No bioplastics then? Or plastics recovered at the end of their life or from industrial waste?
Plastic is a material of organic origin. It breathes, absorbs water, changes over time. It loses aesthetic and mechanical qualities in contact with air and atmospheric agents. To recycle it post-use it is often necessary to add virgin material. There are no chairs that have an infinite life for the simple reason that plastic cannot be recycled indefinitely, if it were really possible and rational to do so. It is among those materials that respond to the laws of organic chemistry, such as plants, animals, humans. All things that die, come to an end.
