Gerenciamento de resíduos sólidos de construção civil, em São Luís-MA

Abstract

In a construction project the production of waste is an almost inevitable effect. A fact that proves this, is that currently more than half of urban solid waste is derived from construction. At the same time, we have a relatively comprehensive legislation, which guides civil construction precisely in an attempt to induce better management of these wastes. However, this legislation is often not enforced, either because of ignorance or because of the negligence of those responsible. In São Luís/Maranhão, more specifically, the management of solid construction waste is still well behind schedule. Reuse and recycling are almost nonexistent practices, and builders often appeal almost always to landfill dumping. However, the number of landfills available for receiving waste is steadily decreasing. In São Luís itself there is no more landfill suitable for the reception and treatment of the same, forcing the builders to effect the eviction outside the city. This makes evident the need for a better improvement of waste management techniques in the capital of Maranhão. This work aimed at understanding and analyzing the situation of the management of these wastes in São Luis. Field surveys were carried out with the construction companies in progress, and the techniques and procedures for waste management used and not used by each one were observed. It is verified that the solid waste management of civil construction in São Luís as a whole, still lacks evolution, especially in the aspect of its planning in general for the work
