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.
