The productive transformation process in furs leather developed in the tanning industry generates different types of waste that should have a proper handling. This research consisted of find a separation of waste lime treatment of suede desencalado of the tanning process stage the process of tanning to be used in different applications. Descarnes whitewashed were selected for the implementation of 6 treatments with three replications of deliming through baths with water at room temperature by controlling the factors time in 3 levels (2, 3 and 4 hours) and sulfuric acid as an agent decalcifier at two levels 1 and 2(N). The best results in this process were obtained with the treatment with a concentration of sulfuric acid 2N and an agitation time of 3 hours. Keywords:Deliming; tanning; waste; tannery. ResumenEl proceso productivo de transformación de las pieles en cuero desarrollado en la industria curtiente genera diferentes tipos de residuos que deben tener un adecuado manejo. Esta investigación consistió en buscar un tratamiento de separación de cal de los residuos de descarne de la etapa de desencalado del proceso de curtición que le permitan ser aprovechados en diferentes usos. Se seleccionaron descarnes encalados, para la aplicación de 6 tratamientos con tres repeticiones de desencalado mediante baños con agua a temperatura ambiente controlando los factores tiempo en 3 niveles (2,3 y 4 Horas) y ácido sulfúrico como agente desencalante en dos niveles (1 y 2 N) . Los mejores resultados en este proceso se obtuvieron con el tratamiento con una concentración de ácido sulfúrico al 2N y un tiempo de agitación de 3 horas.
