Scientific Papers
At Andes, we believe that true impact and scalability are built on a foundation of rigorous science and collaboration. Our approach to microbial carbon dioxide mineralization (MCM) for carbon dioxide removal (CDR) is backed by years of research, from controlled laboratory settings to large-scale field trials.
We are committed to scientific rigor and transparency, ensuring that our carbon removal technology is effective, permanent, and beneficial for soil health.
Below, you will find our latest peer-reviewed findings that validate our technology and methodology for carbon dioxide removal.
From silicates to soil carbonates:
Tracing the cation budget of microbially accelerated weathering
This manuscript has been submitted for peer review.
This study uses sequential selective soil extractions to trace the fate of base cations released during microbially accelerated silicate weathering. This work validates Andes' CDR approach and confirms that soil inorganic carbon (SIC) measurements are a robust and necessary method for verifying carbon removal.
The preprint is available through the CDRXIV preprint repository.
Harnessing Microbes for Scalable Carbon Dioxide Removal in Agricultural Soils
Published in Global Change Biology
Led by Andes’ CTO and Co-Founder, Dr. Tania Timmermann, this foundational paper validates our core carbon dioxide removal (CDR) technology. Through a comprehensive suite of in vitro assays, mesocosm studies, and field trials, we demonstrate how Andes’ beneficial microorganisms accelerate the weathering of native soil silicates. The result is measurable, permanent carbon dioxide removal that integrates seamlessly into existing agricultural systems.

Synergistic Effects of an Andes Microbial Amendment and Crushed Basalt
Published in Global Change Biology
This study explores the powerful synergy between biology and geology. It investigates how co-applying Andes’ proprietary microbial strain (MP1) with crushed basalt significantly enhances carbonate alkalinity while preserving soil organic carbon. Conducted in a soybean mesocosm system, this research is a critical step toward developing scalable, hybrid Carbon Dioxide Removal (CDR) strategies that integrate soil microbiology with enhanced rock weathering.

Precise measurement of soil inorganic carbon (SIC) and dissolved inorganic carbon (DIC)
Published in PLOS One
Accurate measurement is the bedrock of trust in carbon markets. Led by Dr. Chris Yip and Dr. Phil Weyman, this work introduces a novel, high-throughput gas chromatography technique for quantifying inorganic carbon. This method delivers exceptional precision for both solid soil and pore water samples, setting a new standard for measurement, reporting, and verification (MRV) in soil carbon projects.

Our published work is just the beginning. Andes is building a collaborative ecosystem to scale microbial carbon dioxide mineralization globally. Whether you are a researcher, an organization looking to support high-integrity carbon dioxide removal science, or an industry innovator, we want to hear from you. Let’s accelerate the path to scale carbon dioxide removal together.
