Over the 30 or 40 years of the history of recycling and reuse of PET bottles, most of the thinking has been devoted to remanufacturing them into fibers, drink containers, or other plastic items. No one, it seems, has ever thought about turning them into construction materials, which have to meet high standards for resistance to wind, fire, and earthquakes.
