Encapco’s organic-based asphalt emulsion is used to immobilize lead in contaminated soil. Unlike other fixation or stabilization technologies, which physically bind contaminants in the soil matrix, Encapco’s emulsion is capable of chemically fixating lead. The Encapco process employs a chemical binding reaction in addition to encapsulation to meet regulatory leaching tests. The Encapco process has been evaluated on a number of contaminated materials ranging from silty sand from a quarry site, contaminated sand from a steel mill, and a foundry sand.
