CASE STUDIES FOR TEXTILE PRINTING
CASE NO. 4
Description: Thiele - Engdahl, Inc. uses printing inks.
In equipment cleanup the company uses isopropyl acetate.
Courses of Action
Thiele-Engdahl uses solvent twice for cleanup before
recovery and reuse. The solvent is recovered on-site
using batch distillation. Distillation bottoms are sent
off-site for disposal.
Savings:
Before the distillation system the company sent 5,000
gallons of used solvent to off-site disposal every 45 days.
Since reclaiming and reuse reduce both the volume of waste
and the volume of virgin solvents purchased, significant
savings result, paying for the distillation system in 2
years.
