P2 Application:

1

Environmental Benefits:

Spent ion exchange resin is listed on the company's NOR as a Class I nonhazardous waste, requiring manifested disposal in either a Class I secured landfill, or incineration. In addition, manifested disposal amounts must be reported on the company's annual waste summary. The total amount of spent resin was 434 ft3, or 26,350 lbs., in sixty-two 55-gal drums. Incineration by-products potentially produced would include carbon monoxide, styrene, and divinylbenzene. Although generally considered to be inert, it is possible that heavy metals retained by the resin over its life expectancy could cause a potential leachate problem in a landfill as it decomposed. Once the resin has been totally expended, it may be processed and reclaimed for its polymer value in the manufacture of other plastics or resins.
