Hoechst Celanese

Year Submitted: 2003

Process: Chemical Production

Industry: Chemical Manufacturing

Wastes Reduced: Process Chemicals

Location: Bishop TX

No. of employees: 1100

Contact: Dan Postolowski

Phone: (512) 584-6000


In 1993, Hoechst Celanese began supplying a new product called Sulform. This product is a blend of two co-product materials that are produced at the Bishop Facility. Up to this point, these materials have been disposed of by deepwell injection since a market for these materials had not been found. By combining these materials and demonstrating by analysis that Sulform could be used in certain chemical processes, a market has been developed. Shipments have begun to our first customer

P2 Application:

Other materials like ours are being disposed of by other plants and companies, but by combining these streams a successful new product has been developed for this plant.

Environmental Benefits:

Sale of this material will eliminate the disposal of these streams at Hoechst Celanese and take the place of other previoulsy purchased raw materials at the customer's site. The total waste reduction volume is 16,000 tons per year. SARA waste reduction is negligible. Waste reduction will also take place at the site of the customer since the production volume requirements for the previous raw material will be decreased as a result of the consumption of Sulform. The sale of a similar co-product material that is currently stored in surface impoundments will hasten the emptying and closure of these impoundments at the Bishop facility.

Details of Reductions

Additional Information :

Reduction of disposal costs.
