Zusammenfassung:	Methods and apparatus for controlling odors in an enclosed space, such as a pit latrine, include providing an oxidizer, such as a catalytic heater and an optional mechanical ventilation unit, such as an inline fan, both flow connected to a vault (pit) of the latrine. The heater is also connected to a source of fuel, for example, propane. Fresh air is drawn through vents in the latrine housing and thereafter through toilets in the latrine and through the vault, providing oxygen for the reaction. The fan and/or oxidation process draws both fresh air and accompanying odorous compounds directly from the latrine and into the oxidizer wherein the odorous components are substantially destroyed.
