmentally friendly green cement that minimizes the carbon footprint of cement production.
- SonoAsh can replace up to 50% of OPC (Ordinary Portland Cement) in concrete – eliminating an equal amount of emissions.
- Generates a unique source of REE metals.
Rare Earth Processing
SonoAsh is a recognized leader in rare earth processing, serving as one of 17 industrial sponsors in the US Department of Energy (DOE) CORE-CM recovery program. Our expertise is further validated by the DOE Advanced Manufacturing Energy Supply Chains (MESC) Technical Assistance award. As one of only 15 national awardees selected for future DOE funding applications, SonoAsh is at the forefront of securing domestic supplies of critical minerals.

Industrial Scale Ash and Rare Earth Recovery
The scale of the coal ash challenge is immense, and our non-thermal coal ash solutions are designed to meet it:
- 3Bn+ tons of impoundment ash are currently in storage.
- 746 sites across 43 states.
- 94% of storage sites are unlined, leading to potential groundwater pollution.
- Environmental Justice: Many sites are located near disadvantaged communities.
Our patented, low-carbon process converts these environmental liabilities into consistent, clean products and critical metal concentrates, delivering measurable industrial and environmental benefits.

The Sonicator Process: Waste-to-Value
Our proprietary technology delivers a consistent, clean ash product without the need for carbon-heavy thermal treatment.
- Non-Thermal Technology: Advanced rare earth processing and ash refinement without high heat.
- Energy Efficient: Lab-certified results that support a low-carbon emissions footprint.
- 80% Ash Yield: Converting waste into high-quality material for green cement solutions.
- 20% Critical Metals Concentrate: A proper waste-to-value solution for critical mineral recovery.

Benefits to the Ready-Mix Concrete Industry
By integrating our coal ash processing solutions, the concrete industry gains:
- Higher margins and lower raw material costs.
- Enhanced product reliability through engineered consistency.
- Lower emissions profiles for finished projects.
- Regulatory compliance with LEED building mandates and green procurement policies.
