This plastic is one of those modern chemical compounds found in so many products, it's pointless to count — from Spandex to garden hoses, for a start — and it is prized for both its flexibility and rigidity. The problem is that like many other polymers, it does not break down readily. This means it persists in landfills, as Fast Company points out. It burns pretty well, but that releases carbon monoxide and other gases into the atmosphere, so it's a nonstarter in most situations. Something that can degrade it naturally would be a better solution.
