The electrolysis of aluminum in Tajikistan is represented by the only SUE Talco enterprise. A feature of the enterprise's production activity is its dependence on the raw materials supply from behind of borders Tajikistan. Possibilities of development of its own mineral base are hampered by the seasonal imbalance of the Tajikistan power system based on unique hydro resources. Partial compensation of raw materials for electrolysis can be provided by recycling of gas purification waste which for last years of the plant operation more than ten million tons are saved up. The only condition for such formulation of the question consists is the need to develop technology capable exploitation in summertime when energy is excessive is used, usually insufficiently rationally.
