Abstract: Inoue (2005) reported that H2S generation in landfills significantly increases by disposal of waste gypsum board because it contains sulfate and organic matter. Shredded residue generated from sorting facility of mixed construction and demolition (C&D) waste is also suspected of the source of sulfate and organic matter so that it became difficult to dispose of it into non-controlled landfill. However H2S generation was hardly identified in Inoue's study. Then, it is deemed that potential of H2S generation from the residue must be evaluated from the viewpoint of releasing sulfate and organic matter. Several fertilizers and soil conditioners contain both sulfate and organic matter. Therefore, the purpose of this research is to investigate the leaching behavior of materials containing both sulfate and organic matter and to compare it against the residue´s. For this, eleven samples including C&D waste residue, fertilizers and soil conditioners will be used in a serial batch test, to evaluate its long-term leaching behavior. For the obtained leachate, sulfate ion, TOC, VFA (acetic, lactic and propionic acid) and glucose were measured in order to determine how they are different among the samples.
