Recycling in Princeton

Princeton's recycling is handled by the Mercer County Improvement Authority. If your recycling is missed or collection was incomplete, you must report it online or call Mercer County Improvement Authority at 609-278-8086.

Mercer County will be enforcing recycling contamination by tagging bins that contain contaminants. They will be tagged with a red "Recycling Rejection Notice". If your bin is tagged, please bring it in and remove the contaminants for the next scheduled recycling day.
