Biochar carbon removal.
For climate action today.
Our pyrolysis plants unlock the vast potential of underutilized biomass using
Onnu's proprietary CarboFlow technology. Good for the planet, people and profits.
Biochar
Our Green Hubs produce consistent, high quality biochar, at scale.
Carbon Removal
Our process locks away atmospheric carbon, generating valubale carbon credits.
Green Energy
We use green energy from the pyrolysis process for onsite applications or sale.
Onnu Green Hubs
We develop BCR projects in locations where we can deliver maximum environmental benefits:
- Close to good quality feedstock, currently with low value or causing environmental harm.
- Using all our green energy to displace carbon intensive generation.
- At sites where we can scale up to >20,000 tCO2e annual removal.
We build our own projects, or work with partners with suitable sites or feedstock to share the benefits.

Business model
Our Green Hub carbonization plants all operate on a simple yet highly effective business model:
Inputs
Pyrolysis
CarboFlow
Feedstock is thermally decomposed into biochar and syngas, which is combusted for energy to maintain the process and power any required drying process.

Owner-operated pyrolysis plants powered by CarboFlow
Onnu's production sites use our proprietary pyrolysis technology, CarboFlow - engineered with years of first-hand experience of what is required to make pyrolysis projects truly viable.
The ability to work with a variety of feedstocks, the time to manufacture, and the cost of production are all challenges we addressed in CarboFlow's design. Through the introduction of our own technology we can accelerate the rollout of projects that bring the biomass pyrolysis industry closer to its full potential.
CarboFlow is a high-performance, end-to-end pyrolysis machine that delivers both environmental and financial sustainability.
Sustainable development goals
Pyrolysis operations contribute to 8 of the 17 sustainable development goals (SDGs).
