ConAgra Foods- Grocery Products Co.

Year Submitted: 2006

Process: Closed Loop Cooling System

Industry: Food/Beverage Manufacturing

Wastes Reduced: Phosphoric Acid and Chlorine Dioxide

Location: Fort Worth TX

No. of employees: 118

Contact: Deirdre Cummings

Phone: 817/810-5032


Replace chemicals used in cooling system with non-regulated, less-expensive chemical. Initially changed from Phosphoric Acid to Chlorine Dioxide. Replaced Chlorine Dioxide with Sulfuric Acid in liquid form.

  • Comments: The cost difference between Chlorine Dioxide and Sulfuric Acid was significant with Chlorine Dioxide selling for $15.00 per gallon while Sulfuric Acid is $.99 per gallon.
    The Sulfuric Acid also requires less monitoring to maintain the pH level of the water, which resulted in a labor savings.

Details of Reductions

  • Chlorine Dioxide

Additional Information :

Since the acid is injected directly into the system there is no atomization and it remains in a liquid state. Therefore, it is not regulated under SARA 313.
