Gravimetry is an important information in the management of solid waste, as it assists in environmental monitoring, in understanding the process of decomposition of waste and in estimating the useful life of materials for recycling, data that are also crucial for the preparation of municipal solid waste plans. Thus, this article aimed to characterize the solid waste produced in the city of Soure, in Pará, to contribute to its solid waste management. The gravimetric characterization defined in NBR 10,004 of 2004 was used. It is noted, after gravimetry, that the largest generation of residues is concentrated in the tailings and organic matter materials, which represent 86.6% of a sample of 91.5 kg. The largest amount of recyclable material collected was 4.16 kg of colored PP film and the smallest of Tetra Pack material, with 0.21 kg. The monthly gain from recycling for each collector would be an average of R50.00and,therefore,itisessentialthatthegovernmentintervenesthroughthecooperative,supportingservicesandreducingcosts.Eventhoughthemunicipalityhaspotentialforrecycling,thereisstillweaknessinpublicpoliciesforwastemanagement,mainlyintheadoptionofmunicipalguidelinesthatencourageitasanalternativefortheeconomyandtheenvironment.Keywords:SolidWaste,Recycling,Management.Agravimetriaconstituiumainformac\ca~oimportantenagesta~odosresıˊduossoˊlidos,poisauxilianomonitoramentoambiental,nacompreensa~odoprocessodedecomposic\ca~odosresıˊduosenaestimativadavidauˊtildemateriaisparareciclagem,dadosessestambeˊmcruciaisparaelaborac\ca~odosplanosderesıˊduossoˊlidosmunicipais.Assim,esteartigoobjetivoucaracterizarosresıˊduossoˊlidosproduzidosnacidadedeSoure,noParaˊ,paracontribuirnasuagesta~oderesıˊduossoˊlidos.Utilizou−seacaracterizac\ca~ogravimeˊtricadefinidanaNBR10.004de2004.Nota−se,apoˊsagravimetria,queamaiorgerac\ca~oderesıˊduosseconcentranosmateriaisRejeitoseMateˊriaOrga^nica,querepresentam86,650,00 e, portanto, sendo essencial que o poder público intervisse pela cooperativa, apoiando os serviços e reduzindo os custos. Mesmo o município apresentando potencial para a reciclagem, existe ainda fragilidade nas políticas públicas para o gerenciamento dos resíduos, principalmente na adoção de diretrizes municipais que a incentivem como uma alternativa para a economia e o meio ambiente.Palavras-chave: Resíduos Sólidos, Reciclagem, Gerenciamento
In the research, classified as descriptive and exploratory, the technical efficiency
and economic sustainability of the solid urban waste (SUW) sector of the city of
Belém - PA was evaluated. The research divided into three stages had in its first
phase the execution of the legal, operational and financial diagnosis of the
municipality. Then, in the second stage, scenarios were established to recycle 10%,
25% and 50% of MSW generated in the municipality in the year 2017. In the last
stage, the sales prices of recyclables were determined and the economic prospects
were estimated in the proposed scenarios, besides the evaluation of the financial
benefit that the selective collection can bring the public finances. The generation of
340,405.39 tons SUW was verified in the city of Belém, as well as the existing need
to update the laws, elaboration of the planning tools and reformulation of the forms
of collection of the services provided in the sector. It was also observed that the
implementation of recycling of 10%, 25% and 50% of the total RSU mass generated
in 2017 would reduce operating expenses by R 11,302,703.66,R 28,256,759.16
