Gestão de resíduos de poda: estudo de caso da Fundação Parques e Jardins do Município do Rio de Janeiro.

Abstract

It´s agreeded that the urban development is responsable for the enviromental disequilibrium that predominates in the most populous cities, where the administration of residues becomes a great challenge. This study was made in order to develop a model of urban residues pruning trees management in public places, intending to use of the pruned material which is considered in good conditions. It would also minimize the residues deposit in sanitary landfills. For this, a differentiated model was developed through legal, managemental, tecnological, and economical point of view, which could serve as a reserch base and benefit the enviroment. The Conservation Unit which belongs to the Rio De Janeiro City hall Parks and Gardens Foundation, that is located in Taquara, was analized in the case study. The tree species that produce greater volume of pruning had been selected in this section so that that it was possible the economic and ecological exploitation. It was concluded that it is unviable for the Gardens Foundation to segregate the pruning residues it self, and that, the residues could be transferred directly to it´s final destination, in closing of activities phase, without extra cost. A special appreciation of the Solid Waste Treatment Center located in Gericinó was done, because of the fact that it is a great receiver for residues produced in the area in evidence handling operations. It was elaborated a proposal of creation of a Green Work in the landfill disactivated areas, as a complementary form to the area filled with earth revitalizating process, after the activity end. This action would comtemplate the regions with a urban forest, where all the pruning residues products would be absorbed. There´s also a operational use probability for the landfill workers in the organic composite attainment stages, death covering and landscaping equipament, among others.
