There are many industrial processes that produce gaseous effluents with high concentrations of pollutants. Treatment of highly-loaded off-gases has been traditionally performed through physical and chemical processes, mainly adsorption with activated carbons or zeolites, absorption with organic solvents or alkali and acid solutions or catalytic or thermal oxidations.

The management of municipal solid wastes is becoming a global problem. During processing of solid wastes in composting facilities or in landfills, generation of gases with complex mixtures of compounds creates odor concerns and environmental issues. Odorous compounds in this type of facilities are mainly originated from the decomposition of the organic fraction contained in the solid waste. Amongst others, volatile organic compounds, ammonia and hydrogen sulfide are the most produced during the decomposition process.

Odors from industrial facilities are a mixture of a large list of simple and complex volatile, organic and inorganic compounds that produce a physiological response in the pituitary gland since, even at trace level concentrations, most VOCs are malodorous and have very low odor thresholds.

Exhaust flue gases obtained from fossil fuels combustion or other industrial activities contain high amounts of SO_x which must be removed before their emission to the atmosphere. Environmental pollution such as acid rain and photochemical smog is caused by flue gases containing sulfur dioxide and nitrogen oxides. SO_x emissions also affect adversely human health, livestock and plants.
