Calorific value, ash content and ash chemistry are three important parameters in determining the quality of the pellets. Above three parameters is strongly influenced by the raw material for the production of pellets. High calorific value, low ash content and ash chemistry that is friendly to the boiler pipes are ideal conditions sought by users of pellets.Selection of raw materials for the production of pellets is the key word to achieve the ideal condition.
The demand of wood pellets for export on a largescale that the average over 5000 tons / month require the supply of raw material of sawdust or wood sawmill waste in large quantities. It is difficult to fulfill. Small-scale wood pellet manufacturer with a capacity of less than 1000 tons / month may be a going concern. Supply of raw material this is one of the key factor of business success and sustainability of the wood pellets.
Agro-industry wastes such as empty fruit bunches of palm oil, coffee husk, rice husk, corn cob and so as a potential raw material for pellet. Quantity of raw material of the waste is overflow so that a more reliable supply of raw materials, but the quality is still below the wood biomass feedstock based on the three parameters mentioned above.
An ideal way to get the raw materials of adequate quality and quantity although it takes a longer time is to create energy farms or plantations energy industry. Woody biomass can be produced in a relatively quick time and the amount of supply is guaranteed.Land of Indonesia's vast and fertile because of the many volcanoes and tropical climates because it is at the equator so it is very possible for this.
