Abstract

Solid waste management has become one of the most significant environmental problems to be faced by the government, due to the growing generation of waste. Inefficient management solid waste may result in a number of environmental, social and economic consequences. In attempt to minimize these consequences, in 2010 the National Solid Waste Policy was created, which through its instruments, principles and objectives seeks to become Brazilian solid waste management more sustainable. To ensure that a management system is sustainable it is necessary to evaluate its activities and correct its possible faults; and for this the sustainability indicators is a useful tool. Therefore, after extensive bibliographical review, the present work adapted and applied a group of solid waste sustainability indicators in Coromandel - MG. First, the adaptation of a methodology was carried out considering the particularities of the municipality and the National Solid Waste Policy. After the adaptation, the group was applied, and finally, adjustments were proposed in the current system according to the results. The indicators were classified qualitatively, in favorable, unfavorable and very unfavorable indicators; and quantitatively, with the assignment of grades 5, 3, and 1. Between the fifteen resulting indicators only one was classified as favorable, six as unfavorable and eight as very unfavorable. Analyzing quantitatively, that in an ideal situation all indicators would score 5, resulting in a total of 75 points, after review, the municipality obtained a total of 31 points. Therefore, according the results, the predominance of very unfavorable indicators tends to a low sustainability in the solid waste management.
