  1. Recycling

  2. Upcycling

  3. Downcycling

  4. Composting
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Recycling in the context of textiles involves breaking down textile waste into its constituent materials, such as fibers, which can then be used to create new products. This process helps to reduce the amount of waste sent to landfills and promotes the circularity of materials in the fashion industry.
