Performance evaluation of the solid waste collection in municipalities of the state of Pará: proposal for a multivariated indicator

Abstract

The growth in solid waste generation has made its management an essential service for cities, with household and selective collection being fundamental parts of this process. Thus, the objective of the article was to create a Solid Waste Collection Indicator (SWCI) in the municipalities of Pará, based on data from the National Sanitation Information System. The methodology was based on the application of factor analysis that enabled the creation of an indicator, encompassing variables related to organized selective collection, coverage of urban household collection and legislation on solid waste. The results showed that 90% of the 20 municipalities analyzed showed improvements in their ICRS, between the years 2012 and 2018, but they also show that the enactment of legislation is not a fundamental factor in the implementation of selective collection systems. Thus, more effective public policies are necessary for the municipalities of Pará to achieve better results in the management of their solid waste.
