Polyester is the most common fiber in our garments. We can find it in 52% of our clothes.
Polyester is a synthetic fiber derived from petroleum, a non-renewable fossil fuel. As we know, the transformation of crude oil into petrochemicals releases toxins into the atmosphere that are dangerous for the health of humans and our ecosystem.
The production of polyester is also very energy-intensive.
One of the major problems with this plastic fiber is the fact that it is non-biodegradable.
Furthermore, each time we wash a polyester garment, it releases 1,900 plastic microfibers, ending up in rivers and oceans, and then in our food chain.
