Dear Snowdrift,

Thank you for your question. Please don’t hesitate to ask whatever questions you have in mind and don’t worry whether it was asked before or not.

I would like to confirm and assure you that Elysis’ technology wouldn’t affect the use of Drosrite™ system in the aluminum industry.  Basically, Elysis’ technology would replace the carbon anodes in the aluminum smelting process with inert anodes, which would produce oxygen as a by-product instead of carbon dioxide.

As for PyroGenesis’ DROSRITE™ system, it is a sustainable process for maximizing metal recovery from dross, a waste generated in the metallurgical industry such as in aluminum smelting. The dross is caused by oxygen coming into contact and reacting with molten aluminum to form a “scum” or “oxide phase” on top of the metal pool. The oxides act like a sponge, floating on the surface and soaking up metallic aluminum beneath it. As such, significant amount of valuable aluminum will be lost when trying to skim the oxides out.

Having said that, it is important to understand that whether the smelting process is environmentally friendly (“green”) or not, a waste stream will still be generated during the aluminum smelting process and will still need to be treated in order recover the valuable metals it contains. PyroGenesis could complement the Elysis’ process by eliminating carbon emissions and wastes from landfill. Combined, we could address a significant portion of smelter’s environmental issue

I hope this helps.
