New soil remediation technologies
Veru-Tek Technologies has developed a spin on phytoremediation to clean up contaminated soil and groundwater on brownfield sites. Where traditional phytoremediation uses in situ plants, Veru-Tek uses extracts derived from plants, nanometals produced from plant extracts, and other natural substances to dissolve and oxidize contaminants (like coal tar, chemical solvents and petroleum byproducts) in place, turning them into non-toxic compounds. One method developed by Veru-Tek involves injecting a biodegradable substance similar to corn oil or coconut oil into the soil, where it breaks down pollutants into smaller molecules and reconfigures them into harmless byproducts. The company’s remediation methods have been demonstrated in a number of brownfield sites and provide an alternative to hauling contaminated material to landfills.
