BANGKOK, THAILAND — Thousands gathered along the Chao Phraya River on Wednesday evening, where Bangkok officials measured a steep drop in post‑festival waste and hailed the 2024 Loy Krathong celebration as one of the city’s most eco‑friendly yet.
Cleaner Waters and Lower Waste
According to Pornprom Vikitsreth, adviser to Bangkok’s governor, city cleanup teams collected roughly 510,000 Krathongs after this year’s festival across more than 30 riverside locations. He confirmed that 98 percent of the decorative floats were biodegradable, describing the reduction as proof of progress. “BANGKOK SHOWS THAT TRADITION AND SUSTAINABILITY CAN MOVE TOGETHER,” he said at a midnight briefing at City Hall on Ratchadamnoen Avenue.
The Bangkok Metropolitan Administration (BMA) reported that the total volume of foam debris had dropped to almost zero, a distinct change from waste levels recorded in 2023. Street cleaning units completed full river sweeps before 3 a.m. Thursday, ensuring no remnants clogged the Chao Phraya’s main current.
Residents Switch to Natural Materials
City inspectors noted that residents increasingly crafted their offerings from banana leaves, bread, and flowers, replacing plastic frames once found in almost every third Krathong a decade ago. Vendors at Pak Khlong Talad Market in Bangkok’s Pom Prap Sattru Phai District said average sales of biodegradable materials rose by 15 percent in the week before the event.
Environmental officers from the Department of Environment Quality Promotion, led by Director Somchai Phonrat, inspected five disposal sites on November 28, confirming that the compostable contents will be recycled into fertilizer within three months. The department also measured improved dissolved oxygen levels in the river at Si Phraya Pier, suggesting cleaner water for local fish habitats.
Safety Efforts Reduce Injury Risks
During inspections at Saphan Phut Pier, Pornprom Vikitsreth praised festival goers who removed metal nails and pins from their floats before release. The BMA logged zero injuries among sanitation workers this year, compared with seven hand injuries reported in 2022. “THE SMALL DECISION TO REMOVE METAL MAKES A BIG DIFFERENCE TO OUR CLEANUP TEAMS AND ANIMALS,” Vikitsreth told reporters late Wednesday night.
Emergency volunteers under the Poh Teck Tung Foundation deployed 120 workers along a six‑kilometre river stretch and retrieved remaining Krathongs within four hours of the event’s end. All collected waste was transferred to the Ministry of Natural Resources and Environment’s recycling depot in Bang Khun Thian District by 9 a.m. Thursday.
Festival Tradition Meets Responsibility
The Loy Krathong festival, celebrated annually on the full moon of the 12th lunar month, carries themes of gratitude and renewal. In the capital’s 2024 edition, local authorities turned those sentiments into measurable environmental results: fewer pollutants, faster cleanup, and healthier wildlife. BMA spokesperson Chanya Wongsek announced that next year’s target is to cut remaining non‑organic items below one percent and expand volunteer cleanup teams by 25 percent citywide.
“IF WE KEEP THIS MOMENTUM, BANGKOK CAN SET THE GREEN STANDARD FOR EVERY THAI WATER FESTIVAL,” she said.
