ABSTRACT
Attempt was made to produce wood pellets from sawdust using locally sourced binders as an alternative binder, to wood lignin which is a natural binding agent. Wood pellets were produced by manual moulding with starch concentration of cassava and potato starch as the process variable. Results show similar behavior between pellets bonded by cassava, and potato starch, But differs slightly in the case of calorific value and smoke analysis, it shows that smouldering produce the highest quantity of smoke while initial flaming produced the least smoke. Pellets produced from soft wood smoked less. Cassava starch which is cheap and readily available, is therefore a good substitute to potato starch for the production of pellets from softwood for industrial purpose due to it high smouldering ability. While that of convention potato starch is of good substitute for domestic use due it low fins generation, high flaming ability, low smoulding and burring clearly thereby generating only little amount of volatile smoke the domestic atoner and environment.
