This study was aimed at reducing CO₂ emission from incineration of waste. The fundamental idea is that the incineration process is divided into a high-temperature pyrolysis of waste and a combustion of gaseous products of the pyrolysis, and part of the constitutive carbon atoms in waste is fixed as solid carbon in ash. In addition to gas range, microwave heating is employed to avoid the difficulties originating from the very small effective thermal conductivityes of waste in the pyrolysis process. Photo process copy paper was used to represent waste in this study, since more than half of office waste is wastepaper. The pyrolysis process was tested in a microwave oven as well as in an electric furnace. The results show that two-thirds of the constitutive carbon atoms in the paper are fixed in the residue. After subtracting the amount of CO₂ emission from a thermal power station for the electricity needed by the microwave heater, 35% of CO₂ emission is reduced as the net.
