Grupo Fleury's project consisted of reviewing the supply flow of methyl alcohol, an input used approximately 4,000 liters per year in the company's operations, with the aim of reducing waste generation and bringing operational gains to the company. In development with the supplier, the product, previously sold in glass bottles, is now supplied in returnable metal gallons, reducing the generation of chemical waste. Throughout the process, safety issues were also duly observed, with the search for approved products.
