To seek an innovative way for simultaneous waste management and energy recovery, two waste materials pine sawdust and disposable face mask were used in the pyrolysis process. Two wastes were used as a carbonaceous material for pyrolysis, and steel slag and Ni/SiO2 were used as a catalyst. The present study pointed the optimistic technical features in line with the use of CO2 in the pyrolysis process. Exploiting CO2 in pyrolysis of pine sawdust and face mask offered a strategic way to control carbon reallocation from liquid to gaseous pyrolysates by the gas phase reactions. The reactions of CO2 and volatile pyrolysates led to CO enhancement, which was only observed at evaluated temperature due to the slow reaction kinetics of the gas-phase reactions. Such the slow reaction kinetic was expedited remarkably with a catalyst (i.e., steel sag and Ni/SiO2). Moreover, CO2 expedited thermal cracking of volatile pyrolysates including dehydrogenation, which led to the enhanced formation of CH4 and H2. Therefore, the thermo-chemical conversion of pine sawdust and face mask could be an environmentally benign way to generating value-added products.
