PRINCETON — Princeton officials are concerned about dumping violations at the city’s recycling center.

At this week’s meeting of the Princeton City Council, Commissioner Joel Quiram said people have been dropping off non-recyclable items, like prescription drugs, a bathtub, toilet and vanity, drywall, mattresses and paint cans with paint.

To help curtail the unwanted materials, Quiram suggested the council consider having the recycling center open only during daylight hours, instead of the current 24 hours a day, 365 days a year. He also suggested closing off the back entrance and installing fencing and a gate at the front entrance off of North Euclid Avenue. Another recommendation would be to install more security cameras, he said.
