In order to meet the increasing demand for energy and fossil fuels alternative along with intensifying concerns for greenhouse gas (GHG), the demand for global wood pellet market is rapidly escalating. Wood pellet is a solid fuel that is produced by compressing biomass or organic matter. Usually, it is made from waste timber like sawdust, residues of forest and various industrial by products. Its length is 1-2 cm and generally the diameter is 6, 8, 10, or 12mm. At greatest, it is possible to produce 25mm wood pellet. Being extremely thick, it is produced at low moisture, which allows them to burn with high combustion efficiency. Over the other types of solid biomass available, feasibility in transportation, storability and high energy density, among many others are the advantages of using wood pellet and so, it is used as fuels for residential & commercial heating, cooking and generating power.
