Germany introduced a legislation to require the recovery of phosphorus from municipal wastewater in 2017. The ExtraPhos® process from chemical company Budenheim is emerging as one of the country’s promising technology options in this area. Budenheim began developing the phosphorus recovery process “ExtraPhos®” in 2010, forming part of a current wave of investigations in the country. Now the company’s process is emerging as one of the promising options for helping meet the recovery target.
