Bottom-Ash Waste Management for Soil Improvement in Saraburi Province, Thailand

Abstract:

Recently, coal is still one of the main sources of energy. From a coal combustion process, a huge amount of coal waste such as bottom ash is generated. The most common method for coal-waste disposal is a landfill which creates the environmental problems. However, the coal-waste utilization like soil amendment is a better way to manage the waste as well as to reduce the environmental impacts and to increase the profit for the manufacturers. Therefore, the objectives of this study are to measure the properties of soil mixed with bottom ash from coal waste and to apply the bottom ash to improve the soil quality by growing one types of plants, chili, and to compare the results with the normal soil and soil with fertilizer. The operating parameters of this study are the compositions of coal-waste mixed with soil and fertilizer ranging from 0 to 30%wt. Furthermore, the pH, bulk density as well as soil texture are also measured and studied. From the results, it is found that bottom ash can help growing both plants especially chili with 10%wt bottom ash.
