Woody shells of hazelnut which is a high potential biomass species in Turkey was carbonized in a horizontal tube furnace at 600 degrees C to eliminate the volatiles and to obtain smokeless char. Then, the solid product was briquetted in a stainless steel mold using a hydraulic press under pressure of 50-100 kg/cm(2). In order to improve the mechanical strength of the bio-briquettes molasses and the pyrolytic liquid that obtained during carbonization was used as binding agents. Some parameters such as Shatter index, compressibility strength, and water resistance were considered to evaluate the strength of the briquettes.
