Modelo de aprovechamiento sustentable para los residuos sólidos orgánicos generados en Bogotá D.C., involucrando organizaciones de recicladores de oficio

Abstract

This research proposes a model for the sustainable use of organic solid waste generated in Bogotá, with the involvement of professional recycling organizations. The model’s construction was based on the characterization of the city’s public sanitation service and relevant international case studies. These served as references to identify key technical, economic, environmental, and social factors, which were used to create the theoretical model and develop strategies for its implementation. One of the strategies consisted of developing an integrated management plan for solid organic waste generated in households that included: awareness-raising, separation at the source, selective collection, transportation and use of composting and vermiculture systems. Another strategy was the use of geographic information systems (GIS) to generate a priority management zoning proposal for organic waste generated at the locality level, as well as the generation of some strategies for the commercialization of products derived from the transformation processes in the utilization plants. A pilot test of the model was conducted in four neighborhoods near the Doña Juana landfill, involving 200 families and a recycling organization. During this test, the families’ and recyclers’ responses to the model were evaluated. With this information, the initial theoretical model was adjusted, and scenarios were developed for its implementation, as well as the generation of a proposal for a tariff framework for the use of organic waste by professional recyclers.
