I think it's about zero !!

The benign residue has been studied for it's properties to be used in land reclamation to reduce the acidity of damaged / polluted soil.

But don't my word for this info have a look at this:

Land reclamation residue product

Following receipt of favourable geochemical, geotechnical and material characterisation testwork, Lepidico has committed to a three-month research collaboration with the Department of Earth & Environmental Sciences at the University of Waterloo in Ontario and Knight Piésold, commencing in September 2018. The purpose of the project is to characterise samples of the blended residue streams from the L-Max process and assess this material for use as a by-product in land reclamation applications. The objective is to validate the L-Max residue as a simple, rapid and cost-effective material to assist in the environmental reclamation of city landfill sites.

The Phase 1 Plant FS continues to contemplate the development of a residue storage facility (RSF). However, assuming the land reclamation reside project is successful, the need to have a dedicated RSF on site may be eliminated, thereby making the Phase 1 Plant a ‘zero-waste’ facility, and result in further capital and operating cost savings.

Please check the records to make sure the information is correct Tumby and please "do do" your own research ;-)

Good to have you back on the boards.
Looks like you have timed the re-emargance to perfection.
