CREW Carbon is thrilled to announce that Dr. Chris Reinhard, a leading expert in carbon dioxide removal and earth system modeling renowned for his pioneering work in enhanced weathering, has joined the company as Senior Scientist. A co-founder of Lithos Carbon and Professor at Georgia Tech, Chris brings decades of experience in biogeochemical cycles, carbon dioxide removal, and weathering dynamics to CREW’s mission to deliver durable, value-added carbon removal.

Chris is at the forefront of research on alkalinity-based carbon removal pathways and is an expert on enhanced weathering measurement, reporting, and verification (MRV). Having authored seminal papers and developed pioneering models that are essential for enabling carbon dioxide removal with enhanced weathering, his research is critical for accurately tracking the long-term fate of captured CO₂ and thus measurable, durable carbon dioxide removal. 

At CREW, Chris will provide strategic technical guidance on our carbon removal system approach, environmental monitoring, and earth system modeling, as well as our model-based MRV strategy, helping to ensure the scientific rigor and impact of CREW’s enhanced weathering and wastewater alkalinity enhancement deployments. Chris will be joining CREW’s Scientific Advisory Board, which includes Professor Peter Ramyond, co-director of the Yale Center for Natural Carbon Capture.

Dr. Reinhard is an Associate Professor in the School of Earth and Atmospheric Sciences and the Georgia Power Chair at Georgia Tech. 

“We’re honored to welcome Chris to the CREW team,” said Joachim Katchinoff, CREW Co-Founder & CEO. “His depth of expertise in biogeochemistry, Earth systems modeling, and alkalinity-based carbon removal  will be invaluable as we scale our solutions and ensure they are grounded in the best available science.”

“I’m excited to support CREW Carbon’s mission to accelerate scientifically rigorous carbon removal,” said Dr. Chris Reinhard. “CREW’s approach to wastewater alkalinity enhancement is deeply rooted in Earth system thinking, and I look forward to contributing to the team’s efforts to build climate solutions that are both effective and responsible.”

About CREW Carbon

CREW Carbon enhances municipal and industrial wastewater treatment to solve the planet’s CO₂ problem. Our engineered enhanced weathering technology doses wastewater with minerals like limestone, delivering efficient, cost-effective alkalinity treatment while permanently removing CO₂. By maximizing existing infrastructure, our closed-system approach offers scalable, affordable, and measurable carbon dioxide removal. Wastewater facilities get better treatment at lower cost; carbon buyers get high-quality, durable credits, and the planet gets fewer greenhouse gasses. CREW Carbon is the win-win the world needs.

CREW Carbon is pleased to announce that we’ve delivered our first verified Wastewater Alkalinity Enhancement (WAE) carbon dioxide removal (CDR) credits to Frontier buyers. These initial 104.4 credits, verified by Isometric, mark the first delivery under our 6 year, $32.1 million offtake agreement with Frontier buyers including Frontier founders Stripe, Google, Shopify, and members Autodesk, H&M Group, Workday, Salesforce, Watershed, and JPMorgan Chase.

The credits were generated from CREW’s flagship, multi-kiloton project at the East Shore Water Pollution Abatement Facility operated by the Greater New Haven Water Pollution Control Authority (GNHWPCA), and represent a significant milestone for scaling carbon removal and demonstrating WAE’s potential as a carbon removal pathway. 

This project will soon be one of the largest operating carbon removal projects on the East Coast of the U.S., integrating into a facility which processes 40 million gallons of wastewater per day. Located on the shore of the New Haven Harbor, the GNHWPCA oversees an extensive sewer system spanning over 555 miles of pipeline and 30 pump stations, which is all in service of keeping the local community and environment safe, including the Long Island Sound.

From our Co-Founder and CEO, Dr. Joachim Katchinoff, “Maximizing existing infrastructure and using proven science, CREW’s engineered enhanced weathering approach offers a cost-effective, highly measurable and globally scalable approach to durable carbon removal. In addition to providing an essential service to our communities, wastewater treatment plants are powerful places to remove CO₂. By integrating directly into existing infrastructure, CREW’s WAE technology transforms everyday facilities—like the East Shore Facility—into climate assets, delivering durable, measurable carbon removal while improving treatment efficiency, lowering OpEx costs, and helping operators protect the local environment. This milestone proves that carbon removal doesn’t need to wait – it’s already happening.”
