Abstract: This paper presents the results of the evaluation of the energy potential of waste from the process of drying corn grain in the form of corn cobs, damaged grains, corn grain husks, and mixtures of starting materials. A technical and elementary analysis was performed for the biomass under investigation. The elemental composition of ash and the tendencies for slagging and boiler slagging were determined, and the emission factors were estimated based on the elemental analysis performed. The tests showed the highest calorific value among the starting materials for corn cobs (CCs) (14.94 MJ·kg −1 ) and for the mixture of corn cobs with corn husk (CC–CH) (13.70 MJ·kg −1 ). The estimated emission factors were within ranges of 38.26–63.26 kg·Mg −1 for CO, 936–1549 kg·Mg −1 for CO 2 , 0.85–4.32 kg·Mg −1 for NO x , 0.91–1.03 kg·Mg −1 for SO 2 , and 3.88–54.31 kg·Mg −1 for dust. The research showed that the creation of mixtures from starting materials leads to materials with lower potential for negative environmental impact as well as a reduced risk of slagging and fouling of biomass boilers. However, taking into account all the parameters determined for the biomass under study, the highest energy potential was characteristic for corn cobs and the mixture of corn cobs with corn husk.
