Abstract

Composting is a process of bio-oxidation by a group of microorganisms and have as final result, stabilized organic matter. Amongst manures of animals, canine faeces are less used in composting processes, due to contaminations that could be a risk to the use of the final compound. Currently in Brazil there are over than 52 millions that correspond of an average of 1.8 dogs per household with this animal, related with that amount 41% of them are located in urban areas, indicating the need to develop alternatives for the generated solid waste disposal. The current study proposed to survey a possible destination for dog faeces as home composting, through the study of aging and contamination of compounds. The composting procedure was carried out in 3 buckets of 60 liter drilled in the side cover and containing: (1) 8 kg of household organic waste; (2) 1 kg of cow dung and 7 kg of organic domestic waste and (3) 1 kg of dog faeces and 7 kg of organic household waste. Where it could be observed that the addition of dog faeces did not affect the maturation process of the compounds. The assay of pathogens after 11-weeks of maturation it was detected the presence of coliform thermotolerant in all the compounds. The presence of Salmonella and helminth eggs was not observed in any of the samples. This study demonstrated that the use of dog faeces in home composting small-scale systems is a feasable alternative for the treatment of this waste at the place of its origin.

Key Words: compost, dog faeces. maturation compounds, organic matter.
