On September 4, 2024, at 12:30 PM, the Faculty of Nursing, Mahidol University, organized a "Workshop DIY: Personalized Water Bottles" in front of the Phatthara Maharajkarun Conference Room, Faculty of Nursing, Mahidol University, Salaya. This event is part of the "NS ZERO WASTE" project aimed at waste management within the Faculty of Nursing. The workshop was held for the faculty staff and students with the goal of encouraging them to bring their own water bottles and creatively personalize them. By decorating their own bottles, participants take pride in their reusable containers, making them more enjoyable to use. This aligns with the 3R approach (Reduce, Reuse, and Recycle) and serves as a great step toward reducing daily waste. Additionally, the activity raised awareness among staff and students to use resources efficiently, helping reduce landfill waste and incineration, which contributes to global warming. The fastest and most effective way to make a change is to start by altering our own habits.
