Practical Information

    Paper or Plastic?

    Yes, paper is biodegradable and made with wood, a renewable resource. Plastic is nasty and does not decompose and is made from gas and oil. So a styrofoam cup is evil and a paper cup is good. Right?

    Chemist Martin Hocking of the University of Victory, BC says you must consider a few other factors. First, it takes six times as much wood pulp (although, not necessarily from rain forests) to produce a paper cup as polystyrene to produce a plastic cup. And manufacturing the paper cup consumes:
    12 times as much steam.
    36 times as much electricity.
    2 times as much cooling water.
    580 times as much waste water.
    Additionally the paper cup contains waterproofing resins (to allow it to hold some of that precious rainwater), making it impossible to recycle. The plastic version can be turned into lawn furniture and flower pots, and doesn't burn your fingers when filled with hot coffee.

    Sure, there are other considerations. But be advised, there are also other considerations to your other considerations!

    Every now and then two numbers meet, link, and become forever binary.
