Circular phosphorus – better for planet and people

By harnessing the high phosphorus content of renewable sewage sludge ash in EasyMinings´ Ash2Phos process, we are able to produce a domestic cleaner and safer phosphate, while minimising environmental impact.

Phosphate rock, the standard raw material for the production of phosphorus fertiliser, is a finite resource. It is also often contaminated with high levels of heavy metals like cadmium and uranium. Today, these toxic substances are not completely separated out during the production process and tend to end up in the fertiliser being spread on farmland.

The phosphorus content in the renewable, domestic resource sewage sludge ash is many times higher than that of mined phosphate rock. The potential in putting it to use is enormous.

EasyMining’s patented Ash2Phos process extracts more than 90 percent of the phosphorus present in incinerated sewage sludge ash. Through incineration and treatment, undesirable substances are either destroyed or separated out for disposal. It is a truly circular method that enables domestic production of cleaner, safer phosphate.

 

RevoCaP® - Recycled feed and fertiliser phosphate

The high-grade phosphorus (purity greater than 98%) extracted by EasyMining´s Ash2Phos process is converted into a pure, noncrystalline calcium phosphate called RevoCaP.

This can be used as slow-release fertiliser, animal feed phosphate or further processed into conventional fertilisers. Co-products are ferric chloride, aluminium chemicals and sand fraction.

Recycled feed phosphate

EasyMining is working with two projects to demonstrate that calcium phosphates recovered from sewage sludge incineration ashes could be safely and effectively used in animal feed.

Clean Phosphorus initiative

The Clean Phosphorus initiative will work to champion and advocate for phosphorus recovery and recycling processes that are environmentally friendly and sustainable.
