TI strives for zero waste in all aspects of our operations.
We work to convert streams that might produce waste into a
process stream that loops back to feed itself anew.
We particularly acknowledge the "cycle" part of recycling.
Reducing our use of chemicals or disposables that are difficult
to reprocess has been identified as the logical starting point.
When it comes time to dispose of used material, all TI production
sites adhere to written processes tailored specifically for
each waste stream. At the end of the procurement-use-recycle
process, we start over again, replacing materials with recyclable
substitutes if possible.
The regulatory climate of any given site worldwide affects
the way a recycling program is operated. Some sites can burn
waste for energy production and count that as recycling. Other
sites have very stringent regulations prescribing what can
be recycled and how. Instead, we draw on scientific principles
to guide our procurement, use and disposal of materials used
in wafer manufacturing and other processes.
Each of TI's 11 major production sites around the world operates
a robust recycling program. Globally, more than 30,000 employees
participate in recycling efforts. They learn about programs
we offer through employee awareness training and our internal
TI Recycling Web site.
Different jurisdictional authorities are responsible for
classifying industrial waste, non-industrial waste and hazardous
waste. These wastes span everything from absorbents associated
with cleaning processes and wood and paper products to cafeteria
waste, scrapped computer chips, and wafers.
We work to recycle office refuse through a variety of means. Workplaces and conference rooms have recycling bins for office paper, corrugated boxes, pamphlets, folders and aluminum cans. Recyclables are picked up from office as well as factory areas, transported to our building docks, weighed, sorted and bundled, and sent to recycling centers.
In Texas, we continued to roll out an organic cafeteria waste
recycling program at three facilities in 2007 after realizing
success at our Kuala Lumpur, Malaysia, site. We shipped approximately
193.4 tons of food to the city of Plano for composting. Plano
trucks pick up the organic waste free of charge, resulting
in additional cost savings for TI. Because of the program's
success, TI won the city's 2007 Environmental Star of Excellence
Award for Outstanding Organic Recycling. We are now working
to identify ways we can recycle food containers and utensils.
In Malaysia, the site sends approximately 1,400 pounds of
cafeteria waste per day to its outdoor rapid composting system,
the first of its kind in that country. The composting machine
runs nonstop to aerate the material and break down waste.
Every two days, the partially composted material is sent to
a facility where it is sifted to make fertilizer for organic
Industrial waste originates from industrial operations and
is classified according to the regulating body in the region
of origin. It primarily includes chemicals used in manufacturing
In 2007, TI generated an estimated 28,188 tons of industrial
waste. Of this, about 25,899 tons were recycled and some
2,289 tons were disposed of in permitted landfills.
TI also follows steps to either substitute or recycle waste
from manufacturing operations. We have reduced chemical use
by recapturing and recycling valuable pump oils. In some cleanup
applications, we use high-pressure water in place of chemicals.
Elsewhere, we replace chemicals with environmentally benign
substitutes when possible.
The company reuses materials and resources in several different
ways. TI has implemented methods to recover metals from solids,
liquids and sludge. Some items, including certain solvents,
are burned in boilers or industrial furnaces for energy recovery.
Chemical reuse programs have been put in place at TI locations
worldwide. We also recycle water used in our fabrication processes
by feeding it to utility plant cooling towers for heating
and cooling purposes.
Silicon wafer recycling
TI has been working for several years to keep scrap wafers
out of the waste stream by recycling them for use in solar
energy cells. TI sells scrap wafers to solar energy cell manufacturers
in the United States, Japan, Germany and Hong Kong. The German
and Japanese governments have significant green energy programs
in which they subsidize the creation and use of solar cells
to produce electricity.
Our recycled wafers have produced enough solar panels to
supply hundreds of homes with electricity year-round, which
may have kept 14.5 million pounds of carbon dioxide from being
released into the atmosphere. The November 2007 issue of Fast
Company magazine ranked TI's silicon wafer recycling effort
17th in a list of 50 programs that top U.S. companies are
pursuing to advance corporate America's green movement.
Back to top
TI recently modified our solid waste recycling goal to better
reflect actual environmental impacts. Rather than simply measuring
recycling rates and waste reduction, this new goal measures
efficiency in recycling and minimizing the quantity of chemicals
and materials that leave our sites for no other use or purpose
except disposal. This metric tracks the efficient use of resources
by comparing the weight of reused or recycled material to
the weight of disposed material.
Our goal is to target either an overall 95 percent efficiency
rate for recycling efforts or a 5 percent reduction in waste
disposal from the previous year. In general, our 2007 efficiency
performance did not meet our goals. Although nearly every
site achieved at least one goal, we ended the year with a
worldwide efficiency rate of 91 percent and a 35.7 percent
increase in year-on-year waste disposal.
Our results were negatively impacted due to a number of wastewater
issues at our Stafford, Texas, facility. Excluding this site,
the results worldwide are 95.1 percent efficiency and a 14.6
percent improvement in year-on-year waste disposal. Twelve
of 16 TI sites achieved either a 95 percent recycling efficiency,
a 5 percent improvement from the previous year, or both.
In 2008, TI will continue to focus on opportunities to expand
our recycling activities, thus improving our environmental
efficiency. These focus areas will include making additional
efforts to ensure that a larger percentage of the content
in organic recycling waste streams is suitable for composting.
