Dog Waste in Biogas Production

Abstract

In Brazil, there is an increase in the number of pets, among which dogs are the most sought after. The increase in the number of pets also contributes to the increase in waste generation. The anaerobic biodigestion of these wastes is an alternative for obtaining biogas and environmental protection. Adequate environmental management and established guidelines for the disposal of animal waste are necessary for sustainable development and improved quality of life. The objective of this work was to carry out the anaerobic codigestion of mixed breed dog waste (SRD) with cattle waste, in batch biodigesters to obtain biogas. After 7 days of operation of the biodigesters, biogas production was observed, but this subsequently ceased, indicating some inhibition that needs to be studied in future work.
