The Carbon Curve What's on the horizon for Eion and enhanced rock weathering
Episode 35 is with Anastasia Pavlovic, CEO of Eion and Elliot Chang, Co-founder and CSO of Eion.
Today Na’im speaks with Anastasia Pavlovic, CEO of Eion and Elliot Chang, CSO of Eion. Enhanced rock weathering (ERW) is an area of carbon removal that I’ve been really intrigued by. When I think about ERW, I think about high potential for scale, benefits to farmers, and potentially challenging MRV.
So 35 episodes into this podcast, I’m finally doing an episode on ERW. Today I’ll be speaking with Eion’s co-founder, alongside a newly minted CEO, to educate me about what has evolved in the ERW space over the last few years and what the future has in store for this promising but still nascent carbon removal technology.
About Anastasia Pavlovic
Anastasia Pavlovic is the CEO of Eion, which she joined in December 2023 bringing deep expertise in global operations and software with a passion for driving global change through local impact. Before joining Eion, Pavlovic led operations, commercialization, and growth for the Agoro Carbon Alliance, which works with farmers to sequester carbon in soil. Prior to the Alliance, Pavlovic commercialized software solutions in the US and Canada for Yara's Digital Farming organization. She has worked for venture-backed software companies scaling agtech and security products around the world. From West Virginia, Pavlovic holds dual B.S. degrees in Electrical Engineering and Systems Engineering.
About Elliot Chang
Elliot Chang is Co-Founder and Chief Science Officer at Eion. With over ten years of research experience in ion interactions with abiotic and biotic surfaces found in both subsurface terrestrial and marine systems, Elliot focuses on the research and development of technology at Eion. Elliot provides a unique perspective on technology and innovation through his work in academia, national laboratories, and industry-based companies. Elliot has completed postdoctoral research positions at Lawrence Berkeley National Laboratory, where he studied the physio-chemical properties of swelling clays in soils, and at Lawrence Livermore National Laboratory, where he developed new computational modelling approaches for radionuclide and metal transport in soils and nuclear waste repositories. He received his Ph.D. at UC Berkeley in Environmental Science, Policy, and Management, studying rare earth element interactions with bacteria in engineered bioreactor and natural soil systems. He received his Bachelor of Science in Environmental Engineering at Princeton University with a certificate in Sustainable Energy. Elliot is a member of the American Geophysical Union, American Chemical Society, and Sigma Xi Honor Society.
About Eion
Eion is a carbon removal company responsibly scaling enhanced rock weathering (ERW) on agricultural lands. It holds an industry-first patent for directly measuring the carbon removed by mineral weathering in soils using immobile trace elements. Combining scientific rigor with agricultural know-how, Eion fits into routine farming practices to unlock scale without compromising safety and rigor. That includes using olivine, a naturally abundant mineral that balances soil pH while efficiently absorbing carbon dioxide, and relying on routine soil samples and standard equipment to measure carbon removal and monitor soil conditions. By working with the agricultural system, Eion is on track to deliver 10 million tons of permanent carbon removal annually starting in 2030 while creating stable jobs in rural communities.
In this episode, Na’im, Anna, and Elliot discuss:
* Eion’s beginning and journey thus far;
* Anna’s new role as the CEO and her experience getting into CDR from a background in agtech;
* Eion’s approach to enhanced rock weathering
* Eion’s ‘direct measurement approach’ to MRV;
* The different minerals used in ERW and the advantage of using olivine for Eion;
* The scalability and potential of ERW in reaching the scale required;
* The constraints in scaling ERW;
* Eion’s partnership with its feedstock partner, Sibelco;
* The significance of Eion’s recent delivery of carbon removal to Stripe;
* Policy supports needed going forward for ERW;
* Anna’s mandate and the company’s key priorities for 2024;
