Economic analysis of biogas production from small scale anaerobic digestion systems for cattle manure

Abstract

One of the major concerns of biogas plants can’t be operated economical and environmental sustainable manner. Inorder to produce biogas in rural areas, using anaerobic systems with high organic content of farm wastes can be ableto remove these concerns. The production of biogas can then be used for cooking, lighting and heating. Biogas is agood alternative to kitchen gas cylinder. However, there is a lack of knowledge and experience available on designmethods for these systems. Anaerobic digestion is generally economically applicable waste treatment systems forlarge farms (>100 cattle). However, majority of Turkey farms have less than 100 cattle, making this technologyeconomically inaccessible to the vast majority farms. The objective of this study is to determine the economic viabilityof small scale anaerobic digester systems taking into account on domestic production conditions.
