Coprocessamento de resíduos sólidos aplicado na indústria cimenteira: uma prática sustentável

Abstract

Given the worsening climate crisis and the need for more efficient and sustainable industrial practices, co-processing stands out as an alternative capable of generating environmental and economic benefits. This process consists of the partial replacement of raw materials and fossil fuels with solid waste that has a calorific value and composition suitable for the operation of clinker kilns used in cement production. In this way, waste that could receive inadequate disposal is reused as industrial inputs, reducing environmental impacts and increasing productive efficiency. The use of waste in co-processing is rigorously monitored by legislation that regulates classification, associated risk, and correct disposal methods, ensuring that the entire process occurs within governmental parameters. Based on this, the Undergraduate Final Project aims to investigate the co-processing carried out by an industry that treats solid waste using this technique. The research, characterized as applied and descriptive, seeks to relate theoretical knowledge with the practice observed during the technical visit, in addition to analyzing the environmental impacts resulting from the company's operations. The state-of-the-art report compiles information on the co-processing of solid waste in clinker kilns, regulatory standards, and the National Solid Waste Policy. It also addresses socio-environmental aspects, technology, quality control procedures, and the technical-scientific production related to the topic. The results indicate that the model adopted by industry presents itself as a viable, safe technological solution aligned with the demands of economic development combined with environmental responsibility.
