Abstract: A method for recovering resource from waste comprises: a first step for decomposing waste into ash and reformed gas by performing a partial- combustion, a thermal decomposition, and a reforming process with using only oxygen; a second step for pre-processing the ash obtained in the first step; a third step for recycling the ash pre-processed in the second step into resource by a melting process; a fourth step for recovering sensible heat of the reformed gas obtained in the first step, and separating sooty carbon from the reformed gas by a dust-collecting process thereby recycling the sooty carbon into active carbon in an another process; a fifth step for purifying the reformed gas having undergone a dust- collecting process in the fourth step into clean fuel gas by neutralization, desulfurization, and absorption processes, and recycling waste water produced as a byproduct; and a sixth step for utilizing the clean fuel gas obtained in the fifth step. Accordingly, the amount of pollutants contained in final disposal to atmosphere are minimized, and all of the waste is recycled into useful resource. Also, the operation cost (running cost) is reduced significantly.
