Division BAT 85
United Kingdom
In order to reduce the quantities of waste sent for disposal from secondary aluminium production, BAT is to organise operations on site so as to facilitate process residues reuse or, failing that, process residues recycling, including by using one or a combination of the techniques given below.
| Technique | |
|---|---|
| a | Reuse collected dust in the process in the case of a melting furnace using salt cover or in the salt slag recovery process |
| b | Full recycling of the salt slag |
| c | Apply skimmings/dross treatment to recover aluminium in the case of furnaces that do not use salt cover |
