Recycled phosphorus is now being tested as feed phosphate


In January, a new project was started to test the precipitated calcium phosphate (PCP) recovered from Ragn-Sells innovation company EasyMining's Ash2Phos technology. The project is a collaboration between EasyMining, the Swedish University of Agricultural Sciences (SLU) and Lantmännen and it is hoped to show that recovered calcium phosphate from sludge ash has the same level of phosphorus digestibility as conventional MCP (monocalcium phosphate).

- We see great potential for our recovered phosphorus to be used as a feed phosphate and thereby contribute to the transition to a circular economy, says Sara Stiernström, product manager at EasyMining.

The calcium phosphate (PCP) from the Ash2Phos-technology has attractive properties as a raw material for fertilizers and as feed phosphate with a high phosphorus content, low fluorine content and high solubility in citric acid. The solubility is over 90 percent, same level as monocalcium phosphate (MCP) which is used as feed phosphate today. The PCP also has lower CO2-emissions and is more environmentally friendly than virgin phosphorus.
