Proposta de um checklist para o acompanhamento das ações de melhoria ambiental em uma empresa do setor metalmecânico

Abstract

ISO 14001 is an international standard that establishes guidelines for an Environmental Management System (EMS), aiming at the continuous improvement of the environmental performance of organizations. For the metalworking sector, which faces significant challenges in terms of environmental impact due to the intense consumption of resources and generation of waste, adhering to the standard can represent an important step towards sustainability. One of the main challenges faced by companies is the high initial investment required to update processes and technologies, in addition to the need for training and capacity building of employees. This work presents a proposed checklist for monitoring environmental improvement actions in a company in the metalworking sector. The study was developed in an aluminum processing industry, analyzing the sheet reslicing process, a stage in which operational and maintenance factors that directly impacted lubricant oil consumption and premature wear of reslicing machine components were observed. Among the main issues identified, failures in the automatic lubrication system, in the coupling of the cutting disc, and excessive wear of the blades stood out, reducing the suction efficiency of the trimming and causing blockages in the exhaust system. To mitigate these problems and meet the principles of continuous improvement proposed by ISO 14001, a maintenance checklist and a systematized routine for cleaning and verifying the trimming machines were implemented. After implementing the preventive actions, a significant reduction in annual lubricant oil consumption of 17% was observed. The results demonstrate that adopting practices aligned with ISO 14001 contributes not only to reducing environmental impacts but also to increasing operational efficiency and consolidating a culture of industrial sustainability. Thus, the study shows that the integration between environmental management and preventive maintenance is fundamental for the continuous improvement of processes in the metalworking sector
