From sewage sludge ash to a recycled feed phosphate – digestibility of precipitated calcium phosphate in broiler chickens and growing pigs

•Precipitated calcium phosphate show satisfying digestibility for chickens and pigs.•In vivo digestibility of precipitated calcium phosphate was tested.•Recycled feed phosphate from sewage sludge ash can replace mined P.•The recycled feed phosphate fulfilled the quality demands in feed legislation.•Recycled P in animal feed align with EU’s green deal and farm-to-fork strategy.
