Welcome to the EMPYRO project website!

The EMPYRO project - in full: Polygeneration through pyrolysis: Simultaneous production of oil, process steam, electricity and organic acids - started in December 2009. The main aim of the project is to build and demonstrate a 25 MWth polygeneration pyrolysis plant to produce electricity, process steam and fuel oil from woody biomass. The produced fuel oil can be used on-site, sold to a regional customer or exported. If you are interested in purchasing Pyrolysis oil from the plant to be constructed, please contact BTG Bioliquids BV at office@btg-btl.com. The project also aims at developing and demonstrating the recovery of acetic acid from the aqueous organic acid solution that is produced as part of the pyrolysis oil production process.


The EU Empyro project was successfully concluded in 2015. The main result of the project - the Empyro pyrolysis plant - is operational and produces pyrolysis oil on a daily basis. Further information on the implentation of the technology can be found at btg-btl.com/en

8 February 2014 - Construction of the first pyrolysis plant (biomass-to-liquid) has started

Empyro BV announces that the construction of its pyrolysis oil production plant has started at the AkzoNobel site in Hengelo (The Netherlands). By the end of this year construction will have been completed. The production capacity will then be gradually increased to its maximum of over 20 million litres of pyrolysis oil per year. This amount of renewable oil will replace 12 million cubic meters of natural gas, the equivalent annual consumption of 8,000 Dutch households, which saves up to 20,000 tonnes of CO2 emissions per year. Additionally, the project creates approximately 100 person-years of work in Overijssel. The full press release is available here (English) or here (Dutch).

The EMPYRO project is coordinated by BTG Biomass Technology Group B.V. (the Netherlands). It will be carried out by a consortium of nine complementary partners, including technology providers, developers and manufacturers, a biomass supplier, an industrial end-user and a CFD modeling expert. Coordination tasks are split between technical issues and administrative issues.

The EMPYRO project is financially supported by the 7th Framework Programme of the European Commission (Grant number 239357). It applied to the call for proposals FP7-ENERGY-2008-TREN-1; topic: High efficiency poly-generation – renewable energies for application in industry.
