Caracterização física dos resíduos sólidos urbanos produzidos na cidade de Parintins

Abstract

Nowadays, the city of Parintins follows the model of garbage destination like most Brazilian cities, where the solid waste is deposited in an open-air dump. Thus, as the waste management is an essential activity for any city, this study is focused on the characterization of municipal solid waste in the city of Parintins, as well as the rate of per capita generation of solid waste in the urban population, creating thus, a foundation to support the development of the Integrated Management Plan for Urban Solid Waste of the City. We identified six different routes, which include the whole urban area of the city of Parintins. The routes are: Route 01 Bairro do Palmares and São Vicente; Route 02 Downtown and São Banedito; Route 03 Santa Rita and Castanheira ; Route 04 Santa Clara, Emilio Moreira , São Francisco and Itaguatinga; Route 05 Itauna 1 and 2, União, Paschal Allagio, João Novo 1 and 2; Route 06 Paulo Correa and Djard Vieira. The sample was taken from day and night roadmaps, with daily frequency. After collecting the waste in neighborhoods, we proceeded to the analysis, open-air, where garbage is deposited in the city. Then, the quartering was performed according to Andrade et al. (2004). The route which had the highest average amount of waste was the route three, composed of Santa Rita and Castanheira with 42.48 kg of waste, and the lowest was the route two, held at Downtown and in São Benedito. It was observed that the largest fraction was organic matter (50.97 %), followed by plastic (23.94 %), paper and cardboard (13.85%), other components (cloth, burlap, glass, stone, leather and rubber) with 9.42 %, and metals (1.79 %) . The apparent specific weight produced in the city of Parintins was 179.27 kg/m3 and moisture content in the solid waste produced in the city of Parintins was 15.75%. The determination of per capita generation of solid waste was 1.56 kg/person/day in the urban area of the city. Through the results obtained in the survey we found the need of developing effective and permanent environmental education programs, with proposals to change the consumption patterns of the population , seeking minimization of waste, better use of products and assets acquired, and collaboration of people with selective collection, aiming to educate citizens committed to the quality of the environment and the management of waste in the city.
