%X High population growth and densities in urban areas and the consumerism present in modern societies have pronounced effect on the generation of organic waste, which may become an environmental problem. Aerobic composting is one of the best known alternatives to treating these wastes. This study aimed to evaluate the applicability of composting as an alternative to the disposal of organic wastes from aquatic macrophytes Eichhornia crassipes and Salvinia auriculata collected in the reservoir UHE Luis Eduardo Magalh es, Tocantins, Brazil and also produce an organic compound from different combinations of macrophytes, prunning residues and organic waste generated by the Campus of Palmas of UFT, TO. The study was conducted in an area of 80m2 in unprotected environment at the experimental station of the Campus of Palmas. The experiments were done as three replications in the dry season (from 18.09.2008 to 11.21.2008) and rainy season (from 03.09.2009 to 05.04.2009) and the parameters temperature, pH, total nitrogen and carbon, and organic matter were monitored along with counts of microorganisms. It was possible to produce compost from the combinations of organic wastes within 65 days of composting during the dry season and 55 days in the rainy season. The aquatic macrophytes resulted in a good raw material for composting, since there is not a destination for the excess plant materials removed by the cleaning process of the reservoir.
