Desperdícios processuais e impactos ambientais de uma linha de recapagem de pneus sob a perspectiva do Lean e Green manufacturing

Abstract

The new ways of producing have demanded more attention to the aspects related to sustainability. Productivity is no longer a single objective and has become a necessity allied with sustainable practices, prioritizing a cleaner production. Within this context, the present work aimed to analyze the production process of a road tire retreading line under the Lean and Green Manufacturing perspective, in order to investigate the waste and environmental impacts present in the processes, as well as the relationship between the philosophies in reducing these problems. To this end, an analysis of the developed activities was carried out through visits, access to documents, semi-structured interviews, and the application of a questionnaire for data collection. Through the implementation of quality tools and the concepts disseminated by Lean and Green it was possible to identify the main waste and environmental impacts present in the line. It was observed that the tread supply, high turnover, and lack of training were responsible for the main wastes identified. Regarding environmental impacts, rubber and steel wire waste from the retreading process were identified, in addition to chemical products and polluting activities such as the boiler. It was concluded, therefore, that the application of lean production principles and tools can help reduce environmental impacts, demonstrating that there is a positive synergy between the Lean and Green philosophies.
