Testing and evaluating the quality of solid fuels, biofuels or secondary fuels are extremely important for the development of the industry. This applies both to their production, and to matching to different technologies. Thanks to modern scientific-research facilities, the laboratories of the Central Mining Institute have a comprehensive offer in this area, containing also the consulting and training services.
