Volatile organic and inorganic odorous compounds from various industries are emitted in large quantities and create hazards to the ecosystem and health effects to humans. Thus, the demand for odor and air pollution control systems that provide nuisance-free, breathable air is constantly growing. An international board of authors from universities, research institutes, and industries describe various biotechnological methods ranging from laboratory, to pilot evaluation and to full-scale process implementation. Topics include bioprocesses for the treatment of odors and air pollutants in wastewater treatment plants, rendering plants, chemical production facilities, and food and flavor manufacturing facilities. In addition to the basic microbiological and engineering aspects, the design, modeling and control of bioreactors are also presented.
