The startup Vaulted Deep will inject human wastes into underground wells|Bestbudbrian|CC BY-SA 4.0

Industry titans Alphabet, Meta, Stripe, Shopify, and McKinsey Sustainability are investing $58.3 million in startup Vaulted Deep, which wants to store poop underground permanently to tackle climate change.

The corporations founded Frontier Climate, which brokered the deal aiming to sequester 152,480 tons of carbon dioxide by 2027.

How will it be done?
Vaulted Deep’s technology involves making organic waste like sewage and agricultural residue into sludge and injecting them into underground wells deep below the surface, preventing carbon emissions.

The technology, originally developed for waste disposal in oil and gas fracking, is now repurposed for environmental benefit.

While carbon dioxide removal holds promise, concerns persist regarding costs and its impact on the transition to renewable energy sources.
