CREW Carbon engineers wastewater treatment facilities to permanently sequester CO2 by optimizing pH and alkalinity management using natural minerals. This process improves operational efficiency, reduces costs associated with conventional neutralization, and enhances safety for facility operators. The resulting carbon removal is continuously measurable, offering durable and scalable climate action for carbon buyers.

Problem
Wastewater treatment plants face increasing pressure to reduce their carbon footprint while maintaining efficient and safe operations. Traditional methods for pH control and alkalinity optimization can be costly and pose safety risks to operators. Additionally, there is a need for verifiable and permanent carbon dioxide removal (CDR) solutions in the wastewater treatment sector.
Solution
CREW Carbon offers a technology that integrates enhanced weathering into wastewater treatment processes, enabling permanent carbon dioxide removal through the capture of CO2 as stable bicarbonate. By introducing natural minerals into the treatment process, CREW enhances treatment efficiency and safety while reducing operational costs associated with conventional pH control methods. The process involves a closed-system approach with input and output sensor arrays for precise monitoring, reporting, and verification (MRV) of carbon removal. This approach allows wastewater facilities to valorize the CO2 removal benefits, improve biological treatment stability, and meet stringent permit regulations.
Target Audience
CREW Carbon targets municipal and industrial wastewater treatment facilities seeking cost-effective, safe, and verifiable carbon dioxide removal solutions, as well as organizations looking to purchase high-quality carbon credits.
