Thermal gravimetric change characteristics and gas phase product - CO, NO, $NO_2$, VOCs - generated in the process of pyrolysis and oxidation. were investigated with variation of process parameters including furnace reactor temperature both in pyrolytic and oxidative conditions. For the thermal gravimetric change characteristics. paper and wood were mainly decomposed at lower temperatures and they had similar thermal gravimetric change trend due to their similar compositions; plastics were mainly decomposed at higher temperatures; in the case of textile. natural compounds were decomposed at lower temperatures and synthetic compounds at relatively higher temperatures; food was decomposed in the wide range of temperatures possibly due to their different kinds of components. For the analysis results of gas phase product. the concentrations of NO, $NO_2$ were detected at higher level at the oxidative conditions than at the pyrolytic conditions except that of CO, which is due to complete combustion with sufficient oxygen at the oxidative condition; food gave off CO, NO, $NO_2$ more than the other wastes. VOCs were emitted more at the pyrolytic conditions than at the oxidative conditions.
