Foam Block Packaging

During the  2017 latex paint recycling, DuPage County is collecting and recycling foam block packaging. This program will collect expanded polystyrene (EPS), commonly referred to as foam, block packaging. The blocks will be amassed in an onsite trailer and then will be transported to the North Aurora DART Facility at 310 Evergreen Drive. The packaging will be deposited into their public, 24 hour recycling drop-off. Although we do not accept food service items they can be recycled at the DART facility listed above.

Please ensure that all block packaging is clean, dry with no tape or other adhesive products remaining on it. Prior to drop off check to ensure the product does not contain additional chemical additives such as fire retardants. This can be done by breaking off a piece of the foam packaging. If packaging breaks cleanly with little resistance it can be recycled through the DuPage County program. If there is resistance or bending of the product this would indicated the foam as been chemically altered and must be placed in the trash for local pick-up. 

Packing Peanuts - Packing peanuts, bubble wrap and other loose packaging will not be accepted at this drop-off location. Please refer to the DuPage online recycling guide and select bubble wrap from the drop down menu to find acceptable recycling locations for this material. 

Latex Paint

DuPage County operates a free latex paint recycling program for residents. Residents can drop off their usable, unwanted latex paint during the designated summer collection dates listed above free of charge.  Paint is not allowed to be dropped off during non-operation hours and days. 

The site is NOT able to accept paint that has been:

  • Frozen (paint left in an unheated garage may result in frozen paint)
  • Is greater than 10 years old or
  • Paint that has been mixed with other products
  • Oil based, a thinner, stain or varnish. These products must be disposed of at the Naperville Regional Household Hazardous Waste Facility.

Residents are able to pick up free recycled latex paint from this program beginning June 5th or as available. The paint is filtered and re-blended into a variety of colors, types and finishes. Availability of specific paint types, colors and finishes varies upon what is collected. Paint will be available in 5- gallon containers and provided on a first come, first served bases. Paint will be available until supplies runs out. No warranty expressed or implied, accompanies the recycled paint.

Cooking Oil

Used cooking oil should not be poured down sink or pipe drains. Oil and grease will stick to pipes in small particles eventually creating blockages preventing sewage lines from draining correctly. To prevent this, there are multiple sites across DuPage County that accept cooking oil. In 2016 the Woodridge facility began an additional collection to those already operating to dispose of their liquid cooking oil. Located at the site of the latex paint collection, a container has been provided for residents to dispose of their cooking oil. This container is not able to accept animal or other solid fats, motor oil or any other type of non-cooking oil. Residents are asked to retain their container.  


The collected cooking oil and grease are picked up by a recycling company that transfers it to a processing facility. At the facility, the lipids are separated from the water in the liquid. The lipids are shipped to suppliers to be made into bio-diesel fuel, soap, de-greasers, cleaning products and other items. The water from the liquid is used as a fertilizer in agriculture due to it's high concentrations of nitrogen and potassium.
