The potential of biomass resource is equivalent of approximately 5% of the primary energy aggregate supply in Japan if available untapped biomass resource can be used effectively. Therefore, the unused biomass resource is expected to reduce the degree of dependence to fossil resources. In this study, we targeted woody biomass, agricultural residues and food waste which occupied a large part of annual available quantity of energy and produced high-hardness solid fuel (named Bio-coke) from various kinds of biomass with heating and pressing method based on our patent (PAT.-No.4088933). We have measured the compressive strength of Bio-coke to derive its physical properties at room temperature, and also examined the physical properties of Bio-coke at high temperature (973K) with a particular compression testing machine as assuming its usage under high temperature atmosphere. We contemplated the relation between the compressive strength at room temperature and high temperature for Bio-coke. As a result, there are not any relationships between the compressive strength at room temperature and high temperature. It is conjectured that the difference of the compressive strength between room temperature and high temperature proceeds from the component percentages and organization structure of cellulose, hemicellulose and lignin for each biomass
