There are a large number of wastes that are not used in marble, like remains of marbles and granites and that are deposited in vacant lots without any concern, causing environmental liabilities because they are incorrectly deposited in the environment in addition to a waste of the raw material, causing financial loss, wasting this material that can be used in construction. Concrete plant factories are a great solution for the use of these wastes, as they pass through a recycling plant and can replace the small aggregates in the production of concrete artifacts, such as pavers, blocks, tiles among many other types of artifacts. In this way, it was sought to make research on the reuse of this residue by making an implantation of a factory of concrete artifacts with structure to transform these residues into small aggregates and thus incorporating them in the production of concrete pieces, a comparative was also made with a factory where the marble wastes were not used and did not even have the structure to use them. It was verified through the economic feasibility study and the calculation of the IRR (internal rate of return) that it is feasible to use marble residues in the manufacture of these artifacts and even with a cost of implantation greater than that of a conventional plant in a few years the factory with structure for reuse of marble waste becomes more profitable.
