Pyrolysis technology
engineered for commerical success

Our high-capacity, lower-cost pyrolysis technology delivers better returns on your investment, while making the highest quality biochar.

That means more carbon credits, more biochar, more green energy.

Affordable

CarboFlow clients' payback time is half that of other projects.

Versatile

CarboFlow is able to pyrolyze a broad range of feedstocks.

High-capacity

Throughput of up to 850 kg/hr, and easily scaled up or down.

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.

Business model

A carbonization plant can be both hugely environmentally positive, and profitable:

Inputs

Forestry waste
Waste biomass
Agricultural residue
AD digestate

Biomass

Feedstock can come from many organic sources.

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.

Outputs

Heat & electricity

Excess energy can be delivered as hot air, water or steam, and co-generation of electricity.

Biochar, biocarbon or activated carbon

Pyrolysis produces a range of valuable and climate positive products.

Carbon credits

Carbon removal credits can be sold for income, or retired to reduce your own emissions.

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.
