Abstract
Currently, various energies such as fossil fuels and nuclear power are considerable expenditures. Resource depletion and environmental issues are taking place by activation of various problems and economic activity due to population growth in developing countries. However, in order for society to develop, energy, such as natural energy, is required have been studied for this purpose. A variety of energy including conventional type energy is needed. In this study, using Bio-coke that has attracted attention as a natural energy, a research was conducted using rice bran, which is an unused biomass in Thailand. By adding rice bran to 2-mm pulverized wood waste materials in making Bio-coke, it was found that Bio-coke density increased proportionally with increase in rice bran ratio. Results also showed that by adding rice bran in the raw material, it is possible to simultaneously improve both the gross calorific value and cold compressive strength. Moreover, reduction in environmental impact is also possible in the production process by optimizing the production conditions.
