Waste Less Week returned to Bangkok Patana School for its 11th edition, and once again our community came together to learn, reflect and take action. This year’s focus on SDG14 – Life Below Water, placed our oceans, rivers and marine ecosystems firmly at the centre of the week, reminding us that what happens on land does not stay on land.
As always, Waste Less Week was proudly student-led. Across the week, learners of all ages designed and facilitated activities that were engaging, accessible and grounded in real-world action. From the moment students arrived on campus, the theme was visible and tangible. Blue SDG14 smoothies appeared in the smoothie bar, sparking conversations about spirulina, algae and the role oceans play in food systems. In the canteen, low-carbon rice was served all week, prompting many to pause at the scale of our collective consumption when they learned that Patana eats almost a tonne of rice every week.



Learning extended beyond food. Eco Heroes featured daily in notices, highlighting Thailand-based NGOs doing vital work to protect marine environments. Displays across the school showcased our Biodiversity Audit findings, while the libraries transformed into hubs of curiosity with interactive SDG14 exhibitions and carefully curated book collections for all ages.



The week was rich with shared experiences. Staff came together for a dedicated CPL session exploring SDG14 and its relevance to teaching and learning. Students had the opportunity to work alongside Shark Guardian, engaging in age-appropriate workshops that connected ocean conservation to plastic waste, consumer choices and local action. Practical, playful learning took centre stage mid-week with the Patana Pacific Garbage Patch Dash in the 50m pool and the Foundation Stage Sensory Stream Garbage Patch, where even our youngest learners explored big ideas through hands-on discovery.




Creativity and reflection rounded out the week. A lunchtime screening of Ocean is Life, filmed in Koh Tao, invited students and staff to pause and reflect, popcorn in hand, while waste sorting games in the Lounge turned sustainability into a collaborative challenge. The week closed gently, with shared reading in the Foundation Stage, as older and younger students explored SDG14 stories together.
Perhaps the most powerful aspect of Waste Less Week was its emphasis on small steps. This was not about perfection or grand gestures, but about noticing habits and making thoughtful choices. Reusable bottles, better waste sorting, fewer single-use plastics, sustainable seafood, conversations at home, and moments of curiosity. As we look back on a vibrant and purposeful week, the question remains open to all of us: What are your small steps? Protecting life below water starts with everyday decisions above it. When taken together, those small steps ripple outward, creating meaningful change for our oceans and for future generations.
