collection boxes located near the copiers and printers and scattered in various offices.
However, less than 40 percent is currently recycled.
Therefore, one of the best strategies for recycling some waste paper is to fully
implement an office-paper recycling program. Table 8.13 illustrates the potential for
recycling based upon the current office paper generation at the company. A descrip-
tion of how to successfully implement such a program is described in Sec. 8.10.14.
Paper recyclers are also listed in the mentioned section.

8.10.5 FLOOR SWEEPINGS

There are 91,052 lb or over 45.5 tons of floor sweepings generated on the plant floor
each year. There are two types of floor sweepings used in the facility: one is chemical
based, the other is sawdust. It is not possible to recycle either type of floor sweepings
due to lead contamination on the plant floor. However, it may be possible to reduce the
amount of floor sweepings that are sent to the smelter at an unknown cost.
To calculate the possible reduction four steps must be followed:

1 Determine the volume of the two sweeping compounds needed to clean up a standard
or representative spill. Specify the compound that uses the lowest volume to clean up
the average spill as C , and the other compound as C , and the volumes determined to
