Traditionally, one of the routes to recover aluminium metal from scrap has been through using the rotary salt furnace process, which also produces salt slag as a by-product.

Not only is salt slag difficult to dispose of, there is the problem of transporting it: it has to be cooled in-house to reach a safe temperature for transportation before it can be taken to centralised salt slag recycling facilities. Altek Salt Slag Presses rapidly cool and compress the material and offer financial and environmental benefits.
