Princeton, NJ created a curbside organic waste program
Complete
The city created this Curbside Waste Program to reduce the food/organic waste in its landfills by utilizing behavioral science to increase the composting rate among residents. The city identified guilt, not rewards, as the residents' key motivator for composting.
Room for Improvement
The program was suspended due to operational difficulties. The contractor occasionally took the waste to the incinerator, not the farm as directed. The city is now exploring using municipal staff to pick up the food waste instead of a contractor. Despite the identification of guilt a a key motivator, residents still found it difficult to change their composting behaviors.
