  • Recovery of phosphorous from poultry litter
    Patent number: 8936663
    Abstract: A chemical extractant selected from solutions of K2SO4 and/or Na2SO4 can be used by contacting with untreated broiler litter to selectively and efficiently remove phosphorous from the broiler litter. The broiler litter and extractant solution mixture, after a suitable time, can be separated, such as by filtration. The resulting treated broiler litter is thus significantly lower in P content without being lower by an undesirable amount in more preferred minerals. The treated litter so obtained is suitable for crop soil augmentation. Further, phosphorous can be thereafter precipitated in the form of phytic acid. Since the precipitate is high in mineral content, it can be used for other purposes (e.g., plant food, etc.).
