Abstract
Anaerobic digestion (AD) is a promising technology to produce renewable energy and reduce organic wastes. Recovering phosphorus (P) from AD residues as easily transportable and marketable products has gained increasing importance for the AD industry to meet regulatory requirements and increase revenue. P recovery from organic wastes such as AD residues is also critical for achieving sustainable food production while reducing P discharge into waters. This review paper provides a critical comparison of the available/emerging physical, chemical, and biological technologies for P removal and recovery from AD residues, as well as the criteria for technology selection and characterization of the end products. Technical, economic, and logistical challenges of different technologies; current operation of full-scale plants; and future research and development needs are also discussed. Opportunities for the integration of P recovery with other beneficial processes (energy production, removal/recovery of other nutrients, production of value-added products, etc.) are highlighted.
