Abstract

A new approach for the recovery of value-added products from wastes is to search for a synergistic effect from combining two or more wastes. This work improved the recovery of phosphorus and proteins from swine manure by adding a second waste to the manure: fruit waste. The second waste rich in sugars acted as a natural acid generator that replaced the use of purchased acids and lowered the overall recovery cost. In this study, the two model wastes were: swine manure solids (source of extractable phosphorus and proteins) and waste peaches (peaches that were too soft, had bad spots, or did otherwise not meet the grade for sale as fresh fruit). The new process was patented by USDA (US Patent No. 10,710,937). The phosphorus was precipitated with calcium or magnesium compounds, obtaining concentrated phosphate products with more than 90% plant-available phosphorus. The proteins in the manure were separated in a second step. The process recovered > 80% of the phosphorus and proteins in the manure It is contemplated that other sugar-containing agricultural products, such as other fruits and vegetables, could be used in this process for the same purpose with minor adjustments for amounts depending on the sugar concentration and initial pH of the fruit or vegetable.
