How sustainable is recycled polyester?

Nearly half of the world’s clothing is made of polyester and Greenpeace forecasts this amount to nearly double by 2030. Why? The athleisure trend if one of the main reasons behind it: an increasing number of consumers are look for stretchier, more resistant garments. The problem is, polyester is not a sustainable textile option, as it is made from polyethylene terephthalate (PET), the most common type of plastic in the world. In short, the majority of our clothes come from crude oil, while the Intergovernmental Panel on Climate Change (IPCC) is calling for drastic actions to keep the world’s temperature to a maximum of 1.5 °C above pre-industrial levels.
