Proposta de gerenciamento de resíduos sólidos de empresa de mineração de calcário

Abstract

Mining contributes to technological advancement over time. New technologies are developed to meet the growing mineral extraction market. From this development, there is a greater efficiency in the production process and a considerable increase in the amount of raw material withdrawn from the environment, consequently there is also an increase in the amount of solid waste generated in the production process. The following study deals with the application of a tool called FMEA, which has the objective of quantifying and treating the data relevant to the limestone extraction and beneficiation process of a company from the city of Caçapava do Sul - RS - Brazil. An interesting application, able to guide and restructure operational procedures in order to generate the minimum of solid waste to be disposed of in landfills or to be disposed in the open. Every solid waste management process should have a guiding system as presented. It was possible to equalize the rationale of NBR 10.004 and to add a vision of mitigation of environmental impacts to the company, besides obtaining a satisfactory result with the use of the presented tool.
