Dry animal dung fuel
||This article contains wording that promotes the subject in a subjective manner without imparting real information. (October 2012)|
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 and moist dung
The benefits of using dry animal dung include:
- Cheaper than most modern fuels
- Alleviates local pressure on wood resources
- Readily available - short walking time required to collect fuel
- No cash outlays necessary for purchase (can be exchanged for other products)
- Less environmental pollution
- Safer disposal of animal dung
- Sustainable and renewable energy source
- In Egypt dry animal dung (from cows & buffaloes) is mixed with straw or crop residues to make dry fuel called "Gella" or "Jilla" dung cakes in modern times and ""khoroshtof"" in medieval times. Ancient Egyptians used the dry animal dung as a source of fuel. Dung cakes and building crop residues were the source of 76.4% of gross energy consumed in Egypt's rural areas during the 1980s. Temperatures of dung-fueled fires in an experiment on Egyptian village-made dung cake fuel produced
- ""a maximum of 640 degrees C in 12 minutes, falling to 240 degrees C after 25 minutes and 100 degrees C after 46 minutes. These temperatures were obtained without refueling and without bellows etc.""
Also, camel dung is used as fuel in Egypt.
- Tibetan people also use dry Yak & sheep dung fuel.
- Palestine & Arabia used animal and human dung fuel.
- Iran since prehistoric time to modern eras
- In India dry buffalo dung is used as fuel. and it is sometimes a sacred practice to use cow dung fuel in some areas in India. Cow dung is known as ""Gomaya"" or ""Komaya"" in India. Dry animal dung cakes are called Upla in Hindi.

- Bangladesh dry cow dung fuel is called Ghunte.
- Kyrgyz Republic Dung is used in specially designed home stoves, which vent to the outside
- In Mongolia the dry animal (cows or horses) dung fuel is called ""Argol"".
- Maltans used dry cow dung fuel
- Turks and Syrians use dry animal dung.
- Russians dry animal dung is known as ""Kiziak"" which is made by collecting dried animal dung on the steppe, wetting it in water then mixing it with straw then making it in discs which were then dried in the sun. It was used as a source of fuel for the winter and, throughout the summer.

- Dry dung can be used in the production of celluloid for film.
Human feces can in principal 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.
