About

Vaulted Deep is a Houston-based carbon removal company that injects organic waste (biosolids, manure, paper sludge, food and agricultural residues) deep underground using slurry injection technology for permanent storage. In 2025 it delivered over 23,000 tonnes of verified CO₂ removal and signed major offtake agreements with Microsoft (4.9 million tonnes through 2038) and Google (50,000 tonnes by 2030). The company was spun out of Advantek Waste Management in 2023 and operates its Great Plains Facility in Hutchinson, Kansas.
