HTU® Industries originated from the collaboration between two experienced scientists, Ir. Jaap Naber and Dr. Ir. Frans Goudriaan. Together, they developed the Hydrothermal Upgrading (HTU®) technology.
We combine technological innovation with an integrated approach: from manure surpluses to high-quality products for infrastructure and mobility, without energy-intensive processes. This provides a solution that is both ecologically and economically valuable.
A sustainable future for sustainable infrastructure and clean mobility.
Ir. Jaap Naber
Founding director
Jaap studied Chemical Engineering at Delft University of Technology (TU Delft) and has many years of experience as a chemical engineer in circular technology and biofuels. As co-inventor of the HTU® process, he works at HTU® Industries on further development for applications in green asphalt and sustainable fuels.
His focus is on thermochemical processes and innovative solutions within the energy transition.
As co-founder of Biofuel B.V., Jaap Naber played a key role in the development of the HTU® process (Hydrothermal Upgrading), a technology that efficiently converts wet biomass into biocrude – a sustainable raw material for biobitumen and biofuels such as biodiesel and SAF (Sustainable Aviation Fuel). Jaap is co-inventor of several patents, including the international patent US 7,262,331* from 2007.
Within HTU® Industries, Jaap focuses on further developing the HTU technology, with the aim of using biocrude as a base for bitumen for green asphalt, and in the long term, bio methanol as a raw material for sustainable aviation fuel (SAF) and biofuel for the shipping industry.
With his in-depth knowledge of thermochemical conversion and his innovative approach, Jaap contributes to solutions that reduce CO2 emissions, break fossil dependency and strengthen the circular economy. He is determined to complete the innovations he started together with Frans Goudriaan with a powerful, energetic and green result.

Dr. Ir. Frans Goudriaan
(1941-2025) Pionier in HTU-innovatie en biobrandstoffen
Frans Goudriaan (1941-2025) studied Chemical Engineering at Delft University of Technology (TU Delft) and obtained his PhD from the University of Twente. As a leading scientist and co-inventor of the HTU® process, he laid the foundation for today's HTU® technology.
At Shell Research, Frans Goudriaan worked for many years on various chemical and catalytic processes. For eight years, he led the research into the HTU® process (Hydrothermal Upgrading), focused on the efficient conversion of biomass into high-quality biofuels.
In 1996, he co-founded Biofuel B.V. with Jaap Naber. There, he played a central role in scaling up the HTU® process with a pilot plant that processed 100 kg of biomass per hour, with the aim of producing sustainable biocrude.
Frans is co-inventor of the patent ‘Process for the production of liquid fuels from biomass (US7,262,331)’, which describes a continuous process for converting wet biomass into liquid biofuel products at high pressure and temperature. His work laid a solid foundation for thermochemical biomass conversion: with his innovative approach, Frans contributed to techniques that can process wet biomass without energy-intensive drying processes, with yields of >98%. HTU® Industries is particularly grateful to Frans for his dedication and pioneering spirit.
His legacy flows into all current efforts in the field of HTU® technology, from green asphalt to biofuels for aviation and shipping. His energy, vision and technical expertise remain guiding principles for the further development of circular energy solutions within HTU® Industries.
