BTG Biomass Technology Group BV is a SME specialised in the conversion of biomass into biofuels and bioenergy. BTG is active in the field of studies & consulting, project & business development, applied R&D, technology development and engineering. BTG is one of the pioneers in biomass pyrolysis and started the fast pyrolysis developments at the beginning of the nineties with a new reactor concept in which no inert gases were required to enable rapid mixing of biomass and hot bed material. This concept was the result of research done at the University of Twente where rapid mixing was achieved by mechanical mixing inside a rotating cone reactor. Over the years, BTG further improved and optimised the concept. BTG`s modified rotating cone technology has resulted in several patents.

In 1998, BTG built a pyrolysis pilot plant on laboratory scale (80-250 kg/hr). A smaller version of 1-5 kg/hr dry biomass input was developed several years later (in 2004) to be able to perform smaller tests with more challenging feedstocks. BTG has successfully tested over 45 different kinds of feedstock over the years, ranging from relatively simple feedstocks like wood to difficult feedstocks like sludge or EFB. In 2005 BTG started the demonstration of the pyrolysis technology on Empty Fruit Bunch (EFB) in Malaysia on a scale of 2 t/hr. The successful construction of the first production unit was built for and operated by a client in Malaysia.

Through its daughter company BTG BioLiquids BV, established in 2008, BTG is boosting the worldwide uptake and commercial implementation of its flash pyrolysis technology.
