Evaluación de alternativas de tratamiento y disposición final de biorresiduos de origen residencial en grandes centros urbanos colombianos utilizando criterios técnicos de selección de tecnología

Residential solid waste is mainly disposed in sanitary landfills that do not allow the potential of its biodegradable fraction to be exploited, or a technological alternatives of treatment is selected without a prior in-depth analysis. This happens because defining the right treatment for a specific context is a complex process. So in this project the technological alternatives of treatment and final disposal of residential bio-waste is evaluated according to the technical criteria established in the framework of a technology selection process in the context of Colombians large urban centers. For this, technical criteria reported in different technologies selection methodologies were identified and reviewed with which, the criteria proposed in phases prior to this project were validated, from which 6 criteria were chosen that allow to evaluate differentiating characteristics of technological alternatives. Based on the review and analysis of technical and scientific literature, the commonly used technological alternatives for composting, anaerobic digestion and landfill were characterized. Based on the result of the characterization, the technological alternatives were classified according to each chosen criterion with their respective defined scale of measurement. This serves as a basis to complement the methodology developed in the doctoral thesis in which this project is framed, and makes it easier for the decision maker of a specific project to use it from a more objective technical point of view. According to the obtained results, it was evidenced that the closed composting with forced aeration, the composting in tunnel reactor, the dry, batch, mesophilic and multistage anaerobic digestion, and the bioreactor sanitary landfill are the technological alternatives that present the highest score for the most of the criteria used for its evaluation. However, it would be necessary to complete the other steps established in the methodology developed in the doctoral thesis in which this project is framed to confirm its applicability in the context of the Colombian large urban centers.
