Bio2oil | Turning waste into a carbon neutral oil

Our technology

Our technology, Bio2Oil is well suited for multiple applications, such as:
wastewater treatment, plastics, manure, and many more.

We offer a unique implementation of our bio2oil technology (Hydrothermal liquefaction) the HTL technology that is ready to handle the decentral nature of biomass. Research has shown that HTL is one of the most energy-efficient solutions for handling wet biomass streams.



  • To reduce capital expenditure cost compared to traditional technologies.
  • To develop cost-efficient standard units, which can easily be upscaled.
  • To develop and market processes that are in themselves profitable.

The produced biocrude can be used in traditional flows for crude oil and has the potential to be upgraded to jet-fuel, maritime fuel, diesel, and bunker oil. This way, it paves a new path for the transportation industry towards independence from fossil fuels.
