That is what my daughter asked me as we traveled on Route 5 in Wallingford, CT next to the Toelles Road railroad crossing. She was referring to the dramatic structure formally known as Cytec Industries, now international Allnex Coating Resins Company. The plant manufacturers coating resins and additives for architectural, industrial, and automotive applications and employs approximately 150 people. The Wallingford facility recently celebrated it's 75th anniversary.
The chemical plant produces innovative materials such as UV(Ultra Violet)/EB (Electron beam) resin which is utilized in many day to day products that you likely own, such cell phones canned soup and Budweiser canned beer. With the use of chemicals required for production of such coatings and resins, certainly the plant is required to closely monitor permitted process wastewater discharge, which empties to the Quinnipiac River.
What do the two large white tanks store?
I am not sure, but the tanks may store powdered raw production material which is delivered via adjacent railway. What an interesting looking plant- I'd love a tour!
