The purpose of this study is to analyze the effect of ratio composition and particle size on pelletization of various feedstocks. The feedstock materials were used leaves, wood, junk waste, shells of coconut and combination of any kind of pure feedstock materials with composition ratio 75:25, 50:50 and 25:75. The feedstocks with highest calorific value crushed and filtered using variation of mesh (20,40,60,80,100 and 120mesh) before pressing in mold dies diameter 6.5mm using multiple pellet press at 70kg/cm² . The results showed that combination with wood results higher calorific value of feedstock, and larger particle size impact lower durability and lower density.
