Recycle Cooking Oil
The city of Thornton and Recycoil offer a cooking oil recycling program that is easy to use, environmentally friendly, and is offered year-round. This type of recycling is very important to our community because the recycled oil is used in the production of biofuels, keeping it out of area landfills and Thornton's sewer system.
Residents can drop-off used cooking oil, in one gallon, sealed plastic containers only, at Thornton’s Infrastructure Maintenance Center, 12450 Washington Street, Monday through Friday from 8 a.m. to 5 p.m., excluding major holidays. Please use the front door entrance to the IMC building located just off of Washington Street.
This service is for residents only and cooking oil from businesses and restaurants will not be accepted. Commercial businesses can contact Recycoil at 303-544-1500.
