Abstract (English): The biofertilizer segment stabilized in anaerobic digesters offers a promising solution for reducing reliance on imported products. However, the development of this sector is largely constrained by logistical challenges, as well as the cost and feasibility of processing, transporting, and distributing organic fertilizers. To address these issues, this research presents a comprehensive thermoeconomic study of four scenarios applied in a rural microgeneration power plant in Toledo, Paraná state, Brazil. The main objectives were to determine the cost of the primary products, evaluate the system's potential for energy self-sufficiency, and assess its economic viability. These findings would help amortize the costs associated with installing and operating the technology while adding greater value to its by-products. In the thermodynamic analysis, the potential for electricity generation from swine residues was evaluated. The economic analysis used the net present value, internal rate of return, payback period, and levelized costs of both energy and biofertilizer. By comparing the energy consumption required to fertigate 1 m³ of swine manure with its electricity generation potential, the system could achieve energy self-sufficiency. Moreover, the economic indicators of the scenarios demonstrate their viability, driven by the sale of electricity, transportation services, and biofertilizers. [ABSTRACT FROM AUTHOR]
Abstract (Portuguese): O segmento de biofertilizantes estabilizado em biodigestores anaeróbios oferece uma solução promissora para reduzir a dependência de produtos importados. Um dos principais desafios para o desenvolvimento desse setor é a logística, o custo e a viabilidade do tratamento, transporte e distribuição desses fertilizantes orgânicos. Para contribuir com a redução dessas dificuldades, esta pesquisa propôs um estudo termoeconômico abrangente de quatro cenários aplicados em uma usina de microgeração rural, localizada em Toledo, Paraná, Brasil. Portanto, ao considerar esses cenários, o objetivo foi obter o custo dos principais produtos. Isso incluiu identificar se o sistema atingiu a autossuficiência energética e se essa implementação foi economicamente viável, contribuindo para a amortização dos custos associados à instalação e operação desta tecnologia, ao passo que agrega maior valor aos seus subprodutos. Na análise termodinâmica, foi avaliado o potencial de geração de eletricidade a partir de resíduos suínos. A análise econômica foi determinada utilizando o valor presente líquido, a taxa interna de retorno, o período de retorno, bem como o custo nivelado de energia e biofertilizante. O consumo de energia necessário para fertirrigar 1 m³ de esterco suíno, quando comparado ao potencial de geração de eletricidade deste esterco, poderá permitir que o sistema alcance autossuficiência energética. Os indicadores econômicos dos cenários considerados revelaram que são economicamente viáveis devido à venda de toda a energia elétrica, serviços de transporte e vendas de biofertilizantes.
