| Description |
Republic of Kazakhstan oil will last for 47.4 years, while gas production - 65.6 years. Given the Kashagan reserves, something else for a longer period, that is a very short periods of time with respect to the development of state and they can be extended only by the development of a technological breakthrough. Along with the question of the ever-growing needs of the population for energy resources, there is a question about the availability of annual waste generation as the impact of the rapid growth of the urban population, which is about 4% per year ("Population" encyclopedia of Astana, 2008). To cope with both problems simultaneously, the waste may be used as energy sources by fermentation technology. Among the urban wastes the organic waste is dominated, such as vegetables, fallen leaves, etc., that have the potential to produce biogas. The use of unsuitable materials as a natural catalyst of fermentation and the time spent on fermentation, are some of the existing barriers to the development of energy resources in urban areas. For this purpose a study was conducted to optimize the ratio of urban waste, animal waste and water in combination with the time of fermentation. The study used an experimental method with the random nature of the two-factor model. The first factor is the ratio of waste, manure, and the second quantity of water - during fermentation, which is fixed to each of 2, 4, 6, 8, 10, 12, 14, 16 and 18th day of the fermentation substrate. The study showed that the optimum proportion to obtain the maximum amount of biogas is a ratio of 500: 200: 300 waste, manure, and water, respectively. Furthermore, on the second day of fermentation the maximum amount of biogas produced.
