Revisão bibliográfica sobre a gestão e reutilização do óleo lubrificante industrial visando sua posterior aplicação em elementos externos das máquinas-ferramentas

Abstract

Lubricating oils are of essential importance for industrial operations in the most varied equipment, however, the fact that it is not a fully consumed resource during its useful life creates responsibilities for organizations with their destination after the use, as it is a harmful product to the environment. In addition, it is a noble compound, making its recovery relevant. Starting from this scenario, the present work seeks to analyze physical recycling processes that can be applied in an used industrial lubricating oil model aiming to reuse the product in the lubrication and protection of the external elements of the machine tools. Because it is a lubricant that is not exposed to critical working conditions and frequent reuse, the study proposes an appropriate management that aims to recover the compound for proper use, seeking to reduce the costs of companies with demands for lubricants, optimize logistics, avoid environmental impacts with improper disposal and reduce the spaces occupied with containers of oils used by the laboratory until the collection period, which is not recurrent depending on the region. Two physical recycling processes were introduced, that of sedimentation and filtration, which do not alter the properties of the product and any company can practice it because they are not complex methods. The study showed a relevant disposition of these techniques for the due attribution and future application of the recovered compound as a protection to the external elements of the equipment, bringing economic and logistical benefits. Although Brazil has the re- refining process as the basis for the final destination of the used lubricating oil, the regional location of the companies with the agents responsible for the collection ends up being impacted by the product management and demonstrates that accessible recycling processes may be relevant in any application.
