e-waste management
Some time after an electronic product is purchased, it
becomes obsolete to the owner. Industry data show that the
average lifespan of televisions and radios is 8 years, whereas
that for air conditioners, washing machines, and refrigerators
is 10 years. This information is used to determine the
number of electronic products that become obsolete in a
given year. In the case of televisions, all units bought in a
certain year will become obsolete after 8 years. For instance, in 1985, 568,870 televisions were sold. All these became obsolete in 1993, 8 years after being purchased.
