TI continued to reduce waste and increase recycling in 2012, which limited environmental impacts and reduced costs. We implemented a new global goal for manufacturing operations to select one or more chemicals based on risks and hazards, and reduce its use by 3 percent over the year. More than a dozen sites worldwide met or exceeded this goal. Reductions ranged from using less-concentrated formulations, substituting less-hazardous chemicals, and improving process efficiencies to use fewer chemicals.
We continued to reduce the use of certain hazardous chemicals, improve recycling, and reduce building waste. Our South Campus in Dallas, Texas, where our corporate headquarters is located, employs a full-time person to sort and manage waste. This campus has reduced office waste by 50 percent.
In 2012, TI:
- Ended the year with a worldwide efficiency (recycling) rate of 93 percent. This was a 1 percent improvement over 2011 and just 2 percent short of our goal.
- Kept 23,714 kilograms of silicon wafers out of the waste stream by selling them to solar-panel fabricators. Since 2003, our recycled wafers have produced enough solar panels to supply electricity year-round to 2,100 homes and prevent 14,600 metric tons of carbon dioxide from entering the atmosphere – the equivalent of planting more than 700,000 trees.
- Manufacturing sites around the world:
- Collected more than 100,000 gallons of sulfuric acid discarded from manufacturing processes and reused it in other processes.
- Collected more than 120,000 gallons of sulfuric acid discarded from manufacturing processes and shipped it off-site for recycling and reuse by others.
- Collected more than 250,000 gallons of isopropyl alcohol discarded from manufacturing processes and shipped it off-site for recycling and reuse by others.
- Reused wafer-polishing slurry multiple times, saving more than 75,000 gallons of slurry.
- Recycled more than 850 metric tons of compostable organic waste.
- In celebration of Earth Day 2012, employees recycled:
- 3,300 pounds of paper and electronic equipment in Santa Clara, Calif.
- 7,000 pounds of electronic equipment in South Portland, Maine.
- 9,500 pounds of televisions, computers and other electronics in Dallas, Texas.
In 2013, TI aims to:
- Continue promoting the goal for each site to reduce the use of at least one manufacturing chemical by 3 percent.
- Continue reducing hazardous chemicals used at each manufacturing site.
- Continue evaluating methods to collect isopropyl alcohol used in our manufacturing process for resale.
