Definição de alternativa economicamente viável para reciclagem de resíduos de construção e demolição de classe a do Município de Cruz das Almas - Bahia

Abstract

In civil construction, as in other areas of society, the issue of the importance of perpetuating the environment has gained prominence. It is common knowledge that civil construction transforms the world, and in this process, from obtaining the raw materials to delivering the final product, there is an infinite amount of damage caused to nature. Based on the fact that a large part of the volume of urban solid waste comes from civil construction, preventing it from being deposited in landfills will increase the useful life of these areas, reintroducing this material into construction processes is a notable alternative if, in addition to other justifications, itself receives financial relevance. Under this condition, alternatives were proposed for modeling a construction and demolition waste recycling plant, for real conditions in the municipality of Cruz das Almas in Bahia, based on processes consolidated in the literature. Some models have proven to be stimulating, but the one that shows the best cost/benefit ratio is the one that promotes indirect collection, uses statistical bases present in the literature to quantify the RCD generated and requires segregation carried out by the generator, in addition to producing at the end of the process aggregate capable of being reinserted into civil construction activities.
