CREW Carbon Raises $25 Million to Scale Wastewater Treatment Technology with Verified Carbon Removal

CREW Carbon has closed an oversubscribed Series A funding round totalling $25 million, comprising $19 million in equity and $6 million in grant and other non-dilutive funding, to scale its patented wastewater treatment optimisation technology that simultaneously delivers measurable carbon dioxide removal. The round was led by Burnt Island Ventures with participation from AP Ventures, Sony Innovation Fund, Builders Vision, Kibo Invest, Idemitsu Ventures, New York Ventures, and existing investors including Counteract, ANIMO Ventures, Connecticut Innovations, Ponderosa Ventures and Echo River Capital. The financing positions CREW at the intersection of water infrastructure and carbon removal markets, two segments facing rapidly rising commercial demand.

 

The Problem CREW is Addressing

 

The wastewater treatment industry faces mounting pressure from tighter regulations and rising treatment volumes flowing through aging legacy infrastructure, which has driven treatment costs to double over the past 20 years. Utilities need solutions that can expand the capacity of existing systems without requiring massive capital investment, particularly as ratepayer affordability becomes an increasingly sensitive political issue. The structural mismatch between rising volumes and constrained capital budgets creates a strong market opportunity for technologies that improve performance within existing infrastructure footprints.

CREW's patented technology helps utilities get more out of their existing infrastructure by improving pollutant removal, boosting settleability and reducing reliance on costly chemicals. The combination increases plant capacity and efficiency while lowering both capital and operating costs. Because the solution integrates into existing wastewater processes, utilities can see measurable results within weeks rather than requiring multi-year capital projects, which significantly accelerates the time to value compared to traditional infrastructure upgrades.

The Dual-Value Carbon Removal Model

 

CREW uses strategically sourced alkaline minerals such as calcium carbonate to optimise key conditions including pH and alkalinity within the wastewater treatment process. The optimisation delivers better biological performance for operators while simultaneously locking away carbon dioxide and superpollutant emissions in a permanent, measurable form. The dual-value proposition combines operational improvements for utility customers with verified carbon removal credits sold to corporate buyers, creating two complementary revenue streams from a single technology deployment.

CREW has delivered verified carbon removal credits to corporations under long-term agreements with major buyers including JP Morgan, Google, Autodesk and Stripe through the Frontier coalition. Tom Ferguson, Partner at Burnt Island Ventures, said the precise measurement of permanent carbon removal is highly differentiated in the crediting market and empowers buyers to know exactly what they are paying for. As corporate buyers increasingly scrutinise the integrity of carbon removal credits, engineered solutions with robust measurement frameworks are commanding premium pricing relative to nature-based alternatives with weaker quantification methodologies.

 

Commercial Traction and Recent Milestones

 

Since launching commercial operations in 2024, CREW has deployed its technology at nearly 10 wastewater treatment facilities across the United States and Europe, including leading utilities such as Hampton Roads Sanitation District. The company has captured more than 2,000 tonnes of carbon dioxide faster and more cost-effectively than other carbon removal credit suppliers and has secured over $33 million in carbon removal offtake agreements. One utility customer is considering deferring $350 million in planned capital upgrades as a result of CREW's performance improvements, illustrating the magnitude of capital expenditure that the technology can avoid.

The company recently won a $2.3 million award from the Colorado Energy Office as part of the state's Clean Air Program, providing additional non-dilutive support. CREW has also developed proprietary measurement, reporting and verification capabilities that enable high-confidence carbon removal quantification, alongside an emerging analytics platform designed to deliver actionable operational insights for wastewater treatment facilities. The combination of physical deployments, MRV credibility and digital tools strengthens the company's competitive moat in both the water infrastructure and carbon removal markets.

Outlook for Engineered Carbon Removal in Water Infrastructure

 

The CREW funding reflects growing investor interest in engineered carbon removal technologies that leverage existing industrial infrastructure rather than requiring purpose-built facilities. Andrew Hinkly, Managing Partner at AP Ventures, said the company's pragmatic approach to delivering low-cost carbon dioxide removal positions it well for accelerated scaling. The combination of demand from utilities seeking operational efficiency and corporate buyers seeking high-quality removal credits creates a structurally attractive business model that aligns environmental outcomes with commercial returns.

Whether CREW can scale to category-defining leadership in the water and climate technology sectors will depend on continued utility adoption, expansion of offtake agreements and sustained execution against its operational and carbon removal performance metrics. The company is focused on adding talent across wastewater process, technology, supply chain and business development functions as it expands operations through 2026. Sustained progress would establish CREW as a leading example of how technologies can deliver simultaneous operational, environmental and commercial value within mature industrial sectors.
