Phosphate rock is an increasingly scarce source of phosphorous, and methods are underway to recover and recycle phosphates from other sources such as human sewage, animal manure and waste ash. ICL Fertilizers Europe's goal is to replace phosphate rock with secondary phosphates. Phosphorus is an essential element for plant growth that cannot be replaced.shortfall in phosphorus will result in a reduction of crop yield. Since the late 19th century, processed mineral phosphorus from mined phosphate rock has been used routinely in European agriculture as a source of phosphate fertiliser. Its use grew significantly in …

Phosphorus Time Bomb for Agriculture? Myth and Reality - Phosphorous Recycling as Green Industry
Fluoride has been, and remains to this day, one of the largest environmental liabilities of the phosphate industry. The source of the problem lies in the fact that raw phosphate ore contains high concentrations of fluoride, usually between 20,000 to 40,000 parts per million (equivalent to 2 to 4% of the ore).detergent and high grade phosphate industry. EC regulations and local environmental objectives are making phosphorus removal from waste waters increasingly widespread. These two facts mean that in the future phosphorus recovery for recycling could become economically viable. The …

An efficient use of phosphorus (P) is necessary as phosphate rock is a finite resource and P is essential for crop production. From the waste sector in the Netherlands, 23 Mkg P is sequestered in landfill, incineration ashes and cement. Flows containing P are discussed, together with options to recover P and reduce P losses, and the ...Thus, up to now no phosphorus recycling with a defrayal of costs is possible. The future importance of phosphorus recycling will depend on the market price for raw phosphate, the recycling costs and, furthermore, on the general political framework.

phosphorus exported from that entity, there is a so-called phosphorus surplus. Such an imbalance of import and export of phosphorus leads to either accumulation in agricultural soils, accumulation in the waste sector or to emissions to the environment. The present report shows that a better internal recycling of phosphorus allows for aTechnologies for phosphorus recycling from water environment. Today, phosphorus is mostly obtained from mined rock phosphate and existing rock phosphate reserves could be exhausted in next 50 – 100 years (Cordell et al., 2009). Phosphate minerals are the main hosts of phosphorus during its environmental transformations.
