The Retek Process

The Retek Process is a well established on-site remediation approach that has been applied to a broad range of contaminated soils, dredge and other media, contaminated with substances classified as "hazardous" by the Environment Agency and US EPA.

At its simplest, the process involves mixing chemicals, reagents and binding agents, into the contaminated media in order to immobilize the contaminants within the treated material. The resulting chemical reactions and physical immobilization within the material destroys or binds the contaminants, and so removes the risks to humans, animals, and even plant receptors. The Retek Process has been approved by the EPA in the USA, and by the UK Environment Agency, and can be used to treat soils containing a wide variety of organic and inorganic contaminants.
