Phosphorus (P) is one of the most valuable, but also limited nutrients on earth. Thus, measures need to be taken to recycle P for an ongoing use in agriculture. Especially cereal P in the form of phytate is yet hardly used and thus a promising source for P recovery. The respective process hereby developed includes acidic phytate extraction from rye bran, thermal phytate hydrolysis and subsequent phosphate precipitation as e.g. struvite. Optimized conditions were found to recover 97% of initial P from rye bran in crystalline form, however, still containing organic compounds in the product. Purification steps and evaluation of the process yet seek to be implemented.
