A large number of methods for sustainable disposal of red mud was developed, however, it a tendency to use the red mud in other production process, up to 20 % of it until 2025. It was also found that the stabilizing content needed to meet a certain standard differs due to differences in requirements from one country to another. PARTIAL REPLACEMENT IN CEMENT Storage of this unutilized red mud takes vast tracts of usable land and pollutes, land, air and water. As an alternative, dry disposal, involving enhanced dewatering and evaporative drying is also used, whereas in a few occasions sea disposal takes place. Conventional disposal methods involve the construction of clay-lined dams or dykes, into which Red Mud is simply pumped and allowed to dry naturally.
