DuPont desires to find a new way to reuse or dispose of its waste tetrahydrofurran (THF). As of now, the THF is shipped out after one use in the polymerization process; this is a large
waste of a costly chemical. DuPont is actively searching for a company that could reuse or recycle the THF.
Waste THF - Upwards of $189,000. The first option is to send the non-contaminated THF
to Nova Molecular to be cleaned. Cleaning one-fifth of the total THF stream saves $400 per
year in disposal costs. Reuse of the reclaimed THF at the DuPont plant would save an additional
$172,700 per year in purchasing costs. The second option is to send the contaminated THF to
BFC Gas and Electric Companies to be used to generate electricity in Ankeny. All of the THF
could be processed at BFC.
