Study of the economic and financial viability of recycling of constituents of construction and demolition residues

Abstract

ABSTRACT: The objective of this work was to evaluate the economic and financial feasibility of construction and demolition projects to carry out the recycling of concrete and ceramic fragments. For this, four economic scenarios were designed considering constructors responsible for the generation of different amounts of construction and demolition waste (RCD's), in which a mobile squeegee was used to recycle the material. The costs related to the acquisition, operation and maintenance of the crushing machine were compared to cash flows, with revenues from the use or sale of recycled material in the form of gravel No. 0, as well as the economy with litter bins. Subsequently, the profitability of the projects was evaluated by the capital recovery factor, the net present value and the internal rate of return. The higher the production of RCD’s, the greater the cost-benefit ratio of the purchase of the crushing machine and, due to the greater quantity of recycled crushed stone (which can be used in the production of sub-floor or commercialized) and the largest economy with a bucket of debris, the higher are the revenues acquired, the lower the return period of invested capital and the greater the financial profitability of the projected scenarios. Recycling RCD’s in addition to providing environmental benefits can be a financially attractive investment.
