“…3). Cette élévation de la température est la conséquence directe de l'oxydation de la matière organique des substrats (Hassen et al, 2001 ;Ahn, 2009). Cette oxydation permet ainsi la libération de l'énergie contenue dans les liaisons chimiques des molécules constitutives (Ryckeboer, 2003).…”

This work is in the context of the management and recycling of solid urban waste. The evolution of the physicochemical and microbiological parameters during composting pilot scale household waste was studied. The maturity of the processes and the agronomic value of the finished product were examined. The results showed that the organic fraction of solid waste could be composted successfully in 60 days and revealing a vigorous microbial activity. The final compost has been satisfactory for its agricultural application. Phytotoxicity tests conducted on wheat and tomato crops, show that the incorporation of 25% culture support the compost allows a germination rate of up to 85% against 70% for the control for the variety of corn. In the case of tomatoes, we recorded a germination rate of about 67% against 58% for the control.

Le compost final a été satisfaisant pour son application agricole. Les essais de phytotoxicité menés sur des cultures de blé et de la tomate, révèlent que l'incorporation de 25% du compost au supports de culture permet un taux de germination allant jusqu'à 85 % contre 70 % pour le témoin pour la variété du blé. Dans le cas de la tomate, nous avons enregistré un taux de germination de l'ordre de 67 % contre 58 % pour le témoin.

“…Segundo Hassen et al (2001), a presença de coliformes é, de modo geral, utilizada como indicador da qualidade sanitária em amostras de solos e água. Em seu trabalho, os autores detectaram a presença de 2,5 x 10 7 UFC g -1 amostra seca no início do processo de compostagem de resíduos só-lidos municipais, diminuindo para 7,9 x 10 3 durante a fase termofílica.…”

RESUMOObjetivou-se avaliar o desempenho de quatro sistemas para compostagem de carcaça de aves pelo monitoramento diá-rio da temperatura, análise da presença ou ausência de Salmonella sp., contagem de coliformes totais (CT) e fecais (CF) e reciclagem de nutrientes. Os sistemas avaliados foram: Leira com aeração (LCA), Leira sem aeração (LSA), Composteira com aeração (CCA) e Composteira sem aeração (CSA). O processo de compostagem foi conduzido em dois estágios. No primeiro, as carcaças foram intercaladas com cama de aviário, palha e água. No segundo estágio, a massa de compostagem foi transferida para um pátio onde o material foi revolvido e umedecido semanalmente até a estabilização. Detectou-se a presença de Salmonella sp nos sistemas LSA e CSA ao final do primeiro estágio, desaparecendo após o segundo estágio. No composto, observou-se redução do número de CT e CF e dos teores de N e C, além de acréscimo dos demais nutrientes. Concluiu-se a favor da realização da compostagem em qualquer um dos sistemas avaliados e importante realizar um segundo estágio da compostagem, tanto para eliminação de patógenos como para obtenção de um composto com melhores características agronômicas.Palavras-chave: temperatura, Salmonella, coliformes totais e fecais, reciclagem de nutrientes Performance of four poultry carcasses composting systems ABSTRACTThe aim of present study was to evaluate the performance of four poultry carcasses composting systems through daily temperature monitoring, in the absence and presence of Salmonella sp., total (TC) and faecal coliforms (FC) number and nutrients recycling. The evaluated systems were: Piles with aeration (1), Piles without aeration (2), Composters with aeration (3) and Composters without aeration (4). The process was carried out in two stages. The first stage was performed by arranging the carcasses with straw and water. In the second stage the compostage mass was transferred to a composting area where the material was revolved and wetted weekly until stabilization. The presence of Salmonella sp in the systems 2 and 4 at the end of the first stage was detected disappearing after the second one. In the compost a reduction in the number of TC and FC and of N and C contents as well as an increase in the rest of nutrients by the end of second stage was observed. It may be concluded that it is possible to perform the poultry carcass composting in anyone of the evaluated systems and is important to perform a second stage in the composting process to eliminate pathogens as well as to obtain a compost with better agronomic characteristics.

“…[36][37][38] Similarly, windrow composting of spent broiler litter resulted in at least 6 log 10 reductions in numbers of total coliforms, fecal coliforms, E coli, and fecal Enterococcus spp. 39 Another study 40 of composting of municipal solid waste has revealed similar trends.…”
