Hydrogen sulfide of toxic gas is produced in landfill sites when the internal conditions of waste layers become anaerobic. This phenomenon occurs easily in landfill sites where construction/demolition waste, such as waste gypsum boards, is disposed. In order to develop control measures against hydrogen sulfide production, experimental studies using a volcanic ash soil containing abundant iron and an iron waste as sulfide capturing materials were conducted. The sulfide ion capturing abilities of the volcanic ash soil and the iron waste were determined by incubation tests with powdered waste gypsum boards. Both materials were revealed to have good capturing capacities or abilities, and suppressed hydrogen sulfide production in anaerobic conditions. And it was suggested that the X-ray diffraction analysis might be applied to estimate the sulfide ion capturing capacity of any proposed material. Finally, we proposed to use volcanic ash soil contained abundant iron for cover soil in landfill sites, and to mix iron waste, such as steel powder, with wastes before dumping.
