What They Do

CQuestr8 have designed an industrial mineralisation reactor that dramatically accelerates a natural process: the weathering of abundant alkaline minerals in the presence of CO₂. This has the double benefit of locking away CO₂ permanently and creates a useful cementitious material that can help displace emissions intensive ingredients in concrete.

Why It Matters

As carbon removal and carbon capture scales, the world is going to need many solutions to storing CO₂ durably. We expect those that are location independent, produce useful, saleable products and don’t require rarified feedstocks will thrive. CQuestr8’s solution is particularly attractive thanks to their engineering innovations which ensure a near-complete reaction while minimising energy consumption.
