By D. Graubard, William Rouleau, and Jean Bogner, Merichem

With many landfills using C&D fines for alternate daily cover, or accepting larger quantities of C&D (construction and demolition) waste, H₂S has become a major problem.

Iron-redox systems provide the lowest operating costs and are now operating in three landfills in the United States, with more in the planning stages.
