Sodium chromate—material flow analysis and technology assessment

In this paper the life cycle of sodium chromate as the semi-finished material used for production of all other chromium compounds is presented. The current method of producing chromium compounds has been analysed as well as the environmental hazards posed by production in Poland. Models of a chromium compounds production system which eliminates the need for their storage are presented. Its realisation will transform chromium compounds production, in that this process will be waste-free and raw material costs can be reduced.
