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.enNatural Resources, Energy and EnvironmentChemistryEngineering and Applied OperationsConference Presentationhttps://media.tuhh.de/vt3/FSP-Workshop/FSP-Yearbook-2023Presentation
