Item Acesso aberto (Open Access) Análise para implementação de usina para reciclagem de resíduos da construção civil em Tucuruí-Pa(Universidade Federal do Pará, 2018-05-25) SIQUEIRA, Rafaela Ribeiro; MACEDO, Alcebíades Negrão; http://lattes.cnpq.br/8313864897400179Civil Construction Waste (RCC), as they are known, is generated in construction, remodeling, repairs, excavation of land for civil works and demolitions. In this context, the work was carried out in the municipality of Tucuruí in the State of Pará, with the objective of evaluating the economic feasibility of implementing a RCC Recycling Plant. Research was carried out to diagnose the management of RCCs by the public authority of the city and it was verified that management does not take place efficiently. Thus, through the collection of information, it was possible to estimate the generation of RCC in Tucuruí, the daily generation is around 1.566,33 m3. Thus, to carry out the economic feasibility analysis, the annual gross revenue was determined, where the costs of implementation of the project and operation were calculated, and from the calculated net values, the cash flow from the Recycling Plant and the investment analysis method was calculated using the Net Present Value (NPV), Internal Rate of Return (IRR) Payback (PB) and the Profitability Index (IL) for the time horizon of 20 years, not considering the inflation. In order to define the Minimum Attractiveness Rate (TMA), a rate of 12% was adopted, since it is close to the SELIC rate for the year 2017, 12.25%. The results show that there is economic and financial feasibility in the implementation of this investment, thus, NPV R $ 1,148,946.06 positive, IRR 14%, PB will be completed in 4.2 years and IL 1.71, demonstrating the economic viability of the project. The estimation of three different scenarios was also done, with 5% increase in gross revenue, 5% increase in expenses and increase in TMA by 15%, thus concluding attractive results for the investment.
