33/50 Program: The Final Record

Production-related Waste by Chemical

Despite the trend for 33/50 chemicals overall, facilities reported increasing production-related waste from 1991 to 1995 for half of these chemicals. Tables 8 through 12 (Table 8, Table 9, Table 10, Table 11, Table 12) present production-related waste data by waste management method for each of the 33/50 Program chemicals. Figure 14 illustrates total production-related waste by chemical.

As with releases and transfers, the 33/50 chemical with the largest production-related waste was toluene, mostly recycled on site. Facilities reported 1.341 billion pounds of production-related waste for toluene in 1991, increasing to 1.702 billion pounds in 1995. The increase continued in 1996, to 1.816 billion pounds, and facilities projected a total of 1.838 billion pounds in 1998. (See Table 12.)

This and other increases were offset by sizable decreases from 1991 to 1995 in production-related waste of a few 33/50 chemicals. The largest reduction occurred in reporting for the ozone depleter 1,1,1-trichloroethane (TCA), again reflecting the influence of U.S. action to implement the Montreal Protocol. Facilities reported 324 million pounds of TCA in production-related waste in 1991 (about 40% in recycled on-site and about 40% released on- and off-site). This total dropped to 94 million pounds in 1995 and 53 million pounds in 1995. By 1998, facilities expect to report 17 million pounds of this chemical in production-related waste.

As shown in Figure 15, the 33/50 chemicals have varied considerably in the rate and direction of changes in production-related waste from 1991 through 1996 and projected to 1998. As with releases and transfers, organic chemicals have more consistently decreased in production-related waste than the inorganics.
