Here’s something rather important that you might not know: there may be a worldwide phosphorus shortage within the next few decades. The majority of the world’s phosphorus is currently mined from non-renewable phosphate rock deposits, and widely used in crop fertilizers. Scientists have begun to question just how much more phosphorus is left, and what the agriculture industry will do once it runs out. The answer – or some of it, at least – could be bobbing in a pool of raw sewage. Ostara, a Canadian nutrient recovery company, has developed a method for harvesting phosphorus from municipal wastewater and converting it to fertilizer.

This is another great example of why we should be supporting R & D at universities instead of giving billions of dollars to money losing companies just to keep them alive for another year or two.robo
Sounds pretty good. High amounts of both ammonia and phosphorus are hard to treat with aluminum ferrous sulphate / lime, common treatment in waste water plants... and its not recovered, just treated out of the water into sludge and landfilled.
Wish I knew what their process was.Kuro
One hell of a good idea. I wonder if they have any additives, like edta or something to increase the water solubility for the slow release.JarrodB
