The aim of this study was to speed up the composting process of municipal solid wastes, piles of material were inoculated with a mixed of endogenous microorganism. The bacteria identified were Bacillus subtillis and Pseudomonas fluorescens and one fungus, Aspergillus fumigatus. An inoculant was prepared in a concentration of 1x107 UFC/ml for each microorganism and was applied through aspersion, 2 L m-3. The following parameters were evaluated: Physical aspect, temperature, moisture content, pH,...
The aim of this study was to speed up the composting process of municipal solid wastes, piles of material were inoculated with a mixed of endogenous microorganism. The bacteria identified were Bacillus subtillis and Pseudomonas fluorescens and one fungus, Aspergillus fumigatus. An inoculant was prepared in a concentration of 1x107 UFC/ml for each microorganism and was applied through aspersion, 2 L m-3. The following parameters were evaluated: Physical aspect, temperature, moisture content, pH, C:N ratio, organic matter, electric conductivity and cation exchange capacity. The results showed that inoculated piles reached the stability and maturity, four weeks earlier than the control pile without inoculation. These results suggested that the inoculant was useful to accelerate the composting process in the urban wastes.
