Although BTG is an integrated Consultant and R&D firm, and not a supplier, BTG has facilitated the implementation of more than 15 spin-off companies including subsidiaries, and more than 55 bio-energy systems and factories worldwide. Our involvement has occurred in many different ways: as owner, contractor engineering firm, commissioning, project manager, project advisor, and technical assistance. Technologies covered are combustion, gasification, carbonization, flash pyrolysis, densification and anaerobic digestion. The scale covered is typically small to medium scale. Each project and company has its own characteristics and has been designed such that it complies with the needs of the client. BTG also covers performance monitoring and non-technical areas such as permits application, environmental legislation, and health & safety issues. Our aim is to demonstrate that various bio-energy concepts are feasible. If necessary, BTG is willing to invest or co-invest in promising concepts, provided a good partnership can be established and some basic requirements are met.

Examples of installed systems managed or supported by BTG include:
Wood and straw-fired combustion systems for industrial or district heating, substituting brown-coal fired units in Central and Eastern European countries ;
Briquette and/or charcoal production and biofuel trading facilities in China, Estonia and Ghana;
Anaerobic digestion units for coffee industry waste water treatment, municipal sewage plants and animal farms in the Netherlands, Belgium, Costa Rica, Hungary, Moldova and Ukraine.
