Phosphorus Recovery by Glatt PHOS4green

Waste-free phosphorus recovery from sewage sludge ashes for high-performance fertilizers that comply with the German Fertilizer Ordinance (DüMV) / Regulation EG No. 2019/1009

The Sewage Sludge Ordinance has triggered major changes throughout Germany: Phosphorus recovery is mandatory by law and direct soil-related recycling is no longer permitted. Accordingly, sewage plant operators must review their concepts for sewage sludge disposal and, if necessary, realign them. The challenge is to create sustainable structures that ensure sewage sludge utilization for energy purposes in the long term as well.

Other countries have also responded to the global shortage of phosphorus with regulations, and others will follow. With viable innovations that close the phosphorus material cycle, Germany can take on a pioneering role.

With PHOS4green, we have developed an innovative patent-protected process with which the essential and sought-after nutrient phosphorus can be recovered from sewage sludge ashes and used for new phosphate or compound fertilizers.

Benefit from PHOS4green:

Produce ready-to-use fertilizers from phosphorus recovery from local resources!

Use our PHOS4green process to close the nutrient cycle!

Fulfill the legal obligation to recycle phosphorus economically from sewage sludge!

This distinguishes Glatt technology from other processes:
