According to the online news agency ABC Nyheter in Norway, the phosphorous crisis is perhaps the least well-known emergency in the world today. The Norwegian research news website forskning.no says that many scientists are warning of a state of "peak phosphorus," comparable to the expression "peak oil."
[...] "Phosphorous is a finite resource, not only physically, but also politically," says Helness. "Most of it is found in the western Sahara occupied by Morocco, and in China. So, in political terms, it is desirable to identify alternative sources," he says.
Phosphorous is common in sewage water, and the aim of the project is to recover it for use as fertilizer. Currently, a sludge residue that remains after the cleaning of wastewater is used for spreading on fields to improve soil quality.
Save the sweet, sweet night soil. It is precious unto them.

Last time I asked our honeywagon what they did with the stuff, he said they partially treat it at their facility and then sell the liquid and solid products to different companies. If I remember what he told me correctly, they told him that it is a minimum of 1 year of treatment, composting, and strict monitoring until the solids left at the end are considered safe enough to sell to their downstream companies.
