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 www.state.nj.us/dep/fgw/bearcont.htm.

Recycling

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. 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.

AVOID THE SPARK

There are hidden dangers tied to improper handling and disposal of batteries at their end-of-life. This has led to an increasing number of fires at recycling centers, waste facilities and in garbage trucks. Learn how to safely manage batteries and find drop-off locations for end-of -life batteries at the “Avoid the Spark – Be Battery Safety Smart” website found at https://batterynetwork.org/safety/avoid-the-spark/

HOUSEHOLD BATTERIES

Batteries should never be put in your recycling cart, bucket, or bin because they are contaminants in the recycling process. Certain rechargeable batteries – lithium batteries, in particular- may combust if damaged and pose a threat to recycling facilities and staff.

Rechargeable batteries include :

Nickel Cadmium (Ni-Cd)

Nickel Metal Hydride (Ni-MH)

Lithium Ion (Li-ion)

Nickel Zinc (Ni-Sn)

Small Sealed Lead (pb)

There is also a collection barrel at the Warren County District Landfill,

Monday thru Friday, 7:00 a.m. – 2:30 p.m., and Saturday 7:00 a.m. – 11:00.

Non-Rechargeable Batteries (alkaline dry cell batteries) such as AA, AAA, C, D, and 9 volt no longer contain mercury or hazardous components and therefore may be disposed of in your regular household trash.

Old American Flags

Flags can be respectfully retired by dropping them off in the Flag drop box located at the Knowlton Municipal Building.

New Jersey Agricultural Recycling Programs

The New Jersey Department of Agriculture has a strong commitment to ensuring compliance with New Jersey’s mandatory recycling regulations The Department has developed and/or facilitated several economic development programs to assist Garden State Farmers to recycle the plastic generated on their farm operations and reduce their solid waste disposal fees. Please contact Department of Agriculture @ (609) 292-5536 or e-mail @Karen.kritz@ag.state.nj.us.

Plastic Nursery Pots, Plug Tray, and Flats

A new opportunity exist that will enable farmers to recycle nursery post, plastic flats, trays and Cell packs. The cost of disposing of HDPE #2 nursery pots weighing 20,000 pounds can be up to $580 at a landfill. Plastic recyclers are looking for these material and offering to pay for the scrap.

Each type of plastic is to be segregated on separate pallets. Most of the plastic has a code stamped on it (#6 keynotes polystyrene, #5 polypropylene, and #2 HDPE) . All plastics, with the same code, regardless of size, style, or color, can be placed on the same pallet. If the type of plastic cannot be identified, misc. items can be placed on a separate pallet with a notation stating – plastic needs to be sorted, Sorted plastics by types will receive a better price.

Some plastics recyclers will generally pick up half or full trailer loads of materials. For shipments of only a few pallets, the plastic recyclers will generally try to combine the pickup with another farmer in the area as a way to fill up the trailer.

In the end, the farmer will save landfill tipping fees which can run upwards of $100 per ton in NJ, they can generate $20-$100 per ton revenues by recycling and they will do their part to help N increase it’s recycling.
