5.1 Texas Instruments
One of the top electrical and electronic industries in the USA is Texas Instruments,
which is the fifth ranking in the manufacture of semiconductors [22]. With headquarter in Dallas and worldwide manufacturing facilities, Texas Instruments workforce is approximately 36,000. The company is leading in the design and supply of
Digital Signal Processing Solutions (DSPs) and others like materials and controls,
educational and productivity solutions, and digital imaging. Some other manufacturing industries particularly inorganic chemical manufacturers operate within the
facility in the company to facilitate supply of resources needed for production
[23]. Prominent among the Texas Instrument facilities is the Texas Instruments
Sherman located near Dallas, which produces chips. The 1997 verification of
industrial waste generated in the facility waste stream is illustrated in Table 4.59.
Facility, primarily for waste minimization as well as cost benefit. By 1996,
following the technology and compliance with various environmental acts, the
Sherman plant was able to reduce the quantities of hazardous wastes it generated
to 60% [24]. Some of these approaches are summarized in Table 4.60.
