Thermal decomposition and gasification technology is considered one of the most promising technologies for solid waste resource utilization, reduction, and harmless treatment. This review summarizes the basic principle and characteristic indicators of hydrogen production through garbage pyrolysis gasification, as well as the influence of the calorific value and particle size, moisture content and temperature of react, gasification agents, ash melting point, etc. On the hydrogen production through garbage gasification during the pyrolysis gasification process; Then, two typical waste gasification methods are introduced systematically, including the gasification incineration method and the gasification melting method. Finally, the advantages waste pyrolysis gasification technology in carbon reduction and economic efficiency are pointed out, and the application prospects of hydrogen production from solid waste are discussed. The pyrolysis and gasification of waste will become a new development direction in the field of domestic waste treatment and hydrogen energy in the future.
