Biochar Carbon Capture in the United States
Utilising advanced pyrolysis technology to sequester carbon and improve soil health, this project converts agricultural and wood waste into biochar, which acts as a long-term carbon sink.
This innovative project in the United States employs 100% biomass from wood and agricultural waste to produce biochar, a high-carbon material that sequesters atmospheric CO₂. By creating a permanent carbon sink and improving soil quality, it addresses key environmental challenges.
Location: United States of America
Project Type: Forestry & Land Use
Project impacts
Climate & environment
- Atmospheric Carbon Sequestration: Locks carbon into the soil for hundreds of years
- High-Carbon Content: Biochar contains 81% – 84% carbon by dry weight
Social & economic
- Sustainable Feedstock: 100% renewable biomass sourced from agricultural and manufactured wood waste
- Soil Health Benefits: Enhances water retention, nutrient availability, and soil fertility
This project contributes to multiple UN Sustainable Development Goals, delivering measurable environmental and social outcomes.
Project details
This project, based in the United States, transforms agricultural and wood waste into high-carbon biochar using biomass pyrolysis. This fossil fuel-free process locks carbon into a stable form, preventing its release into the atmosphere. With carbon content between 81% and 84%, this biochar is among the most carbon-rich materials currently available.
About the project
Since the industrial revolution, human activity has disrupted the natural carbon cycle, leading to excessive carbon emissions. While reducing emissions is critical, capturing and storing atmospheric carbon is equally essential.
Biochar is a charcoal-like material produced through biomass pyrolysis, where organic residues are burned at high temperatures in the absence of oxygen. Its recalcitrant nature makes it resistant to decomposition, ensuring long-term carbon storage in the soil.
This project utilises 100% biomass, derived from wood and agricultural waste, to produce biochar without the use of fossil fuels. Beyond its role in carbon sequestration, the biochar enriches soil health by improving water retention and nutrient-holding capacity. It also contributes to landfill emissions management and soil regeneration.
