What is Aluminium Waste?

There are two sectors in the aluminium industry. The primary sector involves the production of new aluminium metal from alumina. The secondary sector involves the recycling and re-melting of scrap aluminium. MHM’s core business is to recycle salt cake and black dross, which are by-products from smelters of the secondary industry. In Australia, MHM also processes white dross, which is another by-product of primary aluminium smelters.

The aluminium recovered by MHM from salt cake, black dross and white dross recycling is re-melted by the secondary aluminium industry.
