Two stages were developed whose objectives were respectively: 1) to identify the generators of sludge and grease, and 2) to demonstrate the management practices by the managers (companies that provide the service of maintenance, collection and / or treatment of waste generated). At the end of these stages, the flow of these wastes was elaborated in the study area. This allowed us to obtain a compilation of data that describes the way in which the management of this type of waste occurs to generate a vision of the problem in the Valle del Cauca, as a basis for future research on providing technical solutions for handling these. For the year 2014, around 921 industries were found in the study area, of which 85 had wastewater treatment systems (therefore, they are waste generators). On the other hand, 85 waste managers were identified. In this research, 22 industries accepted to participate as well as 5 waste managers. The approximate volume of mud and grease generated by these companies is 367.89 ton / month. Of this amount, only 158.7 ton / month (43%) is used as a soil conditioner, fertilizer, humus or for the substitution of raw materials. In spite of some of the sludge is used, in conclusion, it was identified that environmental policies are required that encourage these alternatives to reduce the impacts on the environment]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen Este trabajo presenta la investigación realizada en cuanto al manejo de residuos (conocidos para este caso como lodos y grasas) provenientes del tratamiento de aguas residuales industriales y domésticas de empresas ubicadas en la zona industrial de Cali, zona urbana y periurbana, y zona franca del municipio de Palmira y Yumbo. Se desarrollaron dos etapas cuyos objetivos fueron respectivamente: 1) identificar los generadores de lodos y grasas, y 2) evidenciar las prácticas de manejo por parte de los gestores (empresas que prestan el servicio de mantenimiento, recolección o tratamiento a los residuos generados). Finalizando estas etapas, se elaboró el flujo de estos residuos en la zona de estudio. Lo anterior permitió obtener un compilado de datos que describe la forma en que ocurre el manejo de este tipo de residuos para generar una visión de la problemática en el Valle del Cauca, como base para futuras investigaciones en torno a dar soluciones técnicas para manejo de estos residuos. Para el año 2014, en la zona de estudio se encontraron alrededor de 921 industrias, de las cuales 85 tenían sistemas de tratamiento de aguas residuales (por lo tanto, son generadoras de residuos). Por otra parte, se encontraron 28 empresas gestoras de residuos. En esta investigación participaron voluntariamente 22 empresas generadoras y 10 gestoras. El volumen aproximado de lodo y grasa que generan estas empresas es 368 toneladas por mes. De esta cantidad, solo 159 toneladas por mes (43 %) es aprovechado como acondicionador de suelos, abono, humus o para sustitución de materias primas. A pesar de que un buen porcentaje de lodo es aprovechado, como conclusión se identificó que se requieren políticas ambientales que incentiven estas alternativas para reducir los impactos sobre el ambiente.]]></p></abstract>
