Indicadores de sustentabilidade para avaliação da coleta seletiva de resíduos sólidos urbanos em Aracaju-Se

Abstract

The area of solid waste management is of vital importance to any city. In the city of Aracaju/SE, this is no different and this research aimed to contribute in the sense of proposing the use of sustainability indicators, selected with correlation to selective collection and within the environmental, economic, institutional/operational and socio-cultural dimensions, and thus evaluate the system of selective collection of urban solid waste in the city by means of a sustainability matrix. Alongside this research, a gravimetric study of municipal solid waste was also carried out. The methodology employed was based on a descriptive, exploratory, qualitative, and quantitative study format, with a specific bibliographic survey, as well as observations, records and data collection. The results obtained from the gravimetric study showed the potential for developing work aimed at composting waste, as well as the need to expand environmental education throughout the city, specifically with selective collection. As for the level of sustainability, its final score was enough to classify the system as medium sustainability (NS = 5.20), where the order of performance of the dimensions in the matrix found was: economic < environmental < institutional/operational < socio-cultural. It is therefore believed that the municipality's administrators should pay attention to the indicators proposed in this study, to improve their weak points (economic dimension) and enhance their strong points (socio-cultural dimension), and thus achieve continued improvements in solid waste management.
