Paydirt: Rock Dust, Rice, and a Smallholder’s Reward

Mati Carbon's Shantanu Agarwhal takes a selfie with rice farmers During the 2024 monsoon season, carbon removal company Mati Carbon spread close to 40,000 tonnes of crushed basalt across more than 8,000 rice paddies in central India. The rock was quarry waste from a short drive away. By harvest, the treated farms had something to show in two currencies at once: more rice, and removed carbon. Mati Carbon, based in Houston, won the $50 million XPRIZE Carbon Removal grand prize in April 2025 for this practice. A new preprint, Jordan et al. (2025), reports the first commercial-scale evidence that enhanced rock weathering (ERW) can raise smallholder ...

Can Rock Dust Soak Up Carbon Emissions? A Giant Experiment Is Set to Find Out

When Lithos Carbon co-founder Mary Yap saw piles of basalt dust at a quarry, she saw more than industrial waste. “When we saw these enormous mountains of basalt dust, we realized this could become a truly meaningful solution.”

CDI’s New 48 Hour Shaker Test Speeds Up Verification of Enhanced Rock Weathering

Dirk Paessler, Founder and CEO of Carbon Drawdown Initiative There has been a breakthrough by the Carbon Drawdown Initiative (CDI): they have discovered how to speed up the testing of Enhanced Rock Weathering (ERW) using the 48-Hour Shaker test, a rapid verification of weathering that will advance Carbon Dioxide Removal research and aid in the development of standardization within the field. This research is done through CDI’s Project Carbdown. Project Carbdown is a project implemented by the Carbon Drawdown Initiative in partnership with scientists across Europe, including 20 scientists from 6 universities. Project Carbdown is a form of ...

The Kingston Wollastonite Rebate

Wollastonite, when crushed into rock dust and incorporated into the soil through the process of enhanced rock weathering (ERW), is greatly beneficial.

Silicon to Silicate: Understanding the InPlanet-Microsoft Deal

On December 17, 2025, InPlanet, a trailblazing ClimateTech Carbon Dioxide Removal (CDR) company, publicly announced that they signed an agreement with Microsoft, the multinational tech conglomerate, to provide durable carbon removal and regenerative agriculture benefits in Brazil. They plan to remove more than 28,500 tonnes of carbon dioxide between 2026 and 2028.  Who is InPlanet? InPlanet’s Team. Image Credit: InPlanet Founded in 2022 and based in Germany and Brazil, InPlanet is an AgTech Company pioneering Enhanced Rock Weathering (ERW) as a scientifically rigorous pathway for durable CDR and regenerative agriculture. They ...

The Future of Carbon Removal is Enhanced Rock Weathering: Introducing the Everest Pulsar

When developing climate change solutions, one may look to Mother Nature for inspiration.

Ukraine’s Path to Soil Remineralization

In a field in Eastern Ukraine, where heavy military equipment was moving just a few months ago, agronomists are now attempting to restore degraded soils by spreading finely ground basalt across the soil. What looks like an ordinary farming operation is, in fact, an attempt to build an evidence pipeline:mineral → field → measurement → standardization. This is where agronomic effects can already be observed on the ground, though the climate layer still requires formal Monitoring, Reporting, and Verification (MRV) frameworks, that is, a transparent system for monitoring, reporting, and independently verifying carbon dioxide removal. This is ...

The Royal Society Meeting: Enhanced weathering with agriculture for atmospheric carbon dioxide removal

Event title: Enhanced weathering with agriculture for atmospheric carbon dioxide removal Date: November 17 - 18, 2025 Location: The Royal Society, 6-9 Carlton House Terrace, London SW1Y 5AG United Kingdom Cost: Free Host organization: The Royal Society Description: This meeting will discuss advances and uncertainties in terrestrial enhanced weathering, a key carbon dioxide removal strategy for climate change mitigation. Recent discoveries and R&D investment are accelerating the prospect of large-scale EW implementation, but uncertainties remain. The goal of this meeting is to provide a much-needed balanced discussion on the ...

5th Brazilian Congress of Remineralizers Conference

Event: V Congresso Brasileiro de Rochagem Date: July 8 – 11, 2025 Location: Piracicaba, Brazil Host organization: Luiz de Queiroz College of Agriculture, University of Sao Paulo Seminar description: After 15 years of the realization of the 1st Brazilian Congress of Remineralizers, the theme of remineralization gained prominence in Brazil and in the world. Soil remineralizers (REM), are derived from silicate rocks and when properly used, improve soil conditions since they behave as multifunctional inputs (nutrient source, acid neutralization, colloid neoformation). The regulation of this input (Law 12,890 of 2013 and Normative ...
