Recital 10

(10) Only processing methods that reliably yield materials of a consistent quality in accordance with specified criteria should be covered. The Commission’s Joint Research Centre has assessed criteria for the concentration of mineral nitrogen and organic carbon in such materials and has tested the reliability of various processes in producing materials compliant with those criteria. The assessment shows that the following processing methods are capable of yielding materials of a consistent quality in accordance with those criteria: stripping and scrubbing of ammonia to produce ammonium salts, application of reverse osmosis to produce mineral concentrates, and nitrogen-rich phosphate salts (struvite) precipitated out of livestock manure. Therefore, the processes required for the production of RENURE fertilisers which meet the necessary quality to ensure reliable replacement of chemical fertilisers, should be established.
