Polyester is a synthetic fabric that is derived from petroleum, so a non-renewable material. It is one of the most common fabrics in the world because of its versatility and how cheap it is to produce. Polyester is typically a soft fabric, it is made from plastic and is scientifically known as polyethylene terephthalate. The transformation of crude oil into petrochemicals releases toxins into the atmosphere that are dangerous to humans and nature. Plastic materials also releases micro plastics when worn and washed. Polyester material is also used to make Pet-bottles. In recent years it has become popular to make fabrics from recycled Pet-bottles. But recycling Pet-bottles has a functioning system, when Pet-bottles are made into fabric that can not be recycled again. So recycled polyester from Pet-bottles is not a sustainable option.
Polyester is not biodegradable.
