목차

a. Disposable diapers, manufactured from paper and petroleum product, are one of the most convenient diapering system available, while cloth diapers are often believed to be most environmentally sound. The evidence is not so clear-cut, however. This problem will quantitatively examine the relative energy requirements and the rates of waste generation associated with diapering systems. Tree type of diapering systems are considered in this problem: home-laundered cloth diapers, commercially-laundered cloth diapers, and disposable diapers containing a super-absorbent gel. The results of life cycle inventories for the three systems are given below.

b. Complete the table given below. Remember to use the equivalency factor determined for cloth and disposable diaper determined in part a). Based on the assumption you made in part a). How accurate are the entries in the table?

c. Using the data given below, determine the percentage of disposable diapers that would need to be recycled in order to make the solid waste landfill requirements equal for cloth and disposable system.

본문내용

(x: Percentage of diapers recycles, y: Solid waste per 1000diaper uses)

If, y= 2.3
x = -(2.3-17)*100/16.2 = 91 %
