Utilization of Ethanol Production Waste for Value Addition
(Project implemented in B.E. 2549) Current government policy has increasingly focused on developing the country's energy sources, reflecting global energy conditions. Thailand, in particular, has abundant biomass energy resources. Energy development efforts have pushed policies promoting alternative fuels such as Gasohol and Biodiesel. This policy has led to the emergence of a new industry: fuel ethanol production. It is well known that ethanol production plants have existed in the country for a long time, but they were primarily for industrial use, such as beverages, pharmaceuticals, or export, with limited production volumes and maximum purity of 95% (containing 5% water), regulated solely by the Excise Department. However, the fuel ethanol industry is different, as it arises from policy mandates and produces fuel exclusively. The Thai fuel ethanol industry primarily uses agricultural raw materials such as molasses and cassava. An approximate assessment of raw material quantities based on the number of fuel ethanol plants with establishment licenses reveals significant waste and by-products. For example, a fuel ethanol plant with a capacity of approximately 150,000 liters/day would generate about 1,500,000 liters of water from the distillation column daily. If the plant does not recycle this water in the production process, all of it enters the wastewater treatment system. Treating 1.5 million liters of wastewater per day requires large land areas or high-investment high-efficiency treatment systems due to the volume. Particularly for plants using molasses as a raw material, the color of the wastewater must be treated before discharge into water sources.
