Abstract

Hydrogen sulfide in a landfill is reduced by dispersing a hydrogen sulfide control agent, such as an iron compound, into the landfill. The hydrogen sulfide control agent may be a component of an injected foam. Gas is also recovered from the landfill by introducing water into the landfill, as part of the foam, to promote digestion of organic matter.
