Advancing ERW Science
We are a science-driven company.
That means every decision we make aims to improve our understanding of ERW.
Our ERW project in Germany is a production-scale laboratory for testing methods and technologies that can transfer to business cases around the world.

The science is simple. But here is the secret:
While the underlying reaction of ERW is well-understood, the trick is to speed up natural weathering as much as possible. By enhancing the rock surface area and optimizing distribution, we accelerate what would take millenia to happen and turn farmland into carbon-capturing ecosystems.
Measuring carbon removal rigorously and economically is still the biggest challenge.
So we developed a scalable and accurate solution:
Ion Exchange Resins
There are some big scientific questions left to solve in ERW, and ZeroEx is in it for the long haul.
From bicarbonate lag time to secondary clay format ion, there isn’t much we aren’t interested in. If you are a researcher working on ERW, we want to hear from you!
