Our vision
We believe that biomass pyrolysis is the most reliable and scalable form of carbon removal available to us right now. Simply, our vision is to see the vast potential of BCR realised through the rollout of pyrolysis plants across the world.
The cost of pyrolysis technology has previously held back the BCR industry. However, we are now at a point where biomass pyrolysis technology can become more mainstream through a price-point that is commercially viable for more projects.
Through our lower cost CarboFlow machine and innovative shipping and install methods, we can make a real difference.
Our targets
Our CarboFlow technology delivers clean energy, while capturing carbon, manufacturing biochar and investing in local circular economies.
By 2030, we aim to have facilitated the annual delivery of:
160k tCO2e
of carbon
removed
80k t
biochar
manufactured
200 MW
of clean energy generated
across 29
operational pyrolysis sites
About Us
Onnu is a developer of biochar carbon removal projects. We develop BCR projects in locations where we can deliver maximum environmental benefits and build both our own projects, or work with partners with suitable sites/feedstock to share the benefits.
Onnu Engineering is a pyrolysis technology provider. Our CarboFlow technology delivers clean energy, captures carbon and produces biochar, creating a more circular economy.
Our design & manufacture
Onnu is committed to excellence in our manufacturing and supply chain, working with the best partners and highest quality components to ensure that our equipment is high-performing, reliable and value for money.
Lead designer - Seb Burn
Seb is a veteran of biomass pyrolysis and has worked in the industry, with multiple biochar production technologies, for 15+years. He has lead the implementation of various equipment in North and South America, Europe and Asia.
Seb has taken the practical experience of both build and operation to produce a design for CarboFlow that maximizes performance and ease of operation, while ensuring commercial viability.
Global reach
Working in close proximity to the locations of our first CarboFlow installations, the core of our manufacturing is in Malaysia, where we work with world-class manufacturing companies with specialisms in the various components we need.
We have designed CarboFlow to be flexible, allowing us to distribute work to partners in different regions of the world as our roll-outs require, ensuring quality, minimizing transportation and supporting local economies.
Quality assured
Our CarboFlow units are made from high-grade steel, and utilize best-in-class components to ensure reliability and longevity. Where components are expected to require replacement over time, they are inexpensive and accessible to minimize downtime and disruption.
CarboFlow is fully CE compliant, ensuring adherence with the latest EU health, safety and environmental protection regulations. Backed by the Declaration of Conformity and the official CE marking, it delivers proven reliability of our machinery and absolute confidence for customers.
Sustainability
Each CarboFlow unit is manufactured from responsibly sourced steel and components, with a focus on longevity and recyclability.
We prioritize local fabrication, efficient transport, and environmentally responsible suppliers to keep the machine’s embodied carbon as low as possible.

How we built CarboFlow’s intuitive HMI
Modern pyrolysis machines are powerful and often very complex pieces of engineering. Whilst we understand our machines down to the last bolt, how do we make sure an operator understands the controls, flows and intricacies? This falls on the Human Machine Interface (HMI) which is, in very simple terms, a display screen used to control the machine.
