The research aimed to evaluate the quality of urban solid waste management, considering
the actions taken and the information provided in the Municipal Plans for Integrated
Management of Solid Waste (PMGIRS). For this, an initial matrix composed of 73
indicators was structured, which went through filtering stages, in order to extract
information with low potential to be answered by municipal managers, giving rise to the
final matrix of 40 indicators incorporated into 7 dimensions, basing the elaboration of the
questionnaires used in this work. Initially, there was the application of questionnaires to
managers to obtain knowledge about the reality of local management; then, the
questionnaires were sent to the experts selected to participate in the Delphi Method. In
total, 5 groups answered the questions on the 7 dimensions, which provided scores from
1 to 5 for each indicator and weights for each dimension. Based on the managers'
responses, on the final grades of each indicator and on the final weights of each
dimension, it was possible to calculate the Solid Waste Management Quality Index
(IQGRS), framing the values found in sustainability levels. Then, the same methodology
was applied to evaluate the quality of preparation of the PMGIRS, being proposed the
Quality Index of the PMGIRS (IQPMGIRS), in this way it was possible to compare what
was being done in practice and what was provided in the text of the instrument. of
planning. As a result in terms of management, 4 municipalities presented unsustainable
conditions, 4 presented regular sustainability, 5 presented good sustainability and only 3
presented excellent sustainability. After the application of clustering techniques in terms
of management, 5 groups were formed, with Inhangapi and Canaã dos Carajás included
in the group with the best performance; Abel Figueiredo, Augusto Correa and Curuçá
were included in the group with the worst performance. Clustering was also applied
regarding the quality of PMGIRS, guaranteeing the formation of 5 groups, with the group
with the best performance being formed by Abaetetuba, Bonito, Goianésia do Pará and
Juruti; the group with the worst performance was composed of Acará and Concórdia do
Pará. The groups with the worst performances reflected the need for investments and
progressions both in terms of management practice and in terms of improvements in
PMGIRS, in order to guarantee the effectiveness of PMGIRS as a decision-making tool. |
