Análise técnica para aquisição de equipamento de fragmentação primária de resíduos da construção civil em um canteiro de obras na cidade de Maringá/PR

Abstract

The objective of this work is to study the feasibility of the recycling Class A waste (recyclable with existing technology), and calculate the time to return the investment through the discounted payback technique. The study began by observing the disposal of Class A waste, mostly debris, at the construction site and an opportunity to add value to this, previously considered waste, in final product with market value. First, was carried out a research with theoretical reference and equipment available in the market. In the next stage, a building was chosen for study and in it, data were collected from the monthly volume of debris with the construction master, an interview was carried out ,and analyzes were carried out at the site to verify if it was possible to implement the proposed system. Finally, with the data obtained, the time of return was calculated (payback). The payback found was approximately one year and 128 days with an internal rate of return (IRR) of 28.89% and this data can be considered favorable, therefore an acceptable investment. However, as the building studied is independent and has its own regiment, it was understood that the proposal is not viable, because the equipment loses its usefulness when the work is finished.
