Biogas Production from Poultry Waste
Çukurova Üniversitesi, Tufanbeyli Meslek Yüksekokulu, Adana, TÜRKİYE
Keywords: Biogas, chicken manure, poultry waste

The need for energy is increasing day by day along with the growing world population and rapidly developing technology. As a result of insufficient energy sources to meet the need for energy, search for new sources has begun, and new technologies have been developed in order to have better use of current energy sources and obtain energy from new and different sources. The biogas technology, one of these newly developed technologies, is the leading field for renewable energy production.

In the production of biogas, many plant or animal originated organic wastes can be used as a raw material. Poultry wastes which are one of the most important wastes in poultry enterprises and constitute 25-30% of the total animal waste. These are composed of feces, litter, feed, dead chicks, broken eggs and feathers. Chicken manure is the most important waste materials among them. According to the data obtained from the TSI for the year of 2013 there are a total of 266 million unit layers and broiler chickens and approximately 15 million tons of manure are produced annually. Without sufficient treatment these wastes may pose severe health risks due to creating a suitable environment for the growth of harmful microorganisms and insects, odor, environmental pollution, visual problems and causes the formation of methane gas which leads to greenhouse effect.

These wastes which create some environment problems are the most suitable raw materials for biogas production. Anaerobic digestion is a biological process in which organic matter is degraded to methane under anaerobic conditions. Anaerobic process was carried out at 20-35°C for 40-100 days and this process results in the formation of biogas that is a flammable gas. Biogas is used in many fields such as electricity generation, heating, transportation and in fuel cells. On the other hand, the cost of natural gas can be rediced by mixing with biogas.

Biogas production from poultry waste will provide to meet the increasing energy needs, contribution to the economy and on the other hand will play an active role in the preservation of natural balance.
