Self-Assembling Microemulsion Catalysts to Remedy Ecotoxicants
VeruTEK Founder, John Collins presented Designing Green, Sustainable Solutions - Self-Assembling Microemulsion Catalysts to Remedy Ecotoxicants at the Air and Waste Management Association NES Fall 2010 Conference. The Road to 2020 – Building Blocks to a Green Future – The Decade Ahead The Air & Waste Management Association – New England Section (A&WMA-NES) provided a neutral forum for institutional, regulatory and private sector professionals to discuss current developments in policies, initiatives and programs related to Greenhouse Gas (GHG) emissions, Air Toxics, New Source Review and “Green” Technology.

Congressman John Larson came to visit VeruTEK Technologies Bloomfield CT headquarters. Mr. Larson and his associates were happy to learn about VeruTEK's commitment to green technology. VeruTEK educated Congressman Larson on advances in microemulsion catalysis, surfactants and nanotechnology research that is taking place right in the heart of New England. Historically remediation of oil spills, wastewater, contaminated soil and groundwater has been limited to many archaic technologies and unsustainable forms of clean up. Congressman Larson and his team were happy to see the progress VeruTEK is making in providing green solutions for the marketplace. Dr. John Collins, Dr. George Hoag and VeruTEK employees were able to meet congressman Larson and provide a tour through the newly expanded state of the art laboratory. We hope he visits again soon and spreads the green technology word!
VeruTEK has been a pioneer in the design of Microemulsion Catalysis systems for the safe, green destruction of contaminants in the environment. Microemulsion catalysis is essential to overcome organic chemical reagent incompatibility and is well documented in organic synthesis. Problems with existing technologies for the remediation of Non Aqueous Phase Liquids (NAPLs) exist because the oxidizing reagents (oxidants and catalysts) are in an aqueous phase and the pollutants are predominantly in the organic phase. This is also true of biocatalytic remediation reactions when NAPLs are present.
VeruTEK’s S-ISCO® patent pending technology which combines plant surfactants, oxidants, and green catalysts has been shown to be effective in destroying oils, coal tar, creosote, chlorinated solvents and other toxic contaminants associated with NAPLs. Beyond environmental remediation, microemulsion systems have many industrial and commercial applications such as catalysis, medical, personal care and agricultural uses.
VeruTEK and EPA scientists (see Hoag et al. Degradation of Bromothymol Blue by “Greener” Nanoscale Zero-Valent Iron Synthesized Using Plant Polyphenols, Royal Society of Chemistry Journal of Materials Science and Nadagouda et al. Green Synthesis of Au Nanostructures at Room Temperature Using Biodegradable Plant Surfactants, American Chemical Society Crystal Growth and Design) and others (see Fallis et al. (2009), Locus-Specific Microemulsion Catalysts for Sulfur Mustard (HD) Chemical Warfare Agent Decontamination, JAMS) have documented the basis and rationale for the design of oxidative and reductive catalysts for the destruction of environmental toxins. These publications represent central advances in environmental technology that will be built upon for many years to come. These papers clear up some of the confusion and dogma still prevalent in the marketplace- yes, surfactants and oxidants can be combined in stable formulations – and provide a green technology platform to build upon.
Plant – based surfactants – dilute hydrogen peroxide solutions provide one example of new microemulsion catalytic systems as a framework for designing green solutions to many environmental problems, including industrial, commercial and residential cleaning products. For example, VeruTEK designed a nontoxic surface washing agent to destroy beach tar balls and ocean oils which is presented below. The practical application of this technology is an alternative to the toxic dispersant used in the Gulf of Mexico oil spill. Instead of sinking much of the crude oil while increasing aquatic toxicity, a VeruTEK surface washing agent would provide a green eco-friendly approach to destroying crude oil through emulsification and oxidation (Microemulsion Catalysis) and to additionally take advantage of natural destruction from sunlight and wave action.

DI Water (left), and S-ISCO® Treatment (right)
Surfactant-Enhanced In Situ Chemical Oxidation (S-ISCO®) batch tests were conducted on weathered crude oil and tar ball contaminated Pensacola Florida beach sand. Jars were filled with 400 grams of contaminated beach sand, followed by the S-ISCO® treatment chemicals. The jar on the left acted as a control and contained beach sand with 400 mL of deionized water, and the jar on the right was treated with S-ISCO® chemicals. Within fourteen days, oil was removed from the beach sand and destroyed in place using VeruSOL®-Marine 200, hydrogen peroxide, and GreenCAT, a green synthesized catalyst.

Full-scale PCE DNAPL remediation using S-ISCO®Rasmussen, Larsen, Christensen, Riis, Jensen (NIRAS A/S, DK) Terkelsen (Capital Region, DK) Hoag, Bytautas, Guite (VeruTEK Technologies, USA)
VeruTEK Technologies, Inc. (VeruTEK) performed a large-scale green remediation field test. The test focused on treatment of subsurface coal tar at a former Manufactured Gas Plant with VeruTEK's Coelution TechnologyTM, surfactant-enhanced in-situ chemical oxidation (S-ISCOTM). The test results exceeded expectations. Greater than 4 times the test designed soil contamination was destroyed and the test achieved a sustainable reduction in groundwater contamination.
