Investigation of Afghanistan's Biogas Potential from Animal Waste

Abstract

Due to the increasing population growth and energy requirement, the interest in renewable energy sources has increased in the recent years. Biogas is one of the sustainable energy resources in the world. In the cattle, ovine, and poultry farming, a large amount of fertilizer is produced in Afghanistan. These wastes are a big problem for businesses, and their evaluation is of great importance. One of the ways to utilize the wastes is the biogas production. In this work, the annual biogas and the total annual heat value potential of Afghanistan are determined depending on the number of animals. As a result, the Afghanistan's biogas potential between 2010 and 2017 is between 1172355870 m(3)/y and 1282692614 m(3)/y. According to the results obtained, the total annual heat value potential is between 29117122340 MJ/y and 26612478246 MJ/y. As a result, the widespread use of biogas in Afghanistan is of great importance in terms of both the waste disposal and the energy production.
