Here's a case study of a company that liked it in Texas.  These case studies are

1.	GENERAL INFORMATION

	Location: 				San Antonio
	Number of Employees:		45,000
	Industry:				Food & Drug
	Waste Reduced:			Parts Washer Solvent
	Process: 				Distillation
	Contact Person:			Tommy Johns, (210) 938-5628
	Information Current as of:		May 20, 1998

2.	DESCRIPTION OF THE PROJECT
     
With the installation of the Valvaline SYSTEM-ONE parts washer with distillation
unit, HEB fleet  maintenance was able to totally eliminate the hazardous waste
stream of parts washer solvent.  The system uses a high flash solvent (>140
degrees Fahrenheit) that does not contain any carcinogens or any listed
material.  

The process uses a 30-gallon system that separates contaminated solvent from
clean solvent.  With only a four minute downtime, the operator is able to flush
the five gallons of used solvent into the vacuum distillation unit and begin the
recycling process, while at the same time replenish the five gallons of used
solvent with clean solvent.  The distillation process takes about six hours;
however, you are able to use the parts washer in only four minutes.  After the
unit has completed the distillation of the solvent, the operator is able to dump
the still bottoms into the waste oil, which is then recycled.  

Pure solvent is always readily available on demand without the need to wait for
periodic deliveries and hazardous waste disposal services.  
	

3.	INNOVATIVE APPLICATION OF TECHNOLOGY

The system eliminates waste recovery services and could avoid classification as
a waste generator.  It also eliminates potential liabilities for improper handling,
storage, and transportation of waste material.  

SYSTEM-ONE is a totally enclosed treatment that separates solvents from oil
and other impurities.  The resultant residue meets the regulatory definition of
used oil under 40 CFR 260.10 and may be managed as a used oil and is exempt
from hazardous waste disposal regulation.  But remember, the responsibility
for proper chemical management rests with the user.  The user must ensure
that the solvent is never contaminated with a hazardous material or waste.
4. 	ENVIRONMENTAL BENEFITS

This system will allow HEB to eliminate a large hazardous waste stream.  The
new solvent does not exhibit any characteristics of hazardous waste therefore
eliminating a hazardous waste stream into the environment.  

5.	COST SAVINGS/BENEFIT

The system will save $49,000 in service and disposal costs over a period of 60
months.  The disposal costs will never be zero.  The elimination of the
hazardous waste stream will keep some of our sites Small Quantity Generator
Conditionally Exempt.
