Corpus Christi Army Depot
A system was installed in December of 1994 that reduced the amount of hazardous wastes generated by solvent-based degreasers and parts washers. The old equipment used 1,1,1 Trichloroethane (TCE) which is a hazardous waste.
The installation of 6 agitated aqueous units and 7 high pressure aqueous spray units replaced a process that ceased production as of December 31, 1995. CCAD has experienced lower operating costs since the implementation of this equipment.
The system reduced or eliminated hazardous wastes from cleaning units that used chlorinated solvent degreasers and cleaners. TCE is a volatile solvent and is considered an ozone depleting organic compound. The removal of this substance eliminates a Class I ozone depleting substance and reduces hazardous waste volumes.

Additional Information :
The initial capital costs were $577,000 with a yearly savings of $248,000. The savings are from the reduction of hazardous waste regulations and disposal. The payback period is approximately 2.3 years.
