Ask A Scientist!


Conversely, paper and plastic are composed of fibers and polymers. These fibers and polymers can degrade over time just like the fibers in a well-worn shirt or teddy bear. Office paper tends to be composed of the newest fibers, and is recycled to provide recycled office paper, which in turn becomes cardboard. Well-worn fibers tend to find their resting place in the form of tissue paper that most of us are very pleased not to recycle. Not all polymers find themselves in a downward spiral towards the dump. Some polymers, like PETE (code 1), are broken back down to their starting components and reused completely or the polymers are reformed into fibers for clothes and plastic lumber. Chemists are discovering new methods to make polymers from renewable and completely recyclable materials, but until these are available glass, aluminum, and steel provide the most bang for your recycling buck.
