Abstract
Hydrogen sulfide (H2S) has become recognized as a problematic gas emitted from landfills. Sulfate, which can produce H 2S in a landfill, is in drywall in construction and demolition (C&D) debris and sometimes products or recycling. This research consisted of examining alternative treatment of H2S gas at landfills, input/output of sulfur at landfills and generation/prevention of H2S in the landfill setting using C&D. In this research, four ashes were tested with landfill gas to investigate H2S attenuation, the highest attenuation reached was 73.8mg of H2S per gram of ash. In addition, these exhausted ashes, as well as sulfur cake were placed in a landfill simulated environment to investigate if they could regenerate H2S and from the results, appears that sulfur cake is most likely to regenerate H2S. The experiment involving the prevention of H2S showed that it is unclear whether these materials have the ability to inhibit the production of H 2S.
