Ann: PET Secures Global Rights to Reusable Recyclable Product, page-9

Thanks Relax

Great find. Interesting read. Here are 2 excerpts.

"It is predicted that the phosphate supply will fall below the demand for agriculture by 2033, and that raises a major food security concern"

"The United States has about 2500 lakes which are either eutrophic or hypereutrophic and they need immediate (and subsequent) clean-up to make the lakes productive and their water usable)"

When I first saw that the removed P could be reused as fertiliser I thought that it was a nice aside. Now I see that the ongoing supply of P is actually a major global concern in its own right.
