Publication // Challenges and Solutions for Biogas Production from Agriculture Waste in the Aral Sea Basin

By Olimjon Saidmamatov, Inna Rudenko, Urs Baier and Elbek Khodjaniyazov. This paper focuses on the potential benefits of biogas production in the Aral Sea region of Uzbekistan. With the announced support of the Government of Uzbekistan, biogas production systems have to opportunity to significantly contribute to improving the economic situation in rural areas via creating employment opportunities, providing access to sustainable energy and decreasing demand for natural resources.

Energy plays an essential role in the modern society and can serve as one of the vital parameters of socio-economic development. Despite developments in technology, over three billion persons living in rural parts of the low- and middle-income countries continue to cover their energy needs for cooking through traditional ways by burning biomass resources. This paper as a case study focuses on the Aral Sea region of Uzbekistan, possessing a well-developed agricultural production with high livestock numbers and intensive crop production. The manure of the livestock farms is not used efficiently and the energy supply of the farms depends primarily on centrally produced gas and electricity. Some areas are not yet connected to the gas grid. Agriculture causes huge environmental damages in its current form. The benefit of biogas production would therefore be fivefold: (1) local energy source, (2) mitigation of environmental impacts, (3) reducing CH4-emissions, (4) producing organic fertilizer as a side product and (5) additional earnings for farmers.
