Proposta de um biodigestor anaeróbio setanejo em um canil em Campo Mourão/PR: uma solução sustentável com potencial de geração de renda

Abstract

The significant increase in the canine population, combined with inadequate waste management practices, highlights the urgent need for solutions that minimize the environmental impacts associated with soil and water pollution. Despite growing awareness of the importance of these practices, there remains a gap in the development of accessible and effective technologies for treating this type of waste. The primary objective of this study was to propose the implementation of a rural anaerobic biodigester in a kennel located in Campo Mourão/PR, aimed not only at treating canine waste but also at generating biogas and biofertilizer. The adopted methodology included the biodigester's sizing, analysis of methane generation potential, and an economic evaluation that considered the costs and benefits associated with its operation. Results indicated that the biodigester installation could produce 648 liters of biogas annually, with a return on investment estimated at five years. Furthermore, the research demonstrated that this technology not only reduces greenhouse gas emissions but also provides an economically viable solution for managing canine waste. The implementation of the anaerobic biodigester serves as a sustainable and replicable alternative for managing waste generated by kennels, aligning with circular economy principles by transforming waste into valuable resources and promoting both financial and environmental sustainability.
