In recent decades, a new generation of waste treatment plants based on biological treatments (mainly anaerobic digestion and/or composting) has arisen all over the world. These have been progressively substituted for incineration facilities and landfills. Although these evident benefits in terms their environmental impact higher recovery material energy, release into atmosphere malodorous compounds its mitigation is one main challenges that face. this review, methodology to determine odors, causes having undesirable gaseous emissions, characterization odors are reviewed. Finally, another important topic odor abatement technologies treated, especially those related low-impact processes. conclusion, control challenge sustainable implementation modern plants.
