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.

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:
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!
Collaboration with Yale University to test the performance of SIAs against several other MRV methods.
Mesocosm experiment in collaboration with Novonesis to test whether carbonic anhydrase (CA) enzyme can speed up dissolution of ERW feedstock.
Field trial conducted by Cascade Climate & Carleton College to test the performance of SIAs in comparison to conventional MRV methods.
Field trials including > 200 SIAs, testing different installation methods and depths on three research plots in the Eifel region in Germany.
Assessment of potentially toxic elements in ERW funded by the Climate Intervention Environmental Impact Fund (CIEIF).
Comparison of SIAs to alkalinity sensors in a field trial funded by the Cascade Climate ERW Field Data Partnership Grant in collaboration with Basic Dust and the University of Copenhagen.
Collaboration with Ludwig-Maximilians University (LMU) to evaluate the relationships between soil parameters and microbial community structure in rock-treated soils.
