Analysis of Brazilian plastic waste management in the global context and case study of the City of Vitória, Espírito Santo
Summary
This review analyzes Brazil's plastic waste management and finds that the country recycles only about 1% of its plastic waste, far behind nations with comparable economic development. Researchers documented extensive microplastic pollution in waterways, atmosphere, and mangrove ecosystems around the city of Vitoria. The study highlights that without significant improvements to waste collection and recycling infrastructure, microplastic contamination will continue to grow in Brazilian environments.
This review analyses Brazil's current stage of plastic waste management, comparing it to what is being carried out worldwide. The Brazilian National Solid Waste Policy established principles and guidelines for solid waste management. However, a decade after its implementation, the results demonstrate timid results about those expected. Brazil's official solid waste and plastics recycling rates are around 4% and 1%, respectively, considerably behind countries with comparable economic growth levels. This work dedicates considerable attention to microplastic pollution, a worldwide concern with potential effects on water bodies, the atmosphere, soils, human health, and vegetal and animal lives. A case study on the solid waste management system in Vitória City, the capital of Espírito Santo, was developed. Besides, a portrait of the pollution in Vitória and Espírito Santo Bays in the atmosphere and mangrove areas is presented. The more critical issues found were the low adherence of the population's city in the selective waste collection (what is reflected in the low solid waste recycling rates), plastic debris, and tiny plastic in the waters, coexisting with heavy metals and hydrocarbons-originated from industrial and anthropogenic activities; microplastics are present in the atmosphere, adding their adverse effects to those of the pollutants already existing in the air and the illegal disposal of waste and the anthropogenic activities which degrade the mangrove ecosystems. A global treaty is being discussed at the United Nations. It's expected that their definitions, initially promised by the end of 2024, will be able to eradicate plastic pollution effectivelly.
