Zero Effluent: Fertigation in Gravataí

The project aims to promote the reuse (as fertigation for undergrowth) of 100% of all effluents treated at the Gravataí Industrial Complex, avoiding the discharge of treated water into the Gravataí River, reducing adverse impacts on the receiving body, and contributing to the renewal of the deep aquifer.

The initiative improves soil quality by promoting the return of macro nutrients (nitrogen, phosphorus and potassium) to the biological cycle, as well as eliminating the discharge of treated effluent into the Gravataí River, which is already compromised by contributions from domestic sewage and industrial waste.
