Assessment of the composting of poultry carcasses by bin methods and aerated static piles

Abstract

It was evaluated the compostability of various waste properly mixed and the efficiency of different processes (aerated static piles and bin compost) in the elimination of microorganisms and time of composting. The experiments were built and monitored with the following compositions: bin method - coffee straw, poultry litter and poultry carcasses, ASP 01 - sugar cane bagasse, poultry litter and poultry carcasses; ASP 02 - sugar cane bagasse, poultry litter and ground poultry carcasses; ASP 03 - coffee straw, poultry litter and ground poultry carcasses. The parameters monitored during the process, were: temperature, C/N ratio, volatile solids (VS), pH and water content, besides Salmonella elimination and thermotolerants coliforms reduction were evaluated. The results obtained for the reduction of VS 20.87% (bin method), 25.31% (ASP 01), 28.86% (ASP 02) and 54.48% (ASP 03).
