Polyester is basically plastic, which is made from petroleum. Recycled polyester is typically made from recycled plastic bottles. It’s still plastic (which takes decades to break down, and even then just becomes tiny little microfibers, which is a whole other problem), but it does reduce our dependency on nonrenewable fossil fuels.
Recycled polyester production uses less water and energy and emits less CO2 than virgin polyester. So hey, it’s not perfect, but it’s definitely better!
