There are different classes of Zeolite...and the has been touched on before in company presentations, as I've mentioned.

Additionally, I believe Lithium mining companies, especially in WA, are paying enormous amounts to truck their waste and dispose of it in holes in the ground. Any business case simply needs to look at the current cost of disposal, and the enormous "environmental" cost!!!!!
Then consider that the waste can be transformed in to a saleable product.

I suggest you read all the companies previous announcements.
