Closing the Loop – Phosphorus Recovery on an Industrial Scale (German Article)
Phosphate fertilizer from recycled sewage sludge ash: Glatt’s PHOS4green technology provides an economically and ecologically viable solution suitable for closing the phosphorus cycle.
Ash-based recycling processes are among the most promising and economically attractive options when it comes to implementing the legally stipulated phosphorus recovery. The first fertilizers produced using the PHOS4green process have been available on the German market since June. The technology, which breaks down the phosphorus contained in sewage sludge ash and makes it reavailable in marketable end products, was developed by plant engineering and process expert Glatt Ingenieurtechnik in cooperation with fertilizer specialist Seraplant.
