PFASorb is a cutting-edge solution developed by Envirotreat to address the persistent issue of PFAS contamination in the environment. These synthetic organofluorine chemicals are characterized by their stability due to the carbon-fluorine bond, making them resistant to degradation. PFAS are found in various industries, favored for their hydrophilic and lipophilic properties. However, their stability leads to persistent environmental contamination, posing risks to human and wildlife health even at low concentrations. To mitigate these effects, Envirotreat has advanced its E-Clay technology, originally formulated in the 1990s, to create PFASorb a modified organoclay specifically designed for PFAS immobilization in soil and groundwater. Trials indicate a 98-99% reduction in leachability of PFAS pollutants. The integration of PFASorb with an E-Clay Permeable Reactive Barrier offers a sustainable and effective approach to managing PFAS contamination sites, as demonstrated at the Redditch Fire Station project.

ChromeSorb E-Clay is an advanced remediation technology developed to address the environmental challenges posed by Chromium (VI) contamination in soil and groundwater. Utilizing a unique chemical process, ChromeSorb effectively immobilizes both chromium's cationic (III) and anionic (VI) states, commonly found in contaminated sites. Its versatile application allows it to be used in permeable reactive groundwater barriers or as additives in soil stabilization, ensuring a one-step treatment procedure. Extensive testing demonstrates its capability in handling various concentration levels of chromium contamination. The E-Clay technology has proven effective in several practical scenarios, such as treating groundwater and surface water affected by chromium at industrial sites. This process helps control leachates and stabilizes chromium, presenting a reliable solution for environmental remediation projects.

E-Clay Technology is central to Envirotreat`s remediation solutions, leveraging chemically modified Smectite Clays to create a reactive medium adept at pollutant immobilization in soils and water. Over 150 projects have utilized this technology over the past two decades, showcasing its application in stabilization and barrier treatments. The transformation of these clays through Quaternary Ammonium Salts results in organophilic E-Clays proficient at absorbing diverse organic compounds. Additionally, integrating transition metals enhances their reactivity to aromatic hydrocarbons. While conventional QAS organoclays exhibit limited effectiveness with hydrocarbons like benzene, E-Clays employ varied chemical interactions, including Van Der Waals forces and covalent bonding, accommodating mixed waste treatments. Site-specific designs enable broad-spectrum pollutant treatment, further reinforced by the creation of pillared E-Clays.

StabOx is a range of modified E-Clays specifically designed to combine E-Clay stabilisation and chemical oxidation treatment technologies. Chemical oxidation offers significant benefits as the process rapidly destroys organic contaminants and significantly reduces contaminant mass into less harmful breakdown products.

ReDOC is a suite of advanced E-Clay products developed for the pre-treatment of waste streams, particularly soils, before they are sent to landfills. These products are specifically engineered to handle wastes with high levels of leachable Dissolved Organic Carbon (DOC), aiming to meet Waste Acceptance Criteria (WAC) necessary for disposal in stable, non-reactive, or hazardous waste landfills. Dissolved Organic Carbon represents all covalently bonded carbon atoms in organic molecules that can pass through a special 0.45 µm filter. The wide variability in DOC, due to its dependency on pH and other pollutants, poses a challenge in waste treatment. For example, poly-aromatic hydrocarbons (PAHs) exhibit increased leachability in alkaline conditions. ReDOC products leverage proven E-Clay stabilization technology to address this issue without resorting to cementitious materials, thus avoiding potential drawbacks and ensuring compliance with WAC requirements. This approach provides an effective solution for reducing DOC levels in waste prior to landfill disposal.

The Envirotreat Stabilisation Technology is a chemical and physical immobilisation technique incorporating the use of specially modified E-Clays and other specialist additives.The E-Clays can be applied for the effective remediation of contaminated soils enabling contaminated material to be brought back into effective use on a sound technical and commercial basis. The clays function by chemically reacting with and immobilising both inorganic and organic pollutants.

The Envirotreat Permeable Reactive Barrier System incorporates the use of modified pillared E-Clay technology. The E-Clay technology is designed to chemically immobilise pollutants of concern within contaminated groundwater.
