In the present study, biopellets made of peanut and hazelnut shells and the higher and lower heating values (HHV and LHV) were determined and compared to the standards used in the European Union for biomass-produced pellets. The HHV and LHV of the biopellets made of peanut and hazelnut shells have been determined according to the test standards of the International Organization for Standardization (ISO). The HHV of the peanut shell pellets were determined as 21.01 MJ/kg, 20.13 MJ/kg and 18.05 MJ/kg in moisture and ash free (MAF) base, dry base and the original base, respectively. The HHV of the hazelnut shell pellets were determined as 20.59 MJ/kg and 17.92 MJ/kg in dry base and the original base, respectively. The LHV of biopellets made of peanut and hazelnut were determined as 18.93 MJ/kg and 19.39 MJ/kg in dry base, respectively. The HHV and LHV of pellets made of peanut and hazelnut shells in all bases are suitable to the EN 14918 standard. The ash value of the hazelnut shell pellets were 1.09% and 0.95%, in dry base, air dry base, respectively, according to ISO 1171 standard.
