| Abstract: | Five methods to reduce the negative influence of soda ash factories on the natural environment are presented: 1. obtaining calcium–magnesium phosphates by treating the suspension from raw brine purification (H3PO4), 2. production of precipitated chalk from soda processing waste, 3. production of gypsum and semi-brine, 4. desulphurisation of fume gases from the factory power plant, and 5. utilization of distiller waste. The laboratory scale tests showed the high efficiency of these methods. Economic analysis has proved that only four out of the five presented processes can have a positive financial effect on soda ash factories, as well as being well justified economically. The value of two of the innovations presented is confirmed by their implementation in factories. |
