RESUMO

This work is an approach to the development for sustentability in the sector of the Civil Construction, focusing the residues generated by the constructive activities and its use in the recycled aggregates production. As the production process in the construction industry is based on a lineal model is unviable, it degrades the middle-atmosphere and they contribute to the exhaustion of the natural resources. The recycling of the waste of the constructive activities for the Plants of Recycling constitutes an environmental alternative consolidated by several countries. With the implantation of recycling plants it becomes possible the minimization of the residues, transformed in raw material and beneficiaries for the production of recycled aggregates. Investigations were accomplished at located Plants of Recycling in the State of São Paulo through field research, observing the arrival of the residues in the plants, the production line, the generation of the recycled aggregates and its use in civil works; it was verified that the researched plants process own characteristics in function of their administrative aspects, of its infrastructure and of the operational equipments. Among the differential of the plants they stand out the plants, the equipments used in the recycling, the cooperative participation, the users of the recycled wastes and innovations in the administration of the development for sustentability in the Civil Construction. Datas were analysed individualy for each recycling plant and results were presented by categories , as well as, the individual characteristics and the seential aspects for each undertaking. Final considerations show the most important aspects for the success of the analysed plants that can give an orientation to up-to-date plants projects and to increase interests in the reuse of the residues and to start challenges to new construction materials
