Durable Carbon Removal

Vaulted Deep, a waste management company building subsurface infrastructure for organic waste, has secured a $35 million debt facility from Mediobanca to expand its national buildout. The financing, arranged by CFP Energy, is the largest publicly disclosed U.S. commercial debt deal in durable carbon removal to be secured by long-term purchase contracts.

The facility was supported by Vaulted’s waste service agreements and contracted carbon removal revenue, including offtakes with Frontier buyers backed by Stripe, Shopify, and Google. Vaulted delivered more than 20,000 tons of carbon removal to Frontier buyers in the first half of 2026, surpassing its 2025 total, and has increased weekly waste volume sixfold since 2023.

The new capital will help Vaulted advance more projects through its AI-Accelerated Site Development Platform, which combines proprietary technology and operating experience across site discovery, permitting, and injection operations. The facility adds a new source of growth capital alongside the $48 million in equity raised to date and its $8 million XPRIZE Carbon Removal award.
