Factors Affecting Pellet Quality

Abstract

The quality of pellets depends on two general factors: (1) the characteristics of the raw material itself, directly related to its chemical composition and (2) the operative variables of the pelletization process, which influence the physical and mechanical properties of the pellets produced. A suitable combination of these two factors is necessary to obtain a qualified energy product. The European Union has established standards, guidelines and thresholds for solid biofuels in order that they can be properly used and marketed as renewable fuels.
