Company Description
We are a pre-seed stage startup working to convert mine pit lakes into massive carbon sinks. After closure, open pit mines will passively fill with groundwater, creating a pit lake. Water quality is often poor, and without treatment these systems pose a threat to communities and wildlife. More recently-formed pit lakes do get treated in places where environmental laws are enforced, but at a cost and with few beneficial end uses. We use these degraded water bodies to capture up to tens of millions of tons of CO2 per site—as beneficial an end use as there’s ever been. With thousands of sites globally the potential impact is huge.
Our process is a hybrid of two emerging carbon dioxide removal techniques, enhanced rock weathering and ocean alkalinity enhancement, maintaining the best aspects of both while solving their challenges. The result is inexpensive, measurable, permanent, and scalable carbon storage.
