Block Foam

Running in conjunction with the latex paint program is our block foam recycling program. Bring your foam blocks to the Treatment Facility Monday - Saturday, 8 a.m. -2 p.m., and place them in a convenient, covered trailer for transport to the North Aurora DART facility.  Ensure all foam is dry, tape or other attached items are removed. Be sure to try and distinguish fire retardant treated foam (NOT ACCEPTABLE) from regular/untreated block foam. Treated foam typically will bend and not break easily, treated material can also feel as if there is a satin sheen is present. Unfortunately, any blocks with these properties must be disposed of in the trash. Please note packing peanuts are NOT accepted at the site as well. Visit for information on where to recycling packing peanuts and a vast array of other items.

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.
