Application of the 5S Technique of Lean Manufacturing to Organize a Laboratory Space and Enhance Productivity Towards a Green University †

Lean manufacturing emphasized reducing waste and improving efficiency, with the 5S methodology, Seiri (Sort), Seiton (Set in Order), Seiso (Shine), Seiketsu (Standardize), and Shitsuke (Sustain) as key tools. This study explored 5S implementation in a laboratory of a university, which initially suffered from disorganization, inefficiencies, and wasted resources. The intervention involved data collection, discussions with lab technicians and students, and layout mapping. After applying the first 4S steps, the lab realized marked improvements in organization, cleanliness, and workflow. Designated storage improved space use, while time-motion studies showed an average 78.6 s reduction in activity times, saving 632 s weekly. A 54% efficiency enhancement has also been achieved. The successful implementation created a safer and more efficient lab environment. The final step, Shitsuke, ensured sustained improvements through training, cleaning schedules, and time management tools. This paved the way towards a green university.
