RESUMO: O presente trabalho buscou avaliar a eficiencia do processo de compostagem por composteira para tratamento da carcaca de frango quanto a estabilizacao da materia orgânica e a eliminacao de microrganismos patogenicos, dando enfase ao procedimento adotado pelos criadores da Zona da Mata Norte de Minas Gerais. Os materiais utilizados no experimento foram cama de frango, palha de cafe e carcaca de frango. A montagem foi feita em camadas e, em proporcoes recomendadas pela literatura, sendo a adicao de agua correspondente a 20% da massa de carcacas de frango. Os parâmetros monitorados durante o processo, foram temperatura, relacao C/N, solidos volateis (SV), pH, capacidade de troca cationica (CTC) e conteudo de agua. Para avaliacao da eficiencia do processo foi avaliada a reducao de SV e o indice CTC/COT ? 1,7 (grau de estabilizacao da materia orgânica) e eliminacao de Salmonella e reducao de coliformes termotolerantes (higienizacao do composto). Apos 90 dias, os resultados se mostraram satisfatorios, tanto em termos de estabilizacao da materia orgânica, quanto da higienizacao do composto, que e a eliminacao de Salmonella e a reducao de coniformes termotolerantes a niveis satisfatorios. A reducao de SV e o indice CTC/COT foram, respectivamente, 22,05% e 5,75%. De acordo com estes resultados concluiu-se que o processo se mostrou satisfatorio no tratamento de carcacas de frango.  ABSTRACT: The aim of this work was evaluate the composting process by bin method for the treatment of poultry carcasses where as organic matter stabilization and pathogenic microorganism elimination, emphasizing the procedure adopted by poultry farmers of Zona da Mata Norte of Minas Gerais. The materials used in the experiment were coffee straw, poultry litter and poultry carcasses. The building was in layers, in proportion recommended by bibliography and it was added water corresponding the 20% of carcasses mass. The parameters monitored during the process were: temperature, C/N ratio, volatiles solids (VS), pH, cation-exchange capacity (CEC) and water content. For assessment of the efficiency of each process the reduction of VS and CEC/TOC index, which CEC/TOC ? 1,7 (stabilization grade of organic matter); the Salmonella elimination and thermotolerants coliforms reduction (sanitization of compost) were evaluated. After 90 days, the results were satisfactory, not only in the organic matter stabilization, but also in the compost sanitization, which is the absence of Salmonella and satisfactory reduction of thermotolerants coliforms. The reduction of VS and the CEC/TOC index were, respectively 22,05% and 5,75. According the results, it was concluded that the process showed satisfactory in the treatment of poultry carcasses.
