CREW Carbon
CREW Carbon is a Yale-spinout water and climate technology company based in Hamden, Connecticut. It retrofits municipal and industrial wastewater treatment plants with a closed-system enhanced-weathering process: dosing alkaline minerals into wastewater to convert dissolved CO2 into stable bicarbonate. The approach lowers operating costs and improves treatment performance for utilities while permanently and measurably removing atmospheric carbon, which it sells to corporate buyers as durable carbon removal credits.
