The issue of high interest in fast fashion has resulted in a huge surge in the volume of second-hand clothing imports in Indonesia.

By 2022, the volume of collected used clothing waste will reach 2.3 million tons. Clothing imports in Indonesia reached 2.25 million tons, causing continuous damage to the natural environment.
