PROPOSAL FOR A MANAGEMENT SUPPORT MODEL FOCUSED ON THE SUSTAINABILITY OF SOLID WASTE REVERSE LOGISTICS CHAINS

Abstract

One of the global problems is the management of urban solid waste and this study, which is part of a thesis, aims to propose a management support model focused on the sustainability of solid waste reverse logistics chains. This proposal is based on Enrique Leff's ideas of sustainability and on the assumption that the model proposed by Elkinghton, known as the Triple Bottom Line, should be expanded through the incorporation of cultural and institutional dimensions. In data collection, the Focus Group was used, which had four groups and two rounds. In the analysis, descriptive statistics were used in the quantitative part and Grounded Theory in the qualitative part, using the Atlas TI software as a support tool. The results showed that the 15 experts do not attribute the same degree of importance (weight) to the five dimensions of sustainability, with the environmental dimension having the greatest weight (24%) and the social dimension the least weighting (16%). These experts also indicated that, in order to measure sustainability, 44 guidelines for indicators and indicators are needed. At this point, the results showed that most of these guidelines for indicators and indicators were the same ones already proposed by the authors and presented in the survey of bibliographic reviews.
