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.

1. A method of forming a system for controlling odor from substantially enclosed space in fluid communication with a vault, wherein the vault is configured to store solid and liquid waste provided from the substantially enclosed space, wherein the method comprises: providing a flameless heater configured to perform an oxidation reaction on odorous air to produce deodorized air;fluidly connecting the vault with the flameless heater using a first conduit positioned between the vault and the flameless heater, such that the flameless heater is in fluid communication with the substantially enclosed space via the first conduit and the vault;attaching a second conduit to the flameless heater, wherein the second conduit is configured to emit the deodorized air from the flameless heater; andpositioning at least one fan within the first conduit between the vault and the flameless heater, wherein the at least one fan is configured to draw in the odorous air from the vault and the substantially enclosed space and to direct the odorous air to the flameless heater. 2. The method of claim 1, wherein the at least one fan is in continuous and uninterrupted one-way gas flow communication with the substantially enclosed space such that ambient air is drawn from the substantially enclosed space through the vault to the flameless heater. 3. The method of claim 1, wherein the flameless heater includes a catalytic heater. 4. The method of claim 1, wherein the substantially enclosed space is a user space of a latrine. 5. The method of claim 4, wherein the user space of the latrine includes a toilet fluidly connected to the vault. 6. The method of claim 1, wherein the substantially enclosed space is a confined animal feeding operation space. 7. The method of claim 1, wherein the substantially enclosed space defines a vent such that fresh air is drawn into the substantially enclosed space via the at least one fan through the vent. 8. The method of claim 1, further comprising cycling operation of the at least one fan and the flameless heater based on a time dependent schedule to optimize fuel usage. 9. The method of claim 1, further comprising fluidly connecting an exhaust vent stack attached to the vault to the first conduit. 10. The method of claim 9, wherein the at least one fan is positioned in the first conduit between the exhaust vent stack and the flameless heater and configured to draw in the odorous air from the vault and the exhaust vent stack. 11. The method of claim 1, wherein the second conduit is configured to direct the deodorized air towards the substantially enclosed space. 12. A method of controlling odor from a substantially enclosed space in fluid communication with a waste holding chamber, wherein the waste holding chamber is configured to store solid and liquid waste provided from the substantially enclosed space, the method comprising: providing a system for controlling odor, the system comprising: a flameless heater configured to perform an oxidation reaction on odorous air to produce deodorized air;a first conduit attached to the waste holding chamber, wherein the first conduit fluidly connects the waste holding chamber and the flameless heater;at least one fan positioned within the first conduit between the waste holding chamber and the flameless heater; anda second conduit fluidly connected to the flameless heater;drawing the odorous air from the substantially enclosed space and the waste holding chamber to the flameless heater through the first conduit via the at least one fan;treating the odorized air using the oxidation reaction in the flameless heater to produce the deodorized air; andexhausting the deodorized air via the second conduit. 13. The method of claim 12, wherein the at least one fan is in continuous and uninterrupted one-way gas flow communication with the substantially enclosed space such that ambient air is drawn from the waste holding chamber to the flameless heater via the first conduit. 14. The method of claim 12, wherein the substantially enclosed space is a user space of a latrine. 15. The method of claim 14, wherein the user space of the latrine includes a toilet fluidly connected to the waste holding chamber. 16. The method of claim 12, wherein the substantially enclosed space is a confined animal feeding operation space. 17. The method of claim 12, wherein the substantially enclosed space defines a vent such that fresh air is drawn into the substantially enclosed space via the at least one fan through the vent. 18. The method of claim 12, further comprising cycling operation of the at least one fan and the flameless heater based on a time dependent schedule to optimize fuel usage. 19. The method of claim 12, wherein an exhaust vent stack attached to the waste holding chamber is fluidly connected to the first conduit. 20. The method of claim 19, wherein the at least one fan is positioned in the first conduit between the exhaust vent stack and the flameless heater; and wherein drawing odorous air via the at least one fan further comprises drawing the odorous air from the exhaust vent stack. 21. The method of claim 1, wherein the system is retrofitted onto an existing vault in fluid communication with an existing substantially enclosed space.
