Previous issue date: 2016-07-28 / O modelo de produ??o observado na ind?stria da constru??o civil utiliza em boa parte recursos naturais n?o renov?veis e ? respons?vel pela gera??o de uma grande quantidade de res?duos. Uma das formas de amenizar os impactos desses res?duos ? a reciclagem. Diante deste cen?rio, o objetivo deste trabalho ? propor a cria??o de uma usina de reciclagem de Res?duos da Constru??o Civil na perspectiva da simbiose industrial, avaliando a sua viabilidade econ?mica e ambiental. A pesquisa ? um Estudo de caso de car?ter explorat?rio, de natureza aplicada, com uma abordagem quanti-qualitativa. Um question?rio estruturado foi aplicado junto ?s empresas da constru??o civil da grande Natal, cadastradas no SINDUSCON-RN, com o objetivo de conhecer a quantidade m?dia de res?duos gerada pelas construtoras, o destino dado aos res?duos e se h? separa??o dos res?duos na obra antes da destina??o. Com isso foi poss?vel estimar o tamanho da usina e seu volume de produ??o, para, assim, dimensionar os impactos ambientais envolvidos e estimar os custos e despesas, fatores essenciais para realiza??o das an?lises de viabilidade. Utilizou-se o Estudo de Impacto Ambiental (EIA) para a avalia??o ambiental e os m?todos de Valor Presente L?quido (VPL), Taxa Interna de Retorno (TIR) e payback para a realiza??o da avalia??o econ?mica. O trabalho concluiu que a implanta??o da usina de reciclagem de res?duos da constru??o civil na regi?o metropolitana de Natal ? vi?vel tanto ambiental quanto economicamente, bem como a organiza??o de forma simbi?tica das empresas ? vista de forma positiva no sentido de incentivar a separa??o dos res?duos na obra e, consequentemente, melhorar a qualidade do agregado reciclado produzido. Al?m disso, o reaproveitamento de res?duos pelas pr?prias construtoras reduz a extra??o de recursos naturais n?o renov?veis e a gera??o de novos res?duos, contribuindo para a diminui??o do impacto ambiental gerado por este setor. / The production model observed in the construction industry uses largely non-renewable natural resources and is responsible for generating a large number of waste. One way to mitigate the impacts of this waste is recycling. In this scenario, the objective of this study is to propose the creation of a construction waste recycling plant from the perspective of industrial symbiosis, assessing their economic and environmental viability. The research is an exploratory case study of applied nature, with a quantitative and qualitative approach. A structured questionnaire was administered with the companies of civil construction of the great Natal registered in SINDUSCON-RN, in order to know the average amount of waste generated by construction companies, the destination of the waste and if there is separation of waste in the work before allocation. Thus, it was possible to estimate the size of the plant and its production volume, to thereby scale the environmental impacts involved and estimate the costs and expenses, essential factors for carrying out feasibility studies. We used the Environmental Impact Assessment (EIA) for environmental assessment and methods of Net Present Value (NPV), Internal Rate of Return (IRR) and payback for the realization of economic evaluation. The study concluded that the implementation of the construction waste recycling plant in the metropolitan region of Natal is viable environment as much as economically, as well as the organization symbiotically of companies is seen in a positive way to encourage the separation of waste at work and, consequently, improve the quality of the recycled aggregate produced. In addition, the reuse of waste by own construction companies reduces the extraction of non-renewable natural resources and the generation of new waste, contributing to the reduction of the environmental impact generated by this sector.
