The objective of this research is to study the benefits of bagasse utilization in the sugar industry and to propose the alternation of bagasse utilization in the sugar and other industries. The research will be conducted to assess the amount of bagasse used in sugar mills and to consider two factors that reduce the boiler efficiency. The first factor is that boilers use a theoretical high by air in the combustion chamber, but the theoretical air of efficiency boiler is around 140-150%. The second factor is that bagasse use as fuel has a high moisture content of about 50%. Sugar mills need to control these two factors to save more bagasse. From the study, sugar mills should be able to save 20-30% of the bagasse if the theoretical air control and dried bagasse is reduced to 35% moisture content. Sugar mills can take advantage of the bagasse by selling it to the pulp and fiber board industry at the price of 250 baht per ton. Another possibility is that sugar mills can generate electricity by using bagasse as fuel and sell to EGAT. The benefit derived from the bagasse is 294 baht per ton.
