    This study presents insights into the solid biofuel properties of corn cob biomass (CCB) wastes for sustainable energy recovery. The physicochemical, thermal, and kinetic properties of CCB were charac-terised through ultimate, proximate, heating value, and thermogravimetric (TGA) analyses. Results showed that CCB contains high carbon (41.88 wt.%), hydrogen (6.33 wt.%), volatile matter (68.21 wt.%), and higher heating (15.70 wt.%) values for potential energy recovery. However, the high ash (16.56 wt.%) content could pose bed agglomeration, fouling, and sintering problems during high-temperature conversion. Thermal analysis resulted in 55.84%-59.51% loss of mass and residual mass of 40.49%-44.17%. Kinetic analyses revealed that CCB is highly reactive as characterised by the average activation energy, Ea=134.58 kJ/mol and pre-exponential factor, ko=2.53×l008/min. In conclusion, CCB is a potentially practical feedstock for sustainable energy recovery through thermo-chemical conversion. © 2020. All rights reserved.
