Energy efficiency enhancement in metalworking processes through iso 50001-based management systems

Abstract

The study explores the implementation of the ISO 50001 standard as an alternative energy management system for the metalworking industry, within the framework of the United Nations' sustainable development goals (SDGs). The main purpose of the research is to enhance the energy efficiency of a metalworking company, contributing both to environmental sustainability and the reduction of operational costs. The primary objective is to identify and apply energy management practices that optimize energy consumption in the plant. This is achieved through the characterization of electrical equipment used in the experimental facility and the analysis of its energy usage. A baseline and a target line were established to measure progress in energy efficiency, evaluating key indicators such as the consumption index and electricity consumption trends. Additionally, the study estimated the critical production point, the critical production rate, and the potential energy savings. The main findings reveal that the company’s lathes consume approximately 1.4 MWh per month on average, accounting for 80% of the total monthly energy consumption during the study period. It was also determined that the critical production parameter is 25.72 units per hour, which could lead to an estimated 7.26% reduction in current energy consumption. The study concludes that implementing recommended energy management practices can significantly improve production efficiency and enhance the company’s financial performance, highlighting ISO 50001 as a key tool for achieving these goals.
