Abstract
People in the world have been eating rice for a long period of time, especially in Asian countries including Japan that considers rice as its staple food. Like many agricultural products, agricultural waste like rice husk and rice straw are a big disposal problem. One of the solutions for this problem is solidification. It is better to use the solid as fuel for heating and create a cycle of local production for local consumption. In this study, we established formation temperature and particle size as parameters and produced solid fuel (hereinafter referred to as BIC) from rice husk with high-density and high-hardness solidification technology. The apparent density from weight and volume of BIC and assessed compressive strength of BIC with compression test under room and high temperature was calculated. From derived results physical and mechanical properties were considered. Results showed that rice husk of small particle size had better lignin reaction than large one. However, it is also revealed that the maximum compressive strength at room and high temperature was both weak in the case of crushing the particle size of the rice husk too small.
