Microsoft announced that it has invested in a long-term carbon dioxide removal (CDR) partnership with U.S.-based waste management company Vaulted Deep.
Under the 12-year deal, Vaulted will deliver up to 4.9 million tonnes of durable CDR through its permitted and effective waste management operations.
For the CDR company, this financial injection will fuel the expansion into new locations across the United States, scaling operations that contribute to meaningful climate, waste, and community results.
Vaulted Deep specializes in storing CO2-rich organic waste deep underground, creating a CDR pathway that locks in carbon dioxide emissions away from the atmosphere.
By injecting sludge-form waste material into stable underground geologic formations that are sealed by impermeable rock layers, Vaulted offers a solution not only to carbon dioxide pollution but also to methane emissions, and it provides a safe disposal space for environmentally dangerous trace contaminants like PFAS.
To source the waste feedstock, the company partners with municipalities, industrial operators, and agricultural producers, handling sludgy organic material like biosolids, manure, paper sludge, and food and agricultural residues that can’t be repurposed, recycled, or safely applied to land.
From these operations, Vaulted generates carbon removal credits that are certified by Isometric, delivering permanent carbon removal with a durability of more than 1,000 years.
So far, the company has processed more than 69,000 tonnes of organic waste, delivering 18,000 tonnes of carbon dioxide removal.

Beyond this positive environmental effect, its landmark Great Plains facility in Kansas has also brought on significant economic momentum to the region, funneling north of a million dollars to both local vendors and staff wages and employing more than 18 people full-time.
The deal with Microsoft comes after Vaulted enhanced this facility with new infrastructure upgrades in July 2025, a move that tripled the waste-processing capacity, enabling further job openings and local partnerships in the area.
Driven by a technology that is permitted in multiple U.S. states, Vaulted is looking to establish new partnerships that would align with its mission of tackling hard-to-manage organic waste.
