Technology

Weston Aluminium does not use salt or any fluxes when processing aluminium dross and scrap.

This has resulted in a 50% reduction in the generation of waste to landfill and a significant reduction in energy consumption.

Saltless Process

Weston Aluminium does not produce black dross or Salt slag. The non metallic by-product from its process does not require further stabilisation as it is classed as 'Non Hazardous' and can be land filled. The lack of chlorides in non-metallic particles (NMPs) allows their recycling in various industrial processes such as steelmaking, alumina refining and cement making.

DROSS PROCESSING WITH SALT:

2Mt dross + 400kg Salt = 1Mt Al. Metal + 1.4Mt Salt Slag (Black Dross)
Salt slag needs to be further treated before going to landfill as it is classified as "Hazardous".

WESTON ALUMINUM's NON SALT DROSS PROCESSING:

2Mt Dross + Heat ->1Mt Al Metal + 1Mt non metallic particles (NMPs)
The non metallic particles called ALDEX and ALUMOX can be used in steelmaking, alumina refining and cement making.
