Aims: This study evaluates the biofuel potential of mandarin orchardpruning residues in the form of pellets.Methods and Results: Pellets were produced at M10 (8 – 10%) moisturecontent, from three different particle sizes (ground by sieves having 4, 6and 8 mm). Some thermal and physical-mechanical properties of thepellets were studied and checked according to the recent EU (EuropeanUnion) standards. Pellet bulk densities varied between 474 kg m-3 and 507kg m-3, while the pellet densities varied between 1230 kg m-3 and 1270 kgm-3 Mechanical durability (MD) values varied from 79.46% to 92.14%.Firmness values changed from 2039.34 N to 2807.40 N. Ash content was5.64% and heating value of the pellets was 18.66 MJ kg-1.Conclusions: The measured physical-mechanical properties of theproduced pellets were in line with the related standards. In addition, fluegas emissions of all the produced pellets were in limits mentioned inheating regulations for the environmental protection aspects for bioenergy resource. Thermal values of pellets are very good as a solid biofuel.Significance and Impact of the Study: Results showed that the pruningresidues of mandarin pruning residues were suitable both in technical andenvironmental.
