Eficiência energética na indústria: estudo de caso em uma empresa metalúrgica

Abstract

The increase in energy prices and the pressure to reduce CO2 emissions, coupled with the concern for sustainability, have led to the study of energy efficiency and its consequent reduction in energy waste, optimization of its production and the promotion of rational and efficient use of existing energy. The present work, through a bibliographical review, has as main objective to carry out an energy efficiency study in a metallurgical company, that has high costs and energy demands. A study on energy consumption in the national industry and the main sources of energy was done as a way to assess how best to achieve energy efficiency in the industry, which revealed that the sector has a great potential to reduce energy electricity consumption. It also addressed the main opportunities to be realized in the industry as a form of energy saving and the barriers found for the advance of energy efficiency in the sector. A case study is presented using the Energy Management program aligned with the principles of the PDCA in order to show the impact that occurs when energy efficiency is made in the industry and how important it is that all employees of the company engage in the program, to achieve good results. It was possible to observe that simple measures involving personal behavior bring satisfactory results in the reduction of electric energy consumption. It is important that the owner's sense is raised in the employees to change habits and instill them in the constant search for a production process more energy-efficient as well as economically.
