"25000 tpa is alcoa"

"SSC alone produces nearly four times the 25,000 tonnes per annum salt slag that the entire Australian secondary aluminium industry produces.

Alreco processes 100% of the salt slag that is produced in Australia and aims to achieve a similar outcome in the US, and ultimately globally."

"The contract provides for between 33,000 and 39,000 tonnes of salt slag to be processed over a three year period. Alcoa is to pay $300 per tonne of material processed, and retains ownership of the recovered aluminium metal and salt / potassium chloride blend."

so where will the other 12~14kt of salt slag go to if alcoa produces 25,000tpa of salt slag?
