Solução sustentável do coprocessamento de revestimento gastos de cubas na indústria do cimento.

Abstract

Currently, companies are dedicated to adopting new measures of environmental control and management, caring about who will be affected and how to avoid it, given that environmental pollution can lead to irreversible cases. Spent Potlining (SPL) is a waste generated in the aluminum industry, posing a significant environmental problem for this sector. In this context, the study aims to analyze how the treatment of SPL can become efficient through coprocessing in cement plants, preventing environmental damage. Specifically, it seeks to describe how coprocessing contributes to the non-emission of pollutants from SPL during the cement manufacturing process and investigate how the destruction of cyanide compounds contained in the carbonaceous fraction makes SPL a non-hazardous waste. This research is classified as a case study with a qualitative approach, descriptive and exploratory in nature. Based on the collected data, it was observed that coprocessing presents several contributions to environmental sustainability by incorporating SPL waste into the cement manufacturing process, reducing the extraction of virgin raw materials, minimizing the amount of waste sent to landfills, and decreasing greenhouse gas emissions. Emphasizing the importance of complying with environmental regulations and standards, following operational safety procedures, and taking the necessary measures to prevent environmental contamination and protect the involved employees. Additionally, it was possible to identify that coprocessing provides benefits and profitability for the cement industry by reducing production costs and contributing to the optimization of available resources through the use of alternative fuel.
