Avaliação do potencial de uso de agregados reciclados na fabricação de paver por empresas de pré-moldado na cidade de Fortaleza, Ceará

Abstract

Civil construction is one of the oldest known activities, being considered of great importance to economic and social development. However, it is related to the high consumption of nonrenewable natural resources, in addition to generating large amounts of waste, resulting in an environmental impact. Therefore, actions are needed to face this problem. Brazil has the socalled national solid waste policy (PNRS), established by law and which determines how waste should be disposed of, encouraging recycling and sustainability. Therefore, the objective of this study was to evaluate the use of recycled aggregate for the manufacture of paver by companies belonging to the civil construction sector in the city of Fortaleza-CE. For this, a case study was carried out based on the application of previously formulated questionnaires to collect the necessary information. After obtaining these data, it was then possible to carry out an analysis of the general panorama of the use of recycled materials by the interviewed companies. It was found in results that 80% establishments do not have basic knowledge about the premises and necessary procedures regarding the classification, destination, and recycling of waste. The evaluated companies do not consider the use of recycled aggregate because they understand the viability of the manufacturing process as uncertain, requiring experimental studies to prove it.
