Objective met in 2017 (in regard to the objective for 2021) 


The Granada Sur wastewater treatment plant (WWTP), through its road map 'Zero Energy, Zero Waste', is focused on becoming energy self-sufficient in 2020 through the recovery of its effluents and the generation of surplus energy that will be injected into the local network.

In 2017, the WWTP had already achieved the task of self-supply of 82.6% of its energy consumption. In addition, the water that is produced is reused to irrigate nearby woody crops, the digested sludge is used as an agricultural fertiliser, and the grease and silt are made into compost for garden use.


"Traditional production processes are based on unlimited availability of resources, but resources are not unlimited, so we need to reconsider the pattern of consumption and production. At SUEZ in Spain, we promote initiatives such as the biofactory, a clear example of application of the circular economy in the territory, and a commitment to lengthening the life cycle of resources by reincorporating them into the production cycle."
Pilar Rodríguez, Functional Manager, Head of Circular Economy Projects


At SUEZ we are committed to the Circular Economy as a logical, viable and sustainable alternative, as a way to preserve our natural resources and regenerate value over time.
