Improper paint disposal can cause real damage to animals and the environment. Paint poured down a drain carries chemicals that contaminate drinking water and harm aquatic life. Paint dumped on soil seeps into the ground, polluting groundwater. Even old cans stored incorrectly can leak volatile organic compounds into the air inside your home.
Latex paint is one of the most commonly mishandled household items – not out of carelessness, but simply because most people don’t know what the right option looks like. This guide breaks down exactly how to dispose of latex paint responsibly and what paint recycling solutions are available right here in St. Louis.
Why You Shouldn’t Pour Leftover Paint Down the Drain
Paint contains a mix of chemicals, pigments, and in many cases volatile organic compounds (VOCs). When poured down a drain, these substances bypass standard water filtration and make their way into local waterways. The consequences aren’t small:
- Aquatic life is directly affected as chemicals disrupt underwater ecosystems
- Drinking water sources become contaminated, creating long-term public health risks
- Soil quality degrades when paint seeps into the ground through drains or outdoor dumping
- Air quality suffers when VOC-heavy paint is left open or improperly stored indoors
Beyond the environmental impact, improper paint disposal violates local waste management regulations in many Missouri counties – meaning it’s not just an environmental issue, it’s a legal one.
What Type of Paint Can Be Recycled?
Not all paint is handled the same way – and knowing the difference saves a lot of confusion before scheduling a pickup or heading to a collection event.
Latex or water-based paint is the most recyclable type. It’s also the most common paint found in Missouri homes. Paint Busters Recycling accepts:
- Interior and exterior latex paint
- Latex primers
- Water-based stains and sealers
- Partially full or full cans
- Dried latex paint
Oil-based paint is a different story. It contains stronger solvents and chemicals that require a separate disposal process entirely – and is not accepted through this program. The same goes for aerosols and spray cans.
Not sure which type you have? Read the label:
- If it says “clean up with soap and water” – it’s latex paint
- If it says “clean up with mineral spirits or paint thinner” – it’s oil-based paint
How to Dispose of Latex Paint Responsibly

How to Prepare Paint for Safe Disposal ?
Before scheduling a pickup or heading to a collection event, a little preparation goes a long way. Here’s how to get your paint ready for safe and responsible disposal.
Step 1: Check if the Paint Is Still Usable
Open the can and take a look. If the paint stirs back to a smooth, consistent texture and doesn’t have a strong sour smell, it’s likely still usable and qualifies for recycling. Signs that paint is no longer usable:
- Lumpy or stringy texture that won’t stir out
- Strong sour or rotten smell
- Visible mold or separation that won’t blend back
If you’re unsure whether your paint qualifies, the Recycle Paint page breaks down exactly what’s accepted.
Step 2: Let Liquid Paint Dry Completely
If the paint is no longer usable but still liquid, it needs to dry out before disposal. Leave the lid off and place the can in a well-ventilated area away from children and pets. For larger amounts, you can speed up the process by mixing in:
- Cat litter
- A commercial paint hardener
Once fully dried, latex paint can typically be disposed of with regular household trash — though checking local Missouri regulations beforehand is always a good idea.
Step 3: Close and Secure the Paint Can
If the paint is still usable and heading to a pickup or collection event, make sure the lid is sealed tightly and the can is not leaking or damaged. This keeps the paint in good condition during transport and ensures it can move forward through the paint recycling solution process without issues.

Frequently Asked Questions (FAQs)
- Can I recycle paint that has been sitting in my garage for years?
Age alone doesn’t disqualify paint from recycling. Open the can and check — if it stirs back to a smooth consistency without a foul smell, it can still be scheduled for pickup.
- How do I know if my latex paint is still usable before scheduling a pickup?
Paint that blends back to a smooth, consistent texture with no strong sour odor is generally still usable. Lumpy, stringy, or foul-smelling paint has gone bad and is no longer recyclable.
- Can I mix different colors of latex paint together before disposal?
It’s best not to. Mixing colors makes it harder to reformulate paint into a usable product during the recycling process. Keep colors separate and let Paint Busters Recycling handle the sorting.
- Is dried latex paint safe to put in regular household trash in Missouri?
In most Missouri counties, completely dried latex paint can be disposed of with regular household trash. Regulations vary by area, so checking with your local waste management authority beforehand is recommended.
- What happens if I accidentally pour latex paint down the drain?
If you accidentally pour a small amount of latex paint down the drain, do not pour more paint or other chemicals into the drain to flush it away.
