Drop grass clippings off in the compost bin or consider mulching them! The bin is located south of the main entrance of the IMC, (126th Ave. & Ogden St.) just outside of the interior gate. Be prepared to open all bags on site.

Just because you think something is recyclable at the curb doesn't mean it is. Common items such as plastic bags and shredded paper can contaminate eligible materials. Check out the Waste Wizard on the free City of Thornton Recycles mobile app if you are unsure! https://www.ThorntonCO.gov/TrashRecycling
