Corn cobs are the cylindrical, elongated central part of the corn ear, consisting of the cob itself and the kernels attached to it. After harvesting the corn kernels for food or industrial use, the cobs are often left behind as agricultural residue. These cobs are rich in cellulose and lignin, making them a valuable biomass resource for various applications. Corn cobs can be utilized in bioenergy production, such as biomass pellets or briquettes for heating, or as feedstock for biofuel production, particularly in ethanol production processes.
