Why can't oil-based paint go in the trash?

Oil-based paint is classified as hazardous waste because it contains flammable solvents, heavy metals, and chemicals that can contaminate groundwater. It must be taken to a household hazardous waste facility for proper treatment.

Same PaintCare program as latex — oil-based paint, stains, varnish, shellac all accepted free at 60+ metro drop-off sites since July 2015.

Useful local details

Denver County has no large permanent HHW facility of its own; the City refers most heavy HHW to Rooney Road Recycling Center in Jefferson County (151 South Rooney Road, Golden) or to Veolia in Henderson (Adams County). Eligibility and fees depend on whether your jurisdiction is a paying participant.
Rooney Road runs Wed and Sat by appointment only (303-316-6262). Latex/oil paint and used motor oil are free drop-offs. Curbside pickup is available for residents physically unable to drive ($40 co-pay).
Denver Recycles weekly compost cart service is bundled into the PAYT fee citywide as of 2023 — one of the few US cities to make residential composting universal at no extra charge.
Denver Treecycle: free Christmas tree drop-off in early January; trees are mulched and the mulch is given back to residents free at the May Mulch Giveaway & Compost Sale. Trees left for regular trash pickup are NOT composted.
Best Buy in metro Denver still charges $29.99 to recycle CRT TVs/monitors (flat-panels free), reflecting the high handling cost of leaded glass after the e-waste ban.

Colorado is one of only a few states with a PaintCare program that offers free household door-to-door pickup for 10+ gallons, not just drop-off sites.
Denver's 'Waste No More' ordinance (voter-approved 2022) enforcement was delayed to September 2026, giving multifamily and commercial buildings extra time to comply with mandatory recycling and composting requirements.
