En este trabajo se presenta la caracterización físico-química de aceites usados de motor de una muestra de empresas del sector industrial de Mamonal de la ciudad de Cartagena de Indias, entre las características tenidas en cuenta estuvieron: densidad, porcentaje de humedad, viscosidad, metales en suspensión y poder calorífico superior, algunos de los métodos utilizados fueron: densimetría, karlfischer, viscosimetría y absorción atómica. Se resalta que en las muestras analizadas no se reporta una presencia significativa de estaño, plomo, cromo, plata y cadmio. La presencia de calcio, magnesio, sodio, zinc, fósforo puede ser producto de los aditivos que se emplean para mejorar sus características. La presencia de Cromo y Hierro en las muestras se interpreta como indicio de desgaste de piezas. El silicio encontrado puede ser aportado por filtración de polvo. Acorde con lo anterior y un adecuado tratamiento estos aceites son susceptibles de reciclarReferences
