How is odor elimination in a landfill?

Can a landfill explode?
It is highly flammable and can form explosive mixtures with air if it concentrates in an enclosed space with poor ventilation. The range of air concentrations at which methane levels are considered to be an explosion hazard is 5 to 15% of the total air volume. Landfill gas explosions are not common occurrences.
Are we running out of room for landfills?

Almost two thirds of landfill waste is biodegradable. This waste rots and decomposes, and produces harmful gases (CO2 and Methane) which are both greenhouse gases and contribute to global warming. Landfills also pollute the local environment, including the water and the soil.
Are landfills a good idea?
Waste can serve as a source of renewable energy. One type of waste-based energy is landfill gas to energy. Trash, buried beneath a layer of soil in a landfill, eventually decomposes and produces gas. … EPA has identified approximately 400 additional landfills as good candidates for landfill methane to energy programs.

What do landfills smell like?
Methane and carbon dioxide are the major gases produced by the bacterial decay of landfill waste (U.S. Environmental Protection Agency, 1991). Both are odorless. Other gases produced by landfill bacteria are called sulfides. They have a distinct odor that give landfills what many people describe as a “rotting” smell.
Is it dangerous to live near a landfill?
Health is at risk for those who live within five kilometers of a landfill site. … The results showed a strong association between Hydrogen Sulphide (used as a surrogate for all pollutants co-emitted from the landfills) and deaths caused by lung cancer, as well as deaths and hospitalizations for respiratory diseases.
How do landfills affect humans?
Short-term exposures to elevated levels of ammonia and hydrogen sulfide in the air nearby a landfill can cause coughing, nasal blockage, sleeping difficulties, weight loss, chest pain, aggravation of asthma, irritation of the eyes, nose, and throat, headache, nausea, and breathing difficulties.
Can living near a landfill cause cancer?
