Caracterização operacional e proposta de aplicação do Lean Manufacturing em uma empresa de triagem de materiais recicláveis no Sudoeste do Paraná

Abstract

This study aimed to analyze the operational process of the company Reciclagem Pato Branco EIRELI, located in the municipality of Pato Branco – PR, and to propose improvements focused on efficiency and sustainability, through the application of quality management tools and the Lean Manufacturing model. Through direct observation, interviews, and analysis of internal documents, it was possible to identify bottlenecks in the collection, sorting, and storage flows, reflecting the need for greater standardization and control of activities. The application of VSM, 5S, Kaizen, Ishikawa, and Pareto tools allowed for a systemic understanding of the process stages and their main sources of waste. Among the most relevant results, a 16,7% reduction in average processing time, a decrease in rework and accumulation of unclassified materials, and increase in employee engagement stand out. These advances, although moderate, demonstrate the potential of continuous improvement methodologies for small businesses, especially in the recycling sector, where there is a scarcity of technological and management resources. It can be concluded, therefore, that the integration between quality management and environmental sustainability represents a promising path for strengthening the recycling sector.
