PURPOSE: A method for energizing waste and a system thereof are provided to energize the waste by pyrolyzing the waste regardless of the kind of waste. CONSTITUTION: A method for energizing waste comprises the following steps of; sorting the waste into waste, which has the water content of o to 50%, and waste, which has the water content of 50 to 100%; drying the waste, which has the water content of 0 to 50%, using heat and vapor by a hydrothermal method; pyrolyzing the dried waste and the waste, which has the water content of 0 to 50%, at the low temperature; producing synthetic gas by reforming flue gas, which is generated during the pyrolysis, at the high temperature; and heat-exchanging and energizing the synthetic gas which is generated during the reformation. The synthetic gas, which is generated during the reformation, is collected in the drying step and the pyrolyzing step, is heated and then is heat-exchanged, thereby being energized. [Reference numerals] (AA) Selectively dry waste according to water content; (BB) Pyrolyze the waste at low temperatures; (CC) Modify flue gas produced during the pyrolysis at high temperatures; (DD) Recover synthetic gas; (EE) Make the synthetic gas produced during the modification into energy through heat exchange |
