PGOS4green pilot plant now in Weimar for phosphorus recycling with reduced heavy metal content. Glatt Ingenieurtechnik is using a containerized plant for heavy metal removal from sewage sludge ash as part of phosphorus recovery trials. Thanks to PHOS4green technology at the new demonstration plant, sewage sludge ashes with elevated heavy metal content can be converted into fertilizer granules for the agricultural industry that meet all compliance requirements.
Phosphorus recycling from sewage sludge: more fertilizer, fewer heavy metals: Phosphorus is essential as an agricultural fertilizer. Globally, this indispensable element is becoming increasingly scarce, putting an increasing focus on recovery where natural phosphate deposits are rare. Glatt Ingenieurtechnik GmbH has further developed its patented PHOS4green fertilizer production process so that sewage sludge ash from conurbations with high heavy metal contents can be used. Their removal means that fewer pollutants are released into the environment. Glatt has expanded its PHOS4green process to facilitate the legally compliant recovery of valuable materials from sewage sludge ash contaminated with heavy metals
With PHOS4green, we have developed an innovative patent-protected technology to recover the essential nutrient phosphorus from sewage sludge ashes and use it for new phosphate or compound fertilizers. Recovery of phosphorus from ashes. Direct conversion into fertiliser granules. Heavy metal depletion. Meet us at the CRU Phoaphates 26-28 February 2024 in Warsaw, Poland at stand 36 and learn more about our proven technology.
