    Cenário das outorgas de lançamento de esgoto concedidas em Belém-Pa
    (Universidade Federal do Pará, 2017-11-09) RODRIGUES, Suzana Teixeira; PESSOA, Francisco Carlos Lira; http://lattes.cnpq.br/8031687016215046; BLANCO, Claudio José Cavalcante; http://lattes.cnpq.br/8319326553139808
    Conditions of effluent disposal grants authorized by the Department of Environment and Sustainability (SEMAS) of the Municipality of Belém PA, Brazil, between 2013 and 2016, are analyzed. Current study is divided into three parts: (1) collection of data retrieved from the Department; (2) preparation of a map showing effluent disposal grant sites at present; (3) number of non-computerized effluent discharges for each urban water basin in the municipality of Belém. Results showed that there are 24 effluent water disposal grants in the municipality of Belém: 62.5% are effluent disposal grants to residential housing estates; 25% are effluent disposal grants for industries; 12.5% are effluent disposal grants for other sectors, including hospitals and airport. The water resource with the greatest number of disposal sites is the Igarapé/Canal de Val-de-Cans, with five effluent disposal grant sites, followed by Igarapé São Joaquim/São Raimundo, with four effluent disposal grant sites. Very few effluents are treated at tertiary level, with disinfection prior to release in the water body. In fact, most Treatment Stations lie at the secondary level, since only organic matter is removed. However, enterprises with septic tanks and filters are still extant. Results also demonstrate that the urban water basin with the greatest unaccountable effluent discharge is the Bacia do Una, with 44,680.32 m³/day, followed by the Bacia do Outeiro, with 28,567.20 m³/day. Data are the SEMAS´s official numbers and they do not reveal the true conditions of the water bodies. In fact, there are several other effluent discharges which have not been regulated by the department and which contribute towards unbridled pollution caused by sheer lack of a comprehensive sewerage system in the municipality of Belém.

    Reciclagem como alternativa para a eficiência e sustentabilidade econômica do setor de resíduos sólidos urbanos no município de Belém-PA
    (Universidade Federal do Pará, 2018-05-28) SANJAD, Heitor Capela; PEREIRA, José Almir Rodrigues; http://lattes.cnpq.br/9918600634569244
    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 $ 8,256,759.16 and R $ 56,513,518.32, respectively, in the proposed scenarios. With the work it was possible to conclude that recycling is an excellent alternative to improve infrastructure and reduce expenses in the SUW sector of the municipality of Belém.
