Coal-coke is required a lot of performance in a melting furnace. Therefore, Coal-coke has 2OMPa of high mechanical compressive strength under room temperature, cold strength. The high mechanical cold compressive strength is very important factor for Bio-coke (named at Kinki University) as the substitution for Coal-coke. Especially, Bio-coke is required itself performance for mechanical compressive strength to keep air passage into the melting furnace as well as Coal-coke. This study proposes a simple nondestructive method for hardness evaluation with Bio-coke produced from apple juice residue, mainly non-utilization biomass on Aomori Pref. The mechanical properties have been measured by Brinell hardness and cold compression test to obtain the fundamental database with production conditions, initial moisture, process heat temperature, etc. In particular, the cold hardness of the Bio-coke is influenced by process heat temperature. This study suggests that Brinell hardness test can apply effective means as a simple and easy evaluation method of the Bio-coke in comparison with the cold compression test.
