Once known as a diver’s paradise, Koh Tao is now grappling with a severe waste crisis. The island generates 15–20 tons of garbage daily, which has piled up into a 45,000-ton “trash mountain” after the local incinerator broke down in 2013 and has yet to be repaired.
The massive waste accumulation has not only scarred the island’s landscape but also produced foul odors, leached into the sea, and threatened marine ecosystems—damaging tourism, the community’s main source of income.
A Community-Led Response
Despite the challenges, Koh Tao’s residents are taking action:
- Sorting and separating waste at the source
- Recycling programs to reduce landfill burden
- School-based waste bank initiatives to educate the next generation
These efforts mark a significant shift from environmental crisis to a model for sustainable waste management, offering hope that Koh Tao can reclaim its image and inspire similar efforts across Thailand.
