Dry animal dung fuel

Dry animal dung fuel (or dry manure fuel) is animal feces that has been dried in order to be used as a fuel source. It is used as a fuel in many countries around the world. Using dry manure as a fuel source is an example of reuse of excreta. A disadvantage of using this kind of fuel is increased air pollution.

Dry dung is more commonly used than moist dung, because it burns more easily. Dry manure is typically defined as having a moisture content less than 30 percent.

The benefits of using dry animal dung include:

Also, camel dung is used as fuel in Egypt.

Human feces can in principle also be dried and used as a fuel source if they are collected in a type of dry toilet, for example an incinerating toilet. Since 2011, the Bill & Melinda Gates Foundation is supporting the development of such toilets as part of their "Reinvent the Toilet Challenge" to promote safer, more effective ways to treat human excreta. The omni-processor is another example of using human feces contained in faecal sludge or sewage sludge as a fuel source.

Dry animal dung was used from prehistoric times, including in Ancient Persia and Ancient Egypt. In Equatorial Guinea archaeological evidence has been found of the practice and biblical records indicate animal and human dung were used as fuel.
