Abstract

This work presents a characterization study of solid wastes collected by the Municipality of Santa Mariana, PR. In this way the data collected in October 2017 from the municipal waste was obtained from the Municipality of Santa Mariana, Department of the Environment. From the data analysis found that the the Public Cleaning Service collected an average of 8.8 ± 4.5 ton/day of RSUs in the Municipality of Santa Mariana and that the largest amount of waste collected weekly is in the Vilas sector (χ2 = 4.7 ton/day). The gravimetric characterization indicated that of the RSUs collected approximately 33% are of organic materials, 37% of recyclables, 29% of wastes and about 1% of electronics. Furthermore it was found that there was a standard waste generation, with the Central and Industry sectors generating more recyclables (44% and 41%, respectively) and Villages more organic and tailings (40% and 32%, respectively).The results show that the knowledge of these characteristics is of paramount importance for the planning of urban solid waste management in Santa Mariana.
