We produced high-density solid biomass (hereafter called Bio-coke) from broccoli, dead cherry tree leaves, and seed of mango based on our patent (PAT.-No.4088933) as one of the utilization methods of various unutilized biomass. The compressive strength of each kind of Bio-coke under room temperature was measured with a compression testing machine. The experimental results showed that the ultimate strength was related to the carbon content of broccoli, seed of mango, and dead cherry tree leaves, and the relations were close to linear.
