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.
