Biodigestão anaeróbia, compostagem e vermicompostagem a partir da fração orgânica de lixo urbano.

Abstract

Was utilized municipal solid waste colected at the Composting Plant from the municipal district of São José do Rio Preto- SP. The chemical characteristics of the compost and vermicompost were analysed. The results showed that there are no differences in the chemical concentration of the compost and vermicompost when compared with the raw municipal waste, however the great volume reduction and stabilization of the organic material must be considered. With regard to the anaerobic digestion, the biogas production indicated the energetical potential of municipal waste, which was found to be 0,1034 - 0,1395 m3 /kg of raw municipal waste.
