Abstract: Corn for animal food is a major agricultural product of Nan, a province of Thailand. Aftercultivation, corncob is burned at cornfields because the farmers need areas for preparing the nextcultivation season. Hence, the remaining corncobs after burning are left uselessly. This agriculturalwaste can be value-added by transforming it to coal. The coal can be sold as an OTOP product (OneTambon One Product) that well substitutes the use of natural coal. Before doing business, it isnecessary to study the feasibility of the project. Therefore, the objective of this research is to studyproject feasibility of corncob coal for commercial purpose. Moreover, the methodology for doingproject feasibility can be a guideline for any other products of other areas. In this research, Maejarimprimary school in Nan province has chosen to be a pilot organization, which runs the business. Thebusiness will help generate more income to people and students who involve in the business.Moreover, the income can be used for supporting education activity for students. This businesssupports the “School in Dream” project of Thai government and the Ministry of Education. Thisresearch covers four areas of study composing of marketing, production technique andmanagement, environment and safety, and financial and economics issues. From marketingresearch, the study shows that major customers are barbeque restaurants, small food shops, andfamilies that use coal for cooking. In production point of view, the results from experiments show thatthe heat coefficient of the coal can be improved by adding some coconut coal into corncob coal andtapioca flour should be added for combining purpose. The weight ratio should be 7:1:2 for corncobcoal: tapioca flour: coconut coal. From environmental and safety study, it is shown that coal burningshould be made far away from accommodation because it may disturb vicinity people. Jobrecruitment and job training are necessary and should be done properly because improper use ofthe coal extruder machine is harmful to the workers. The result from financial and economics studyshows that at 30% sale point of maximum production capacity, the NPV of 73,523 baht will beobtained at 9% interest rate during a period of 10 years and the IRR of this project is 9% for 10-yearperiod.
