Abstract:
Phosphorus (P) is an essential element for organic life and is highly used in agriculture as a main component of many inorganic fertilizers. P is currently extracted from phosphate rock, a non-renewable source. Organic wastes such as sewage sludge (SS) and digested manure (DM) appear as renewable sources of P. P can be extracted from these wastes by acid treatment. This kind of treatment generates a leachate containing P and an organic solid. The implementation of P recovery from organic wastes by acid extraction would require the establishment of the procedure to be followed to recover P from the leachate and also potential uses for the organic solid obtained. The chemical and physical characterization of both streams (liquid and solid) generated during the acid extraction is needed in order to advance in the development of a technology that allows recovering P from organic wastes and using the treated solid. The main goal of the present work is to characterise the products obtained in the acid extraction of digested manure and sewage sludge.
