Conservation Center

The Town of Westfield has operated the Westfield Conservation Center for over thirty years. The Center is classified by the State of New Jersey as a transfer facility for organic waste and recyclable materials. As such, the Center serves as a staging area until the materials can be transported to a subsequent facility for proper disposal or disposition. Residents may dispose of "biodegradable organic waste material of plant origin produced on Westfield premises" at the Conservation Center. For those residents who chose to use the Center for such a purpose, the Town charges an annual flat fee of $60 to offset its costs.

For curbside recycling information, please visit the Curbside Recycling section. Seasonal leaf collection information can be found in the Public Works section.

Information for Landscape Contractors

Landscape and lawn service contractors that provide service to Westfield residents may choose to register with the Town of Westfield in order to obtain a permit(s) that allows entrance to the Westfield Conservation Center to:

  • Purchase wood chips and mulch at a cost of $15 per cubic yard, subject to availability.
  • Purchase logs and firewood at a cost of $125 per cord or $75 per half cord, subject to availability.


Landscape contractors choosing to register must do so in person at the Department of Public Works' office, 959 N Avenue W, between the hours of 9:00AM and 3:00PM and present a client list as proof of service to Westfield residents. All payments must be made at the time of purchase or at the time of disposal, whichever applies, and must be made by check or money order payable to the "Town of Westfield" in the exact amount due. Purchase of materials and disposal of leaves is on a first-come, first-serve basis.


Landscaper and lawn service contractors who decide to register with the Town of Westfield and obtain a permit may only use the Center for purchasing wood chips, logs and firewood and to dispose of residents' leaves. It does not permit landscapers and lawn service contractors to deposit grass clippings or other organic debris at the Center. 

This optional registration for landscapers to utilize the Conservation Center has been in place since 2017, and is separate from the registration to conduct landscaping and tree removal business in Town addressed in General Ordinance No. 2212 (adopted April 6, 2021). As noted in the ordinance, those businesses that are registered to utilize the Conservation Center for leaf deposits and mulch/firewood purchases will have the $50 fee from the new ordinance waived.
