Gravimetric Characterization of Solid Waste in the Dump of the Municipality of Coari - Amazonas, Brazil

Objective: To estimate the gravimetric characterization of solid waste in the waste dump in the municipality of Coari, located in the state of Amazonas, in the region of the Middle Solimões, Brazil, and to evaluate the implications for sustainable management and management. Theoretical Reference: The main public policy bases related to solid waste treatment, from generation to final destination, were contextualized, as well as the scenarios regarding gravimetric composition, as well as the references to support a resolving horizon for materials of a recyclable nature. Method: This study addresses quantitative and qualitative analysis of the collected samples of solid waste destined to the landfill of the municipality of Coari - Amazonas, in accordance with the steps required by NBR 10.007/2004 and tabulation in Microsoft Excel. Results and conclusion: The results indicate that the majority is composed of organic material, followed by plastics and paper/cardboard, among other smaller fractions: glass, metals, wood, pointing to the need for the implementation of urgent recycling and composting practices, even if the municipality does not have an environmentally adequate destination. Implications of the research: In Brazil, even with the public policies already implanted, the great majority of the municipalities have not yet propitiated the extinction of their garbage dumps or have some irregular form as to the final destination of their solid residues. The gravimetric composition is one of the important tools for analyzing the composition of materials taken to the final destination, which is absent in many municipalities. Originality/value: Knowledge of the composition of the fractions of the solid waste generated is fundamental for guiding strategic actions and planning related to management and management, aligned with public policies that direct the practices of utilization from the generating source to the final destination, in order to avoid expansion or mitigate environmental impacts.
