Empresa Metropolitana de Abastecimiento y Saneamiento de Aguas de Sevilla, S.A. (EMASESA, in English Metropolitan Water Supply and Sanitation Company of Seville) carried out a market consultation as part of this innovation procurement process.

EMASESA needs a new integrated model to manage sewage sludge and other organic wastes in order to address operational limitations and to adapt the system to new regional regulation about the use of sewage sludge for agricultural application. 

EMASESA’s new sewage sludge management system must be suitable for the long term, sustainable in its three dimensions (social, economic and environmental) and must facilitate a correct closure of the urban water cycle and, preferably, it must be based on circuits of circular economy that allow the creation of value in the environment from the waste generated by the public water supply and purification service to the population.
