Vaulted Deep builds and operates subsurface infrastructure for organic waste disposal and permanent carbon removal, converting waste streams such as biosolids, manure, agricultural byproducts and paper sludge into a slurry injected thousands of feet underground via proven deep well injection technology. Spun out of industrial waste manager Advantek and headquartered in Houston, Texas, the company serves municipalities, industrial operators and agricultural producers from its Great Plains site in Hutchinson, Kansas and Terminal Island facility in Los Angeles. An AI-accelerated site development platform helps it identify, permit and operate new injection wells, with a site in Weld County, Colorado planned for 2027.
