“Paper or plastic?” asks a checkout clerk at your grocery store. According to Time magazine (August 13, 2007, page 50), paper bags cost 5.7 cents each as opposed to 2.2 cents per plastic bag. After leaving the store with several plastic bags, you decide to do some research on paper versus plastic bags. The Time article goes on to inform you that the United States uses 12 million barrels of oil to produce its plastic bags consumed annually. Furthermore, paper bags consumed in the United states equate to 14 million trees a year. What other factors might go into a multi attribute analysis of the pros and cons of paper versus plastic bags (e.g., littering, leak potential, biodegradability, transportation to landfills)? Use the additive weighting technique to assess the impact of imposing a 3 cent “finder’s fee” for returning plastic bags to an approved recycling center.
