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/ash mixtures to form hardened materials that impede the transport of many contaminants.
Clean Earth has successfully applied this technology and demonstrated the recycling/beneficial reuse of coal combustion residues/ashes and municipal waste incinerator ash residue combined with numerous sources of alkali by-products used to form cementitous grout materials for the remediation and reclamation abandoned mine facilities.
