Mardie has been designed to produce 5.35Mtpa of high-purity salt (>99.5% NaCl) and 140ktpa of Sulphate of Potash (SOP) (>52% K2O) via solar evaporation of seawater.

Using an inexhaustible seawater resource and a production process driven mainly by natural solar and wind energy, Mardie will be a sustainable supplier to the global salt and potash growth markets.

Project economic despite capital costs
