The Diagnosis of Solid Residues Produced in Free Trade Shows: A Case Study

The high production of solid waste in urban fairs despite being a fact known and visible to anyone, is little studied in gravimetric terms. In this sense, this article aims to identify the gravimetric characterization of the Modern Banana Fair, located in the central area of Manaus, in the Amazon region, to characterize the types of waste generated and the environmental impacts. In methodological terms, the following steps were carried out: Bibliographical research, Data collection, Composition analysis based on the Brazilian Regulatory Standards: NBR-10007 - waste sampling: procedure, and NBR-13463 referring to solid waste collection: classification. The results allow to affirm that the predominant gravimetric fraction was that of organic matter (86%), coherent for a large fair, as studied, followed by paper/cardboard (6%) and plastic (4%). These data are in line with the activities of generating such waste, called: retail and wholesale marketing of products (fruits, legumes and vegetables). The major concern becomes the destination of these wastes, since they currently go to common public collection, and are destined to the sanitary landfill of the city. In addition, according to the results of this research, the residues generated have the potential to generate energy (bio gas), which can be obtained through stimulated decomposition of the material. The possibility of generating energy from the waste is still neglected and not exploited by the region.
