The carbon loop,
finally closed.
Zero transforms unavoidable organic waste into permanent carbon removals and clean industrial fuel - making decarbonization economically inevitable.
Heavy industry emits 20 - 30 GT of CO2 every year.
T H E P R O B L E M
Coal, oil, gas, steel, and cement alone account for the majority of global emissions. Organic waste from crops, food, and forestry adds billions more tons, carbon that was already captured from the atmosphere, then biodegraded and returned to the atmosphere.

Drop-in biochar replaces coal in steel, cement, power generation - no retrofits required.
MRV-verified permanent carbon storage. Stable for 1000+ years.
We handle crop, food, forestry, and municipal waste - turning disposal costs into carbon value.
Zero’s proprietary process bypasses the high activation energy barrier that makes traditional carbonization expensive. Lower energy input, fraction of the cost. The same result: permanent carbon.
Cleaner must be cheaper.

Zero began as a Stanford-born idea and grew out of deep research and early development on campus. Today, our team brings together expertise from Stanford, Caltech, UC Berkeley, and beyond—combining science, engineering, and climate strategy to scale biochar globally.
