Análise da viabilidade da utilização de resíduos sólidos orgânicos para a produção de energia elétrica em residências de um condomínio horizontal

Abstract

Due to the large development of the cities, one of the current challenges is the management of solid waste, since the excessive production of this kind of waste has become a real concern in the urban centers, once the majority of the sites used for an adequate disposal of this material are saturated. In this context, sustainable development has become one of the major global challenges, so that urban societies now require technological alternatives in the final disposal of this waste that are less impactful to the environment (so-called "green technologies"). Thus, the present work aimed to conduct a study to assess the feasibility of the implementation of a energetically sustainable horizontal condominium. The theoretical proposal was based on the utilization of biomass coming from organic matter produced by local condominium members as raw material for the electricity generation process. Based on the structuring of the organic solid waste molecule was estimated the lower heating value (LHV) of the sample and the result was compared with the values found in the literature. In addition, it was also performed an energetic analysis of the boiler and the turbine, estimating the amount of energy generated in the process. Finally, a preliminary analysis of the financial viability were conducted. The analyzes showed that the biomass from the sample of organic solid waste can be successfully used in the generation of electric energy, supplying, in part, the power consumption of the common area of the horizontal condominium. Although not completely supply the energy demands of the common area (since the power consumption is high), the use of biomass from organic solid waste would generate real savings in energy expenses and but also reduces un amount of waste going to landfill and therefore helping to preserve fare Environment.
