Production sites
Our production sites are situated precisely where the feedstock is produced, and in close proximity to key transport hubs.
How do we choose a site?
Choosing a site is a crucial decision that will heavily impact the supply chain and trade of the commodity in question. When deciding on the location of a new site, we take the following factors into consideration:
Our production sites
BioCarbon Technology Asia
Pyrolysis of waste oil palm trunks (OPT) and empty fruit bunches (EFB) to produce biochar, black pellets and biogas while achieving carbon removal.
Excess heat from pyrolysis is used to dry EFB before being fed into a torrefaction machine plant that produces black pellets. A biogas plant on site captures methane from palm oil mill effluent (POME), producing biogas for electricity generation and biomethane for use as fuel in its trucks, whereas a liquefaction unit produces bio-LNG.
Location: Sabah, East Malaysia
Shipping port: Tawau
Technologies deployed: Pyrolysis
SEAD
Pyrolysis of bamboo offcuts to produce biochar, biocarbon and green energy while sequestering carbon.
Sourced from local partners like SEAD, the bamboo offcuts come from sustainable agroforestry efforts that rehabilitate degraded land and support community livelihoods. Instead of decomposing and releasing CO₂, the offcuts - rich in carbon - will be pyrolysed using Onnu’s proprietary technology. The project will sequester around 5,000 tonnes of CO₂ per year and return 50% of the biochar to local farmers, completing the circular bamboo cycle.

Technologies we're engaged in
We are proud to partner with leading innovators to build breakthrough technologies that transform biomass into high value renewable commodities like biochar, black pellets and biocarbon. By leveraging advanced processes like pyrolysis and torrefaction, we not only address the problems of disposing of organic waste but also remove carbon from the atmosphere. Our collaborative efforts focus on optimizing these cutting-edge technologies to create reliable, low-carbon solutions that drive the transition to a more sustainable, circular energy future.
Pyrolysis
Pyrolysis is the thermal decomposition of biomass in an oxygen-limited environment. This produces syngas, which can be combusted in a controlled way for renewable energy production, and biochar, a carbon-rich material that can lock carbon away for 100+ years.
The pyrolysis process begins with organic feedstock entering the feeder. This feedstock has been dried to below 20% moisture content. The feedstock enters into the reactor, where it is heated to 600+°C. Feedstock in the chamber is thermally decomposed into syngas and biochar.
The pyrolysis conditions can be altered to change the outputs of the process. This can be used to achieve project specific goals, for example maximum carbon sequestration in the biochar, or maximum syngas yield.
Carbon Activation
Activation converts carbon-based materials like biochar into a much more porous product via heating and use of gases which react with the carbon and create pores in its place. This increases the overall surface area of the material to enable the product to better trap chemicals, gases and other pollutants.
To convert biochar into activated carbon, biochar is reheated to 800-1000 °C, then steam or CO₂ is introduced to react with some of the carbon and remove part of its structure. This controlled burn-off creates many new pores on top of biochar’s existing porosity, dramatically increasing its internal surface area and enabling it to adsorb substances more efficiently for applications like water and air purification or chemical removal.
