Information : Waste Management
Waste management is a major cost concern for industry and a major environmental concern. Texas Instrument/Semiconductor Group/Military Products (TI/SG/MP) has responded to these issues with an aggressive program to reduce the generation of waste, recycle produced waste, and neutralize material that must be discarded.
The plant has recycled aluminum, cardboard, and other packaging materials for several years. Over 93,000 pounds of material, representing 56% of the total material used, was recycled in 1991 compared to a national average of 25%. Landfill costs have been cut in half. The heavy metals removal system removes all toxic material from waste water so the remaining effluent can be safely discharged into the sewage system; and the non-hazardous metal hydroxides are shipped to a Class I disposal site.
An innovative idea included the conversion of an undrained basin next to the plant into a natural water source for irrigation and cooling. Total cost of the project (including wells, pumping, and filtering equipment) was $90,000. A total of 30 million gallons was used during the first year. This amount would have cost $100,000 if purchased from the city. Two-thirds of the water goes to cooling towers.
