A structural fill is an engineered fill designed to improve land for an intended end use. Typically, the land is unusable for the intended end use unless fill material is imported to raise the elevation to fit the desired design. Due to its homogenous particle size, predictable geotechnical characteristics, low unit weight, relatively high shear strength and ease of handling and compaction, coal ash is an ideal material for such fills. Charah Solutions is highly experienced in the use of coal ash, placing it and compacting it in accordance with approved ASTM design criteria.

Our proprietary EnviroSource fly ash beneficiation technology utilizes a thermal beneficiation process to achieve a higher quality material that meets ATSM and state specification requirements for use in the production of Portland cement and concrete. The proven technology reduces loss on ignition (LOI), ammonia, activated carbon, mercury and other contaminants making your formerly unusable fly ash in current production or legacy ash stored in ponds or landfills immediately marketable. As a result, the need for landfills, ponds and other disposal methods will be reduced.
EnviroSource eliminates previously uncombusted carbon and a wide range of contaminants in raw fly ash material. Importantly, not only does this technology create a sustainable use for coal combustion residuals (CCRs) and save valuable landfill storage space, it also reduces greenhouse gas emissions by serving as a supplementary cementitious materials (SCM) in place of Portland cement. It is estimated that for each ton of beneficiated fly ash there is one ton of potential CO2 emissions eliminated from the atmosphere.
Our EnviroSource fly ash beneficiation technology offers distinguishable benefits compared to alternative technologies in many ways as described below:
• Significantly lower cost profile
• Efficient footprint with self-contained environmental controls that can be deployed in weeks versus years.
• Modular design that can be scaled up or down to increase production based on market demand, allowing for the production of 40,000 to 200,000 tons per year
• Equipment can be used to meet demand without requiring high volumes for cost effectiveness or self-sustaining operation
• Can be installed at operating power plants, non-operating power plants or off-site
• Enables the processing of kiln dust to remove mercury for emissions regulations compliance.
Its most impressive distinction is its ability to deliver all of these benefits at a significantly lower cost profile than competing technologies, combined with an efficient footprint.
We offer high-quality Class C fly ash, high-quality Class F fly ash, MultiCem™ slag cement, MultiPozz™ pozzolan, bottom ash, gypsum and IGCC slag.

The main chemical components of fly ash are silica, alumina, iron and calcium oxides; all identical constituents of Portland cement. These common components contribute to added strength and durability of concrete.
Concrete manufactured with quality fly ash demonstrates the following technical advantages: added long term strength, durability, lower permeability, improved resistance to sulfate attack, increased pumpability and workability, and improved finish product quality. Additionally, concrete with fly ash is less expensive and more sustainable.
Our MultiPozz™ pozzolan, manufactured using our patented grinding technology, extends our complete portfolio of supplementary cementitious materials (SCMs), providing a continuous, reliable supply of pozzolan to concrete producers and other customers. It is produced by Charah Solutions’ proprietary grinding technology by converting natural pozzolans found in the earth, such as volcanic ash, into a highly desirable input for the production of Portland cement as it provides strength, durability, improved finish, and consistent performance in concrete. Because the supply of high-quality SCMs such as fly ash is limited in some regions of the country, the production of MultiPozz pozzolan, which meets ASTM and state specifications, is generating strong interest among concrete producers.
MultiPozz pozzolan is distributed through Charah Solutions’ unique MultiSource® materials network of nearly 40 nationwide sourcing locations which ensures a continuous and reliable supply of supplementary cementitious materials (SCMs), including quality Class C fly ash, Class F fly ash, pozzolan, bottom ash, gypsum and Integrated Gasification Combined Cycle (IGCC) slag, for ready mix concrete producers and other customers throughout the United States.
