ISK Biosciences Corporation

Year Submitted: 2003

Process: Air compression

Industry: Chemical Manufacturing

Wastes Reduced: Oil

Equipment: Filter and Pump

Location: Houston, Greens Bayu Facility TX

No. of employees: 278

Contact: John Stansburry

Phone: (713) 450-6458


Mechanics at ISK recognized that the spent oil that they changed on a weekly basis did not seem to have lost it's lubricating qualities. If the oil could be filtered within the filtration system significant savings could be adchieved.

P2 Application:

Resources were allocated to rent a pump and filter system to try out the idea. Once the oil was filtered to remove the particulates, the oil met all specifications required for use in the refrigeration system. A filter was purchased (Hilco Fluid Purification in Elmira, NY), and together with the pump (Viking positive displacement pump) and labor the system cost $800.

Environmental Benefits:

Approximately 6,000 pounds of oil a year no longer becomes a waste because of this project.

Details of Reductions

Additional Information :

New oil purchases were reduced by $52,000 a year, disposal of used oil was reduced by $26,000 a year and labor savings (from reduced change out of old oil) were $5,600. Total savings for a $800 investment was $83,600.
