Bangkok Metropolitan Administration (BMA) is asking city residents to go "zero-foam" for this year's Loy Krathong festival and urging use of biodegradable floats to help protect the environment.
The deputy director of City Hall's Environment Department, Worranut Suaykhakhao, said despite previous pleas to go foam-free, about 20,877 out of the 639,828 floats collected by BMA's waste collection units after last year's Loy Krathong festival were made from foam.
