# Joachim Katchinoff

> Joachim Katchinoff is a Yale-trained biogeochemist who co-founded CREW Carbon to turn ordinary wastewater treatment plants into permanent carbon-removal machines. By dosing treatment tanks with crushed alkaline minerals, CREW converts the CO2 that microbes naturally belch into stable bicarbonate, while cutting chemical costs for utilities. The company became the first in the world to issue certified Wastewater Alkalinity Enhancement carbon credits and raised a $25M Series A in 2026 to scale across the US and Europe.
