2011 performance
Results | Looking ahead
TI continued reducing waste and increasing recycling, not only to save waste disposal costs but to limit environmental impacts.
Our goal was to target either an overall 95 percent efficiency rate for recycling efforts (meaning that only 5 percent of the company's total used materials will be sent for disposal) or a 5 percent year-on-year improvement in disposal volumes. We narrowly missed achieving this milestone, as we ended the year with a worldwide efficiency rate of 92 percent.
Our Texas facilities continued to make advancements in recycling, reducing building waste by half at our South Campus alone, where 4,000 employees work. We hired a full-time person to sort and manage waste.
TI India was recognized for its strong solid-waste management program. It received an "Environmental Champion Award" from municipal authorities for setting up 42 solid-waste segregation categories and increasing its recycling rate from 56 percent to 90 percent since 2008.
Results
In 2011, TI:
- Ended the year with a worldwide efficiency (recycling) rate of 92 percent, just 3 percent short of our goal.
- Kept 7,166 kilograms (nearly 8 tons) of silicon wafers out of the waste stream.
- Implemented a slurry recycle program that allows the reuse of a slurry process chemical multiple times before disposal. The program saved more than 60,000 gallons of slurry.
- Increased organic recycling at TI's North Texas campuses by more than 155 percent over the past four years; 109 tons of organic waste was recycled in 2011. Additionally, we were able to come full circle with the organic recycling process when we began purchasing mulch for Dallas-area sites directly from the vendor that composts our organic waste.
Looking ahead
In 2012, TI aims to:
- Boost our overall efficiency rate back to 95 percent.
- Reduce chemical use by 3 percent at manufacturing sites.
- Evaluate recycling programs at our newly acquired U.S. site in Santa Clara, Calif., and roll out recycling programs at our sites in Tucson, Ariz., and Manchester, N.H.
- Recycle redundant electronic equipment such as computers and hard drives following the acquisition of National Semiconductor.
- Evaluate methods to collect isopropyl alcohol (IPA) used in our manufacturing process for resale. This is feasible in our newly acquired site in Maine, now that the state allows IPA recycling.
