Resíduos sólidos urbanos : impactos da emissão de CO2 dos aterros sanitários dos municípios de Jaboatão dos Guararapes, Escada e Altinho no Estado de Pernambuco, Brasil.

Abstract

Concerns about climate change have grown over the years and gained momentum in the scientific, social and political spheres. Despite the global reach, pollution- generating effects, their consequences and mitigation actions, occur at the city level. The problem of urban solid waste grows as the population, consumption and economy of cities grow. In 2010, the National Policy on solid Waste was launched, aiming to end the dumps and establishing new standards for the management of waste in landfills. In this scenario, the main objective of this research is to analyze the relationship between landfills and climate change in the cities of Jaboatão dos Guararapes, Escada and Altinho. For that, the treatment units of the landfills, the amount of waste stored, the CO2 emission produced and the surrounding area were analyzed. We used the satellite images of Google Earth and the count of CO2 emissions by the SOS Mata Atlântica tool. Among the main results, it was observed that in order to adapt to the new policy, the small municipalities organized themselves into consortia to manage a landfill that would serve all members. In addition, it has been observed that the main impact of landfills on climate change is air pollution from the emission of biogas from the decomposition of waste, further contributing to global warming.
