Coal Combustion Products

Clean Earth's proposed technology for beneficial reuse of ash is based upon a combination of physical and chemical stabilization that binds and isolates contaminants within the treated mass.  These processes use common treatment reagents including cements, pozzolans, and cementitious mixtures, such as lime and ash mixtures to form hardened materials that impede the transport of many contaminants.

Clean Earth has successfully applied this technology and demonstrated the recycling and beneficial reuse of coal combustion residues and ashes and municipal waste incinerator ash residue combined with numerous sources of alkali by-products used to form cementitous grout materials that can be recycled for numerous upland applications. Final beneficial reuses have included landfill closure and capping material, alternative grading and/or daily cover material, remediation and redevelopment of contaminated industrial sites (brownfield sites) and the reclamation of abandoned strip mines.
