Number of krathong floats in Bangkok continues to drop over eight years

WEDNESDAY, NOVEMBER 05, 2025

The number of krathong floats in Bangkok continues to decline, with a significant drop in foam floats over the past eight years. Environmental awareness drives change ahead of the 2025 Loy Krathong festival.

The number of krathong floats in Bangkok has been steadily decreasing over the past eight years, particularly those made of foam, as city residents have become more environmentally conscious, the Bangkok Metropolitan Administration (BMA) announced on Wednesday.

Decrease in Total Floats Collected

The BMA reported that the total number of floats collected after the Loy Krathong night in 2017 was 811,945, which dropped to 514,590 in 2024, marking a 35.6% decrease.

Sharp Decline in Foam Floats

The number of krathong floats made from foam has seen a significant reduction of 84%. In 2017, 51,926 foam floats were collected, but by 2023, this number had plummeted to 8,270.

Encouraging Environmentally-Friendly Celebrations

Meanwhile, Surin Worakijthamrong, Director-General of the Pollution Control Department, urged the public to be more environmentally conscious when celebrating Loy Krathong.

He encouraged people to take three key steps to reduce the environmental impact of the festival:

  • One family, one float: He suggested that if each family releases only one float together, it would significantly reduce the total number of floats released into the water.
  • Use naturally degradable materials: Surin urged people to use floats made from natural materials like banana leaves, banana stems, lotuses, or even ice, all of which are biodegradable.
  • Try online floats: For a more environmentally friendly option, he proposed that people consider using virtual floats through online platforms instead of physical ones.

Avoid Using Bread Floats

Surin also warned against using bread to make floats, as the large volume of bread released into the water at once could lead to water pollution.
