El trabajo de investigaci?n tuvo como fin caracterizar la cadena de reutilizaci?n de residuos generados en el sector de la construcci?n y demolici?n (RCD) en la ciudad de Ibagu?; para el cumplimiento de este objetivo se revisaron los estudios realizados con respecto al dise?o de cadenas de suministro inversa de RCD para tener las bases conceptuales necesarias para dicha caracterizaci?n, despu?s se acudi? al conocimiento de la normatividad vigente respecto a la gesti?n integral de tales residuos, en este caso la resoluci?n 472 de 2017 con base a esto se identificaron los actores que intervienen en cada uno de los eslabones de la cadena en la ciudad de Ibagu? desde la generaci?n y aprovechamiento hasta la disposici?n final. Al tener contacto con los principales actores de la cadena se determin? la estimaci?n de la cantidad de RCD que se generaron en total, al igual que lo que se llev? para la disposici?n final y lo que se arroj? al medio ambiente, con estos resultados se obtuvo que la mayor?a de los residuos generados pertenece a tierra de excavaci?n que es reutilizada para la nivelaci?n del terreno de nuevas construcciones, tambi?n se detall? que existen beneficios econ?micos tras la venta de materiales como el hierro y reducci?n de costos por reutilizaci?n de concreto, finalmente se identific? que el impacto ambiental de tales residuos es significativo puesto que aquellos que no son aprovechados son llevados al medio ambiente causando problemas a la salud y del mismo modo contaminaci?n del suelo, agua y aire.The research work was aimed at characterizing the chain of reuse of waste generated in the construction and demolition sector (RCD) in the city of Ibagu?; In order to fulfill this objective, the studies carried out regarding the design of reverse supply chains of RCD were reviewed to have the conceptual bases necessary for said characterization, then the current regulations regarding the comprehensive management of such waste were consulted. In this case, resolution 472 of 2017, based on this, the actors involved in each of the links of the chain in the city of Ibagu? were identified from generation and use to final disposal. By having contact with the main actors in the chain, the estimate of the amount of RCD that was generated in total was determined, as well as what was taken to final disposal and what was thrown into the environment, with these results it was obtained that most of the waste generated belongs to excavation land that is reused for leveling the terrain of new constructions, it was also detailed that there are economic benefits after the sale of materials such as iron and reduction of costs for reuse of concrete, finally identified that the environmental impact of such wastes is significant since those that are not used are taken into the environment causing health problems and in the same way contamination of the soil, water and air.
