Lean manufacturing is a methodology that focuses on continuous improvement and waste elimination. This methodology is supported by its tools, namely, lean tools, to identify and eliminate waste. This article presents a model for reducing waste in the Peruvian textile industry. The Peruvian textile manufacturing industry is characterized by its manual or semi-manual operation, differentiating itself from foreign competition, which tends to use automated machinery. Such foreign competition forces the local industry to maximize its operations. In a case study of a company, waste identified was reprocessing, with an index of 21.63%. To reduce this waste, tools identified in the literature, such as lean tools, 5S, workstation design, and process management, are used for reducing rework to 11.58%.
