Summary: Urban development is associated with the growing generation of Construction and Demolition
Waste (CDW). Despite being a technologically known process that generates environmental
benefits, the Processing of CDW and the production of Recycled Aggregate (RA) for its
extensive recycling present technical and economic barriers, which need to be clarified. From
an extensive bibliographical and documental review, the parameters porosity, water
absorption, density and strength were identified as those that are most changed with the
insertion of RA in the production of concrete, determining that its previous classification and
granulometric homogeneity of RA influence in the technical feasibility of its applications. On
the other hand, the operating costs with transporting RA and the interest rates applied in the
financing of this type of project severely influence the economic viability of CDW recycling
plants. In a second stage, a case study was carried out to analyze the effects and magnitudes of
intrinsic costs in the improvement and feasibility of a project. For this, data from Espírito
Santo/Brazil were used. Thus, it was possible to observe that even after analyzing the impacts
of interest on the project´s viability, the value for selling the RA and receiving the CDW can
be about 100% more significant. Finally, this work provides instruments that support
decision-making for the implementation of processing plants for construction and demolition
waste, in addition to encouraging the recycling of CDW.
