Análise de cluster para o quantitativo, per capita, de resíduos sólidos residenciais recicláveis, na cidade de Uberlândia-MG

Abstract

The growing production of solid waste in municipalities is an environmental, social and economic problem for city management. Recycling solid residential waste is an important way of reducing waste that goes to landfills, in addition to being a source of income for recyclers and contributing to the health of the environment. The objective of this study was to analyze the behavior of the quantitative per capita (kg) of official collection of recyclable solid waste, by neighborhood in Uberlândia-MG, from January to December of 2020. The methodology of multivariate analysis was used (cluster analysis) hierarchical) in the information on the per capita quantity (kg) of recyclable solid waste from the selective collection carried out by DMAE Uberlândia. The results allowed the identification of neighborhoods that were grouped with similar amounts but whose amounts differed between the groups and this same behavior could be verified for the months. Cluster analysis proved to be effective in identifying groupings of the variables under study, allowing for a distinction to be made between city regions and months of the year with the highest amounts of selective collection; Policies for planning and expanding selective collection; actions to encourage and raise awareness of the correct disposal of recyclable solid waste can be based on studies such as this one in defining its guidelines and procedures.
