Wastewater treatment technology that removes carbon while improving plant performance.
CREW Carbon is a climate technology company developing wastewater treatment solutions that permanently remove carbon dioxide while improving operational efficiency for utilities. Their process intensification platform integrates into existing wastewater treatment infrastructure using calcium carbonate dosing to optimize alkalinity, stabilize biological treatment, and reduce greenhouse gas emissions.
The company works directly with wastewater treatment facilities to improve settleability, reduce chemical usage, lower operational costs, and help utilities meet increasingly strict nutrient compliance regulations. CREW’s technology integrates into existing biological treatment systems without requiring large infrastructure overhauls, allowing facilities to deploy measurable improvements within weeks.
CREW Carbon is helping transform wastewater infrastructure into a climate solution. By combining wastewater process optimization with durable carbon removal, the company enables utilities to reduce costs and emissions simultaneously. Their closed-system measurement approach also creates highly verifiable carbon removal credits, positioning wastewater infrastructure as a scalable carbon management platform.
CREW Carbon creates impact by converting wastewater treatment systems into platforms for permanent carbon dioxide removal while simultaneously improving operational efficiency. Their approach replaces carbon-intensive treatment chemicals with naturally occurring minerals that enhance biological nutrient removal and lower plant emissions.
The company also reduces infrastructure strain and operational costs for municipalities by helping facilities defer expensive treatment plant upgrades. Through measurable and durable carbon removal integrated into existing utility systems, CREW contributes to climate mitigation, safer water systems, and more sustainable public infrastructure.
* Verified carbon dioxide removal projects deployed at wastewater facilities
* Reduced sludge volume index (SVI) by 50–70% in pilot deployments
* Helped utilities defer up to $350 million in infrastructure upgrades
* Reduced usage of sodium hydroxide, ferric chloride, sodium hypochlorite, and polymers
* Partnerships and buyers include Frontier, Watershed, Google, Salesforce, Autodesk, and JPMorgan Chase
