Can we fully manage the risks -- both environmental and health-related-- that come with recycling plastic into polyester?

Among the numerous initiatives that have been taken to recycle plastic for further use and reduce the human carbon footprint around the world, one of the most worthy is transforming old, shredded plastic into polyester thread that may be used in clothing, upholstery, and many other purposes. The complex, multi-tiered process (shown in the video below) involves shredding the recycled plastic to remove unwanted liquid, bathing the plastics multiple times in corrosive material and mixing them together for ten hours, sending the mixture through a rotating screw at 270 degrees Celsius, and forcing the melted mixture into a sift to create the threads. The unrefined threads are then combined, stretched, torn, and bonded together multiple times to produce a uniform material that can be used for clothing.
