PHILADELPHIA, January 20th, 2024: Innovative Environmental Technologies, Inc. (IET) has renewed its license with Evonik Corporation for Evonik’s proprietary in situ geochemical stabilization (ISGS) technology. Under the terms of the agreement, IET has exclusive rights to ISGS technology in North America.
ABOUT THE TECHNOLOGY: In situ geochemical stabilization (ISGS) entails the use of modified permanganate solutions for the purposes of mass removal and flux reduction (i.e., NAPL stabilization). As the oxidant migrates through the treatment area, various geochemical reactions destroy the targeted compounds present in the dissolved phase. This causes a “hardening” or “chemical weathering” of the NAPL as it steadily loses its more labile components. This causes a net increase in viscosity of the organic material, which yields a more stable, recalcitrant residual mass. In addition, both the insoluble MnO2 precipitate that results from permanganate oxidation and other mineral species included in the ISGS formulation accumulate along the NAPL interface, physically coating the NAPL and thereby reducing the flux of dissolved-phase constituents of interest (COI) into the groundwater.
The technology provides both mass removal and mass stabilization. To achieve these objectives, the delivery of the ISGS material must be effectively distributed to the targeted zone(s) so as to facilitate the formation of the Birnessite-like crust. Birnessite is an oxide of Mn and Mg, along with Na, Ca and K with the composition:
(Na,Ca,K)(Mg,Mn) Mn6O14 . . 5H2O
“We believe that IET is best positioned to market and implement our very important technology. Over the past several years IET has manufactured and injected nearly 500,000 gallons of the ISGS to numerous sites across the United States and Canada.” said Bruce Lerner, CEO, PeroxyChem. ” In entering into this agreement we are pleased to further our strategic relationship with IET”
“The continuation of the ISGS technology license will allow IET to further broaden the suitable applications. The teaming relationship established between the technology owner and our company solidifies IET as a technology leader, providing both in-house patented technologies and licensed technologies. IET looks forward to providing the ISGS technology to broader targeted NAPL sources as an economical alternative to traditional stabilization processes.” said Michael Scalzi, President of IET.
