Due to the increasing population growth and energy need, interest in renewable energy sources has increased in recent years. Biogas is one of the sustainable energy resources in the world. In 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 wastes is biogas production. In this study, the annual biogas and total annual heat value potential of Afghanistan, depending on the number of animals, were determined. As a result, Afghanistan's biogas potential between ۲۰۱۰ and ۲۰۱۷ is between ۱۱۷۲۳۵۵۸۷۰ m۳/y and ۱۲۸۲۶۹۲۶۱۴ m۳/y. It has been determined that the total annual heat value potential is between ۲۹۱۱۷۱۲۲۳۴۰ MJ / y and ۲۶۶۱۲۴۷۸۲۴۶ MJ /y. As a result, it was seen in this study that the widespread use of biogas in Afghanistan is of great importance in terms of both waste disposal and energy production
