Resíduos da construção civil no município de Palmas - Tocantins: proposição de um modelo de boas práticas de manejo

Abstract

The construction industry has a significant contribution to the countries’ economy development, especially if considered the created jobs amount and the direct influence across the sectors that produce raw materials, equipment and services for use in its production process. In spite of this major highlight of Brazilian civil construction industry in the national economy, the sector is large consumer of natural resources, since the construction uses building materials in large quantity and variety , most often, for lack of planning, are wasted and turned into Construction Waste (CW) The progressive growth of the CW has been in conjunction with an increase in population, and bring with them environmental problems arising from construction growth that in order to attend the expectations of society go hand in hand with this development. the city of Palmas/TO in the past years has experienced an accelerated process of verticalization, accompanied by the generation of a large amount of CW. Regarding to the provisions of this waste in the city and the impacts they cause, this research proposed to diagnose the current situation, based on a theoretical framework of good practices and managing, and classification and quantification of CW generated for a period of one year. This information supported the development of a management guide based on best management and handling practices. The research method is characterized as a qualitative approach, with applied nature, exploratory and descriptive objectives, being used as a working method, bibliographical, documentary research and case study. Data were collected through the application of open questionnaires and interviews with pre-defined script. The main findings are: the lack of supervision and inefficiency of the municipal government; and the lack of environmentally proper management for construction companies, preventing them from having the financial gains from the reuse and recycling of CW. Recommendations for future studies are: the investigation of the effectiveness of ISO 9001 and PBQP-H certifications in construction companies, especially in the city of Palmas; the viability of the technical and environmental point of view of the adoption of the proposed the best management guide, in order to prove its effectiveness as the management of CW, and finally, the application of theoretical framework on field studies.
