Summary

Vaulted deploys slurry injection technology to geologically sequester organic wastes for the purpose of permanent carbon removal. The TIRE facility is a biosolids injection well co-located with the City of LA's Terminal Island wastewater treatment plant. Over the course of its operations over ten years, the site has safely and effectively injected more than 450,000 tons of biosolids. Vaulted has not yet generated any carbon removal units (CRUs) from TIRE – activities are currently supported through tipping fees from the City of Los Angeles. Vaulted has waived fees for waste volumes over the 5-year baseline to enable the city to send additional volumes to the site. Vault only credits those volumes over the baseline.

How carbon is being removed

Biomass Carbon Removal and Storage (BiCRS) involves storing the carbon contained in waste biomass—organic material from living or recently living organisms. BiCRS works by halting or slowing the decomposition of biomass, enabling the carbon it contains to be stored long-term. This can be achieved by converting biomass into materials that decompose more slowly—such as biochar or bio-oil—or by storing it in environments where decomposition is slowed. For BiCRS to count as carbon removal, the biomass must be replenished to ensure additional carbon dioxide is drawn from the atmosphere.
