Avaliação ex post dos impactos ambientais do Aterro Sanitário Municipal Leste de Aquiraz

Abstract

Municipal Solid Waste (MSW), when inadequately disposed, may cause several physical, biological, and socioeconomic impacts. With the increasing amount of waste generated, it is important to have an adequate management to minimise those impacts. The National Solid Waste Program (NSWP) establishes the guidelines for the management, one of them is that the appropriate disposal of the MSW must be carried out in Sanitary Landfills. Although the correct alternative, the Sanitary Landfills also cause environmental and social impacts, therefore needing environmental assessments so these impacts can be predicted, mitigated, or offset. One of the ways to assess environmental impacts is the Interaction Matrix, the accounts of the impactful activities of the undertaking and the way they affect each environmental component, therefore generating a visual structure that facilitates the analysis. The East Municipal Sanitary Landfill of Aquiraz (ASMLA) possesses an interaction matrix created in 1995; In this article, a new matrix was created to ASMLA so a comparison can be drawn between the two. The comparison showed some differences between them, positive, neutral and negative impacts.
