A destinação dos resíduos sólidos por diferentes classes econômicas do município de uberlândia - MG

Abstract

The increase of population in urban areas directly influences the production of solid waste, requiring the correct disposal of these materials. Several municipalities have created programs that aim to promote the collection of materials from the recyclable fraction, as recommended by Law 12.305/2010. However, after the program is implemented, it is necessary to constantly monitore it in order to make it increasingly sustainable and efficient. Thus, the analysis of the destination of recyclable waste from different neighborhoods is an important tool to act in critical points and failures of management systems and waste management in municipalities. In this sense, this work aims to analyze the influence of economic classes in the disposal of solid waste in the municipality of Uberlândia. Twenty-four neighborhoods in Uberlândia included in the Selective Collection Program from 2017 to 2020 were analyzed comparing the amount of common solid waste that is sent to the landfill with the amount of recyclable waste that is sent to the associations and cooperatives of waste pickers in the municipality, by neighborhood and their respective incomes. The results indicated that higher economic class neighborhoods allocate more recyclables to selective collection in the municipality than lower economic class neighborhoods, as an increase in income will contribute to an increase in consumption, rising the fraction of recyclables present in solid wastes (CAMPOS, 2012). The Saraiva neighborhood, of economic class B2, destined, in the period surveyed, 6.28% of the total waste generated for selective collection; the neighborhood Presidente Roosevelt, of economic class C1, destined 1.89% for selective collection in the municipality in the same period. It is expected, therefore, that this work will help the municipal government to create strategies to act in neighborhoods of different economic classes, approaching the greatest potential that can be obtained in relation to recycling.
