The Importance of Phosphate Recovery

Sooner or later, worldwide phosphate reserves will be depleted. Currently, phosphate is seen as a pollutant due to the high amounts phosphate run-off from agricultural lands. In the future, however, phosphate will become a strategic resource since it is only available in limited amounts. It is highly essential that society starts establishing ways of recovering this valuable resource. Phosphate is essential for people, animals and plants as its incorporated in DNA, bones, ATP and enzymes. Annually, 40 million tons of phosphate are mined mainly in Morocco, China and USA. The total world reserves are estimated between 3600-8000 million tons. The production of artificial fertilizer uses by far the most amount of phosphate. 80% of the world phosphate consumption is used for the production of artificial fertilizer. From this, it is clear that in the agricultural sector there needs to be a fundamental mind-switch towards recovering phosphate. Research shows that more than half of the applied phosphate on agricultural fields is lost through run-off and leaching…what a waste!! The recovery of phosphate not only recovers a vital element for life on earth, but it also reduces pollution loads into the environment.
