Sertanejo biodigester: solid waste management in a kennel in Campo Mourão, Paraná, Brazil

The objective was to propose the implementation of an anaerobic Sertanejo biodigester in a transient pet center, aiming at treating canine waste with biogas and biofertilizer generation. The methodology adopted involved the sizing of the biodigester, the analysis of the biogas generation potential, and an economic evaluation considering the costs and benefits associated with its operation. The results indicated that installing the biodigester could produce 648 liters of biogas per year, with a return on investment in an estimated period of five years. In addition, the research demonstrated that opting to use the rural biodigester model provides a viable economic solution for waste management at the site. Implementing the anaerobic biodigester is a sustainable and replicable alternative for waste management, aligning with the principles of the circular economy by transforming waste into valuable resources and promoting both financial and environmental sustainability.
