Análise quali-quantitativa dos materiais recicláveis no município de João Pessoa: série histórica do snis (2005-2015)

Abstract

Excessive generation of solid waste and the lack of an environmentally appropriate final disposition, have given rise to socio-environmental concerns, making it necessary to improve and effectively implement waste management strategies. Therefore, the National Solid Waste Policy (PNRS) comes as a tool to assist the management of solid waste in order to reduce the amount of materials produced, through programs such as selective collection. In this context, this work aimed to analyze the selective waste collection of the municipality of João Pessoa (PB) from the database of the National System of Basic Sanitation – (SNIS) from 2005 to 2015 and compare with the data of the city of João Pessoa. The methodology was divided in 2 steps: 1) data collection of the selective collection; 2) organization and analysis of the data collected. Data collection was performed using the following sources: historical series of the SNIS and EMLUR database in the period from 2005 to 2015. By means of the obtained results, an increase in the quantity of materials collected by the selective collection was observed, but a difference of values among selected data sources in relation to the same parameter was verified. In addition, it was identified the lack of data from some indicators provided by the SNIS. There was also an evolution in the number of associations and collectors of recyclable materials, besides the lack of market for commercialization. This makes evident the need for techniques that aim to improve the management of selective collection and a more accurate update of the SNIS database.
