RENURE aims to prepare the agricultural sector for the use of ammonium salt fertilisers (ammonium nitrate and ammonium sulphate) by making the transition from research-based field trials to a practical evaluation at the farmer's premises. Stripping and scrubbing as a market-ready, innovative technology makes it possible to recover ammonium salts from manure and use them as a priority of RENURE products.The process consists of two steps: • Stripping: air is blown into the first compartment to remove the gaseous ammonia that is released from the thin fraction of manure or digestate due to increased pH and/or temperature. • Scrubbing: the ammonia-rich air is sprayed with a strongly acidic solution, such as sulfuric acid or nitric acid, to form ammonium sulphate or nitrate, respectively. • The estimated price of the operational installation is approximately €100-150/m3. It requires an annual manure processing capacity of at least approximately 20,000 tons to achieve the desired economic viability.
