Koch Industries Inc., parent company of Flint Hill Resources, which just announced a joint venture with Benefuel to develop biodiesel refineries across the U.S., is making a $1 million donation to support relief efforts in Oklahoma following the tornadoes that devastated the cities of Moore and Shawnee, and affected other areas of the state this week.

Half of that amount will be given to the OK Strong Disaster Relief Fund established by Governor Mary Fallin in coordination with the United Way of Central Oklahoma. The other half will go to the American Red Cross and The Salvation Army to help affected families with their most urgent needs, including housing, transportation, clothing and more. In addition, Georgia-Pacific, a Koch company, has donated six truckloads of products from its Muskogee, Okla., Fort Smith, Ark., and Naheola, Ala., facilities including Angel Soft and Quilted Northern bath tissue, Sparkle paper towels, Dixie cups and plates, and Mardi Gras napkins.

“Koch has deep roots in Oklahoma, and we want the communities of Moore, Shawnee and others throughout the state to know we stand with them and pray for them as they begin the difficult process of rebuilding their lives,” said Dave Robertson, president and COO of Koch Industries.

Several Koch companies have a presence in Oklahoma, including Georgia-Pacific in Muskogee; Koch Nitrogen Company in Enid; and John Zink Hamworthy Combustion in Tulsa, with a total of nearly 2,000 employees.
