COMPOSI??O GRAVIMéTRICA DOS RESíDUOS SóLIDOS URBANOS DOS MUNICíPIOS ALAGOANOS DE INHAPI, DELMIRO GOUVEIA E PIRANHAS

摘要

This article presents a study about the composition gravimetric of the Urbans Solid Waste (SWU) generated in the towns of: Inhapi, Delmiro Gouveia and Piranhas, members of the regional consortium of solid wastes from the “AlagoanoSert?o”, it shows the knowledge of the percents of the fractions of materials that make the SWU, furthermore, the values for the specific weight o SWU from the cities were obtained, Being this information of great significance for optimization of the urban cleaning systems of the municipalities and implantation of selective collection system. For this study we used the quartering method. The SWU used to carry out the gravimetric composition were from convetional collection, that covering household nacomercial wastes. For the separation of waste fractions, it was considered the sales Market for recycling, reported by collectors presente in each dumpsite and is also made posible the diagnosis of these areas. The results of the gravimetric composition study indicate that the average approximate of organic residues are 58%; 30% of residues are enable of the recycling; and 12% represent the tailings.
