Work in the laboratory focuses on three key areas in biomass treatment technologies: new materials processing, development of new biomass treatment and processing technologies and solid fuel standard tests. Research area is related to biomass thermal and chemical processing, including physical activation, fast and slow pyrolysis, torrefication, hydrothermal treatment, densification and extraction underpinned by detailed analytical quantitative and qualitative characterisation, mechanical testing, feasibility studies and practical tests on laboratory scale units. These approaches are used to ensure that the technologies under development are optimised, economically more promising and appropriate for manufacturing.

Biomass and its products physical, chemical  and mechanical analysis according to EN 1860 requirements: moisture, ash, heat of combustion, bulk density, mechanical durability, ash melting point, granulometric analysis, fixed carbon and volatiles content, elemental analysis (C, H, N, O, S and Cl)
