Resource recovery from ash after incineration of wastewater sludge

Resource recovery from ash after incineration of wastewater sludge

The dried sludge from the wastewater treatment plants (WWTP) is mostly burned in the Netherlands. Nowadays this WWTP sludge is considered as a potential source for any minerals and metals, like phosphate. A economical sustainable way to recover phosphate from the wastewater sludge is burning the sludge and recover phosphate from the ashes. Beside phosphate WWTP sludge contains also other materials, which end up in the ash after incineration of the wastewater sludge, metals such as Zn, Cu, K, etc. The challenge for the team is to come up with possible methods for recovering elements like Zn, Cu, K, etc. from the ash of burned wastewater sludge on a technical and economical way.
