Precipitated phosphate salts and derivates are obtained out of varied input materials including waste. They are reach in phosphorus, which is an essential nutrient in agriculture. The recovery of phosphorus is important for the circular economy. The use of precipitated phosphate salts and derivates is safe for human, animal and plant health, and for the environment. It has agronomic efficiency. The Commission will adopt an act setting the conditions for their use in EU fertilising products.
