Unlocking Asia's climate - positive potential
South East Asia is perfectly placed to lead the world in large-scale climate solutions, through the abundance of biomass and thriving agricultural and industrial sectors.
Onnu Bioflow exists to develop this market, and address unique local challenges, and deliver benefits to people and businesses in the region, and the planet as a whole.

Our story
Originating in the UK, Onnu built a leading specialism in biomass pyrolysis, to the build the biochar carbon removals industry in a way that was commercially beneficial.


Launching our first project in SE Asia, we joined our pyrolysis expertise with torrefaction and AD to widen the climate positive products generated from abundant waste biomass.
With our own supply and others, we launched Onnu Bioflow to trade in biomass- derived products and provide reliable, consistent supply chains to large-scale customers.
