About
Green Sequest is a Polish startup founded in 2022 and based in Nasławice that focuses on carbon sequestration through Enhanced Rock Weathering (ERW), using antigorite serpentinite to remove CO2 from the atmosphere while also providing mineral fertilizers for agriculture. The company is developing a low-cost, verifiable, scalable technology based on thermoactivation and organic salts to accelerate the natural mineralization process of serpentinite. As of 2025 the company had not raised institutional funding rounds.
