Division BAT 57
United Kingdom
In order to reduce the quantities of waste sent for disposal and to improve the disposal of bauxite residues from alumina production, BAT is to use one or both of the techniques given below.
| Technique | |
|---|---|
| a | Reduce the volume of bauxite residues by compacting in order to minimise the moisture content, e.g. using vacuum or high-pressure filters to form a semi-dry cake |
| b | Reduce/minimise the alkalinity remaining in the bauxite residues in order to allow disposal of the residues in a landfill |
