Key Takeaways
- CarbonZero.Eco has completed its first commercial biochar production facility in Colusa County, California.
- The company signed a landmark carbon credit purchase agreement with global carbon removal leader Climeworks.
- Partnerships with almond farmers could mitigate up to 1.5 million tons of CO₂ emissions from agricultural waste.
- Biochar produced at the new facility will support soil health, water retention, and long-term regenerative agriculture in California’s Central Valley.
- CarbonZero.Eco aims to scale carbon-negative agriculture while generating new revenue opportunities for farmers.
CarbonZero.Eco Completes First Commercial Biochar Production Facility
CarbonZero.Eco, a climate technology startup focused on regenerative agriculture and carbon removal, has announced the completion of its first commercial biochar plant in Colusa County, California. Founded by 17-year-old CEO Harper Moss, the Silicon Valley–based company emerged from stealth last year with venture backing from senior leaders at major technology companies, including Google, Meta, and Amazon.
Since launch, CarbonZero.Eco has formed partnerships with more than a hundred almond farms in Colusa and Yolo Counties. Through these collaborations, the company anticipates mitigating up to 1.5 million tons of CO₂ from agricultural waste that would otherwise decompose and release emissions.
CarbonZero.Eco Highlights Biochar’s Role in Agriculture and Carbon Removal
Agricultural waste totals more than 1.5 billion tons annually worldwide, with traditional disposal approaches such as burning and landfilling contributing to an estimated 3% of global greenhouse gas emissions. CarbonZero.Eco converts almond shells into biochar, a stable carbon form that prevents CO₂ release for thousands of years while improving soil structure, nutrient cycling, and crop yields.
The company plans to transform up to 1.5 million tons of almond shells—typically decomposed within two years—into high-quality biochar used directly by partner farms.
Opens Central Valley Production Site to Support Regenerative Farming
The new Colusa County facility is adjacent to existing almond shell stockpiles, eliminating feedstock transport and reducing operational emissions. The resulting biochar will be blended into compost and applied to fields to support water retention, soil fertility, and long-term productivity.
California’s Central Valley faces significant groundwater depletion, with some areas sinking up to a foot annually. According to CarbonZero.Eco, biochar-amended soils can retain 20% more water, a threshold the company says is required to reduce strain on aquifers.
“This facility represents a major step toward making carbon-negative agriculture both practical and profitable,” said Harper Moss, Founder and CEO of CarbonZero.Eco. “By placing our first plant directly where agricultural waste is generated, we’re creating a closed-loop system that benefits farmers, the environment, and the climate. Our mission is to empower American farmers to enhance soil health, improve crop yields, and unlock new revenue streams—while removing atmospheric CO₂ at scale through next-generation biochar production.”
CarbonZero.Eco Announces Major Carbon Credit Agreement With Climeworks
CarbonZero.Eco has also signed a commercial agreement with Climeworks, a global leader in high-quality carbon removal solutions. Climeworks provides long-duration carbon removal services for companies seeking to meet net-zero targets, manage climate risk, and generate durable climate impact.
The agreement marks CarbonZero.Eco’s first major commercial carbon credit sale, positioning the company within the growing market for verifiable carbon removal technologies.
With its first facility operational and commercial partnerships expanding, CarbonZero.Eco plans to advance scalable biochar solutions that support climate mitigation and regenerative agriculture across the United States.
