La Empresa Municipal Obras Sanitarias Mar del Plata que presta los servicios de agua, cloaca y pluvial en la ciudad de Mar del Plata (700.000 hab), desde el año 2000 viene optimizando el tratamiento de los barros cloacales, que poseen un contenido promedio de 91% de materia orgánica y valores de metales pesados muy bajos, debido que la actividad industrial y turística es predominantemente alimenticia. La Planta de Tratamiento de los Barros Cloacales (PTB) generados en la Estación Depuradora de Aguas Residuales (EDAR), consiste en la aplicación alternada de dos metodologías: anaeróbica (MBT) y aeróbica (compostaje termofilico por hileras).Se emplean según las condiciones operativas diarias para obtener una enmienda orgánica segura (Categoría A USEPA y es empleada en el Vivero Municipal local. El soporte utilizado para el compostaje es la poda urbana chipeada previamente. Actualmente se procesan aprox. 4 ton/d de barros primarios aunque no posee restricciones con futuros incrementos en la generación y ocupa un area de 4 ha. Tiene tres zonas delimitadas de: descarga del barro crudo, proceso (2 ha) consistente en 36 plateas de hormigón de 25m x 3,80m y de curado. El sistema de recolección de lixiviados son canaletas individuales para cada platea interconectadas para ser conducidos por una cañería de 500m hasta la EDAR para su tratamiento.De esta forma Mar del Plata (Argentina), y según los ODS 2030, gestiona y trata sustentablemente los barros generados en su EDAR obteniendo una enmienda orgánica forestal de excelente calidad.
