How to Recycle Paint
Latex and oil-based architectural paint, plus primers and single-component finishes. The one hazardous material with a real nationwide take-back program, in the states that have adopted it.
Quick answer
Use PaintCare if you are in one of the 12 states or DC where it operates, since it takes latex and oil-based paint free at retail drop-offs. Outside those, oil-based paint is always household hazardous waste. Latex can often be dried out and binned, but not everywhere: California treats latex as presumed hazardous and prohibits drying it without a treatment permit, so check before you reach for the kitty litter. Before you go, confirm that a local recycling center accepts the material in its current condition.

How to Prepare
- 1Check whether PaintCare operates where you live, because that decides everything else
- 2Keep paint in its original labeled container, since drop-offs need to identify it
- 3Keep lids sealed and separate latex from oil-based
- 4Buy or accept leftover paint from neighbours before treating any of it as waste
- 5Where drying latex is permitted, use an absorbent such as cat litter or a hardener and let it solidify fully before binning
- 6Do not dry out latex paint in California, where it is presumed hazardous and drying without a permit is prohibited
- 7Never pour any paint down a drain, on the ground, or into a storm drain
- 8Treat pre-1978 paint as potentially lead-bearing and do not sand or burn it
Where to Recycle
- PaintCare drop-off sites at participating paint retailers, in 12 states and DC
- Household hazardous waste facilities and collection events
- Municipal reuse and paint-swap programs
- Community groups, theatre companies, and habitat organizations that take usable leftovers
Special Instructions
PaintCare runs in 12 states plus the District of Columbia, funded by a fee added when you buy paint, with drop-off at participating retailers. It takes latex and oil-based architectural paint, primers, stains, shellacs, lacquers, varnishes, and urethanes in single-component form. It does not take aerosols, paint thinners and solvents, two-component products, or industrial coatings. Outside those jurisdictions, oil-based paint goes to household hazardous waste. Guidance on latex splits by state. Most agencies treat dried latex as ordinary trash and publish drying methods graded by volume, but California does not: CalRecycle treats latex paint as presumed hazardous and states that intentionally drying paint without a permit to treat hazardous waste is prohibited. That makes the popular kitty-litter advice illegal in the largest state, so check your own rules before following it.
Environmental Impact
Paint is the hazardous product most likely to sit unused in a garage, and the least necessary to throw away at all. Leftover architectural paint in usable condition is wanted by community groups, theatre sets, and neighbours, and PaintCare states remanufacture recovered latex into new paint. Solvent-based paint contributes volatile organic compounds and contaminates soil and groundwater when poured out, which is why every jurisdiction treats it as hazardous waste regardless of quantity. Pre-1978 paint is a separate hazard: lead paint is why sanding, scraping, and burning old finishes require containment rather than ordinary care.

FAQs
How do I dispose of leftover paint?
Use PaintCare if you are in one of the 12 states or DC where it operates, since it takes both latex and oil-based paint free at retail drop-off points. Outside those states, treat oil-based paint as household hazardous waste.
Can I throw latex paint in the trash?
Often yes once it is fully dried out, but not everywhere. California treats latex as presumed hazardous and prohibits drying it without a treatment permit, so check your local rule before you reach for the kitty litter.
Is oil-based paint hazardous waste?
Yes. Outside a PaintCare state it is always household hazardous waste and needs a proper HHW drop-off. It should never go in the trash, down a drain, or onto the ground.
How do I dry out latex paint?
Where it is permitted, mix in an absorbent such as cat litter or a commercial paint hardener and leave the lid off until solid. This works for small amounts; a large volume is better taken to a drop-off.
Can I recycle empty paint cans?
Metal cans that are completely dry and free of residue are usually accepted as scrap metal, and some curbside programs take them. Rules vary, so confirm locally rather than assuming.
What about spray paint and aerosols?
Those follow a different route. Pressurized cans are handled as their own hazardous stream rather than with liquid paint, so take them to a household hazardous waste program.
