Phosphorus recovery and recycling – closing the loop ...

There is a clear and pressing need to better manage our planet's resources. Phosphorus is a crucial element for life, but the natural phosphorus cycle has been perturbed to such an extent that humanity faces two dovetailing problems: the dwindling supply of phosphate rock as a resource, and the overabundance of phosphate in water systems leading to eutrophication.

Phosphate: All hopes rest on Morocco with 75% of

Both phosphate rock production and beneficiation is highly water intensive, and water scarcity may essentially limit the beneficiation in dry areas (Van Kauwenbergh 2010). Many countries that produce phosphate rock, such as countries in the MENA region, already suffer from a shortage of fresh water (De Ridder 2012).
