In this paper, the analysis of the modern situation of the environment in the process of sintering alumina production is carried out. The data on the technology of preparation of sinter and the situation of environmental equipment are given. Ecological assessment of implemented technological decisions in the sintering department and alumina plant was carried out. There is substantiation for the introduction of additional stages of gases at furnace sintering with the direction of the waste gases of the furnace for the carbonization of aluminate solution. The technical decision in the direction of the gases in the wet treatment in a scrubber-electrofilters and their subsequent use in the alumina production was developed and implemented in the framework of the implementation of ecological engineering in gas treatment of furnaces sintering.
