Figure 14.2 Survey data collected by SIC group.

■ Hazardous wastes were not reported by many manufacturing respondents. These
companies view this data as sensitive, and since it is illegal to dispose of hazardous
wastes at landfills, these types of wastes were not included as responses in most
cases. Generally hazardous wastes compose a very low percentage of the total
waste stream.

Table 2.2 displays the EPA volume to mass conversion factors for common waste
components. The conversion factors were obtained from EPA (www.epa.gov/epaoswer/
non-hw/recycle/recmeas/, retrieved July 10, 2007).
The following densities in Table 14.1 were experimentally determined at the
University of Toledo from 1998 through 2007. The densities are used during the data
analysis phase of waste assessment to convert volumes.
