Innovation Milestone: Envit Ltd. secures 4th patent on a novel and innovative remediation solution

A major milestone for Envit Ltd.! Our 4th patent has just been published, marking a significant leap forward in sustainable soil remediation and land restoration.

We’re proud to announce that Envit Ltd. has officially published its 4th patent, titled: "REMOVAL OF ARSENIC, ANTIMONY AND TOXIC METALS FROM CONTAMINATED SUBSTRATE"

Abstract: The present invention relates to a batch process for washing of soil, sediment, sludge and other Fe-containing substrates to remove toxic metalloids, notably As and Sb, and toxic metals, notably Pb, Zn, Cd, Cu, Ni, Hg, Mo, Mn, Tl, Cr, Cs, Sr, Th and U. The present invention aids in treatment of waste washing and rinsing solutions generated from washing the substrate contaminated with toxic metalloids and with toxic metals. The invention furthermore aids in reclamation of washing and rinsing solutions, reagents and other materials, and in activation of recycled chelator for more efficient removal of toxic metals from substrate.

Why it matters: This patent marks a significant leap forward in environmental remediation. By addressing both the decontamination of toxic metals and metalloids-laden substrates and the sustainable treatment and reuse of washing solutions, this innovation offers a more efficient, circular approach to managing industrial and legacy contamination. It helps move us closer to cleaner soil, safer water, and a more resilient environment.

This patent, a proud moment for the Envit team - pushing the boundaries of sustainable remediation science!

Envit’s breakthrough remediation technology is redefining how we restore contaminated land. This closed-loop, emission-free solution eliminates toxic metals and metalloids from polluted soils without generating wastewater, all while preserving the integrity of the soil as a natural resource.

Versatile and scalable, the technology can be applied to a wide spectrum of contaminated sites -including agricultural and urban soils, rice fields, brownfields, military sites & conflict zones, and even excavated or historically disposed soil. It’s a next-generation tool for the green transition, supporting sustainable land use, circular resource recovery, and climate-smart soil management - worldwide.

Reclaim. Reuse. Remediate. — Restoring Degraded Land for a Greener Transition Worldwide
