The study demonstrated that converting spent mushroom substrate into Bio-Coke as an alternative solid fuel is beneficial for mushroom substrate pasteurization. Bio-Coke exhibited better physical characteristics, with high apparent density and mechanical strength, making it ideal for biomass solid fuel applications.
Spent mushroom substrate (SMS), defined as the residual biomass after mushroom cultivation, has been known to cause serious pollution, especially river pollution, as it is produced in large quantities and has been disposed of without consideration of the environment. Thus, there is growing interest in converting this biomass waste into Bio-Coke as an alternative solid fuel to be used in a boiler to generate steam for mushroom substrate pasteurization. This study analyzes the physical characteristics of Bio-Coke conversion from SMS in Malaysia, and it was found to have better physical characteristics than other types of conventional biomass fuel. The results indicate that Bio-Coke from SMS at a formation temperature of 170 degrees C had an apparent density of 1.397 g/cm(3)and a combustion period of 1890 s. Its maximum compressive strength at room temperature (25 degrees C) and 700 degrees C was 105.2 and 5.302 MPa, respectively, which is ideal for a biomass solid fuel. Its high apparent density and mechanical strength provide evidence that SMS Bio-Coke is structurally robust and can remain intact when compressed at high pressure and burned at high temperature in a boiler. Thus, the use of SMS Bio-Coke presents itself as a potential strategy for biomass waste management in Southeast Asia, particularly Malaysia.
