Summary

CREW removes carbon dioxide from the atmosphere via wastewater treatment systems, deploying fine-grained natural minerals like calcium carbonate in wastewater treatment systems. The deployment locations for this project are municipal wastewater facilitiies that serve the New England area and discharge directly into the ocean. Onsite, the feedstock is transferred into CREW’s dosing systems, and is dosed into the wastewater treatment reactors as a slurry. CREW’s system controls the rate of dosing to optimize process benefits and CDR.

How carbon is being removed

Marine carbon dioxide removal (mCDR) leverages the ocean's natural capacity to absorb and store carbon for thousands of years. These pathways use the biogeochemical and physical properties of the ocean and other bodies of water to capture carbon dioxide from the atmosphere or to permanently store carbon already contained within them. Approaches to mCDR include Ocean Alkalinity Enhancement and Direct Ocean Capture and Storage.
