Análise multimétodo de percepções de agentes intervenientes na pesquisa e no gerenciamento de agregados reciclados de resíduos da construção civil

Abstract

Waste management in civil construction has limitations both in the private initiative as in the public sector. This happens in construction sites and recycling plants, and when reusing these residues to replace natural aggregates to produce construction materials. This study aims at identifying the elements preventing the waste recycling sector in civil construction from developing, as well as using the obtained results to offer recommendations to support the use of recycled aggregates in the Civil Construction Industry. In order to identify these elements, the perception of the intervening agents in management and research processes was surveyed: (a) professionals of nine construction sites in the municipality of Vitoria (Espírito Santo, Brazil); (b) researchers at state, national and international level; and (c) nine managers of recycling plants located in the States of Minas Gerais and São Paulo, Brazil. For this purpose, multi-method study was employed, which enables combining qualitative and quantitative approaches, comprising bibliographical research, data collection research, and case studies. The following instruments were analyzed for data collection: questionnaire, semi-structured interview, direct observation, and audiovisual records. Analysis of intervening agents’ perception showed that merchandizing, technological, organizational, cultural and environmental elements influence the waste recycling sector in civil construction. Based on this, a set of recommendations regarding these elements were prepared in order to be used by the intervening agents.
