Abstract of the Disclosure The invention relates to a process for storing liquid waste in gobs located in natural salt deposits and pro- duced by solution mining. In this process, this waste with a pH of 7 or more, which has been adjusted above ground if necessary, is blended to produce a pumpable mixture, which has a boiling point above 85 °C, flash point above 65 °C, vapour pressure at 60 °C of > 0 to 0.5 kp/cm2, viscosity of less than 300 cP and which forms no toxic or flammable gases. The mix- ture is then conveyed to the storage area and left until phase separation has occurred before the resulting liquid phases are separately drawn off, with the specifically lighter phase being passed on for further treatment whilst the specifically heavier aqueous phase can be harmlessly discharged into the sea.
