There was a very interesting essay on #vivianite in Nature Geoscience recently (Slomp 2023). Vivianite could be used to trap excess P in wastewater, preventing it from causing environmental damage in coastal areas, thereby improving water quality for marine creatures. Vivianite formed in wastewater could be extracted and used in agriculture, “nicely closing the terrestrial phosphorus cycle”. Minerals saving the world! #MinCup23
