Biochar carbon removal.
For climate action today.

Pyrolysis with ambition

CarboFlow uses an upright design where airflow keeps the lower carbonization chamber oxygen-free while syngas is combusted above, radiating heat downwards.

As an experienced project developer, Onnu understands that pyrolysis operations need to stack up financially. By increasing throughput, harnessing advanced automation and capturing green energy, plants using our technology can run efficiently and reliably which all leads to a financially sustainable operation.

We have streamlined the design of the PyroUnity to ensure simplicity and efficiency at every stage. From installation to daily operation and routine maintenance, our systems are engineered for ease of use. Modular components and standardised connections allow for quick setup, while an intuitive control interface makes operation straightforward, even for non-specialist operators.

The accessible layout of critical parts ensures that servicing and maintenance can be carried out quickly and safely, minimising downtime and maximising productivity. By combining robust engineering with user-friendly design, we deliver machines that are both highly efficient and practical to run.

Achieving carbon removal through pyrolysis

By creating biochar, the carbonization plants we build for our customers remove greenhouse gases (GHG) from the atmosphere. They therefore qualify for carbon credits which are issued by an independent registry.

These carbon credits can then be sold on the open market or retired by the plant owner to reduce their reportable emissions.

Carbon credits are measurable, verifiable emission reductions from certified climate action projects. These projects must adhere to a rigorous set of criteria set by leading carbon offset standards like Puro, Isometric or Rainbow.
