As I said, after studying the matter, we agree with you that we should keep a percentage of phosphates for certain industries, or for health services. We are in favour of that position.
However, some other scientific studies, which I don't have with me, talk about salt-based products that could eventually replace phosphates. I don't have the exact term, but I have it in my documents. It's not fully developed yet. To answer your question, you'll have to retain a certain phosphate level in some industries and hospitals; that remains to be seen.
