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 CarboFlow technology produces 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.

By 2030, we're on track to deliver...

Turn problem waste into a
weapon to fight climate change

Pyrolysis takes waste biomass and produces biochar and green energy, all the while removing carbon from the atmosphere.

It transforms waste from a cost to a profit, and from a problem to an environmental solution.

The biochar produced is an excellent soil enhancer and promotes regenerative agriculture. Excess heat energy produced from the process is 100% renewable and can reduce your energy costs. The carbon removal credits can generate income or offset your own emissions.

It's a win-win for your business and the planet.

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.
