BTG-RTD develops technologies for the (thermochemical) conversion of biomass and residues into a wide range of useful products like heat, power, biofuels, chemicals and materials. These technologies are in different stages of development ranging from R&D activities to commercial application. The implementation and commercialisation of BTG’s fast pyrolysis technology has been transferred to the daugther company BTG Bioliquids BV.

Fast pyrolysis

Fast pyrolysis is a process in which organic materials are rapidly heated to 450 - 600 °C in the absence of air.

Supercritical water reforming

By treatment of biomass in supercritical water organics are converted into fuel gases and are easily separated from the water phase by cooling to ambient temperature.


In BTG’s two-stage gasification process, biomass and residues are converted  in an organic vapour and subsequently into a clean fuel gas.


Torrefaction is a thermal process to convert biomass into a coal-like material, which has better fuel characteristics than the original biomass.

Energy from pyrolysis oil

Pyrolysis oil can be used in several applications to produce heat, electricity and cooling.


Two different routes are currently considered to produce biofuels from pyrolysis oil: hydrodeoxygenation (HDO) and syngas production.

Bio-materials & chemicals

Pyrolysis oil from biomass & residues contains a large amount of different components and can be the basis for a huge number of new products and chemicals.

Liquid phase processing

Liquid Phase Processing (LPP) or Liquid Phase Reforming (LPR) is the treatment of organic material in the liquid phase.
