Estudo da desoneração dos serviços de limpeza urbana e destinação final dos resíduos sólidos da Cidade do Recife-PE

It is estimated that 1.3 billion tons of municipal solid waste are generated on Earth per year. By 2025, the planet inhabited by about eight billion people, of whom five billion will be concentrated in urban areas, the amount of waste generated can be duplicated. Between 2013 and 2014, Brazil increased by 2.88% in the generation of daily MSW, alarming number, since the areas for disposal of such waste are becoming increasingly scarce. The city of Recife-PE has the Urban Cleaning contract and Final Destination of solid waste as one of the most expensive. As a growing city and large, residents of Recife generate large amounts of waste, of which only a small part is recycled properly. About 1.31% of the recyclable portion of this waste is harnessed through the activities carried out by the city to perform the selective collection in the city. In this context, the waste must be treated and recovered by available and economically viable technological processes before the environmentally sound disposal. To achieve these goals, you can name three processes and reduction tools and treatment of solid waste: the Integrated and Sustainable Management of Solid Waste, recycling and selective collection. This research aimed to evaluate the current management model of selective collection and propose a possible exemption of urban cleaning services and disposal of municipal solid waste from the home collection through surveys conducted in Empresa de Manutencao e Limpeza Urbana - EMLURB in the recycling industries and cooperatives supported by the city. Finally, an estimate of economic valuation was presented for recyclable solid waste generated in the city with the subsequent organization of scenarios that showed a possible exemption of urban cleaning contract and disposal of waste through marketing estimates recyclable portion of waste generated by the population. In scenario 1, which depicts the current way in which the recyclable solid waste is managed, Recife presented a potential reduction of 17.54% of the costs of selective collection, equivalent to R$ 877,965.38. In Scenario 2, where the share of expected use of recyclable waste was 8%, it was observed that in 2036, the final year of the projection, the marketing of such wastes would bring the city revenue of R$ 25,248,195.14. In Scenario 3, with 15% success, the generated profit was 11.48% at the end of the period, generating an approximate income of R$ 47,340,365.88. Finally, in the 4th and last scenario, the profit expected in 2036 was 34.00%, since the marketing of such waste would generate a gain of R$ 123,084,951.29
