Garbage and Recycling

Residential Garbage Collection

Residential garbage collection in Knowlton Township is arranged by residents through private companies. Most services will provide curbside pickup once a week of up to 100 gallons of household waste. Seniors who have a limited amount of trash are eligible for discounted rates. The names and contact information for garbage collection providers can be found in the local phone book.

New residents should be aware that black bears can become a nuisance when trash cans are left outside for prolonged periods. We advise all residents to keep trash cans in a closed garage or purchase a bear-proof can for outside storage. Bear-proof cans can be purchased through links from the following site


Residents are required by law to recycle and we absolutely encourage every family to recognize the importance of this civic responsibility. Knowlton Township’s solid waste is currently incinerated and the ash is deposited in the Warren County landfill located in White Township. With the landfill expected to reach full capacity in 2021, it is essential that all residents recycle as much waste as possible not only to save natural resources but also to preserve the landfill’s disposal capacity.

Curbside recycling is offered by the same companies that provide garbage collection, usually on a two-week schedule. Knowlton recycles cardboard, glass, metal, plastic, glossy paper, and newspapers, which must be bundled.
