To provide a complex waste disposal system capable of effectively utilizing products generated in a disposal system, and capable of converting gas generated specially in gasification process or methane fermentation process into energy having excellent storage stability and transportability.
The complex waste disposal system comprises; a low-calorific value waste disposal line, which methane fermentation processes low-calorific value waste 10 in a methane fermentation tank 11; and a high-calorific value waste disposal line, which gasifies high-calorific value waste 20 in a gasification furnace 21. In the system, gasified gas 22 generated in the gasification furnace 21 is cleaned by a gas cleaning device 24 to synthesize liquid fuel from the cleaned gas by a methanol synthesis device and a DME (dimethyl ether) synthesis device 27. Preferably, carbonized materials obtained by carbonizing other high-calorific value waste is mixed with a liquid solvent to be slurried, whereby introducing this slurried fuel into the gasification furnace to be gasified.
