Latex paint (water-based) in a solidified form is not hazardous waste, so you can throw it in the trash but not in wet condition. You have to prepare it properly for throwing it away.
To throw it properly, divide the paint into small amounts, add kitty litter, sand, or shredded newspaper, then mix it well. You need to leave the lid off and allow all particles to completely dry. After that, you can throw away dried latex paints.
Putting them directly into the trash is not a good practice. Many garbage collectors have the waste segregation process where solid waste, liquid waste, and recyclable products are picked differently.
In that case, the latex paint thrown into the trash can create a problem for the garbage collector centers. Because the paint will not allow them to segregate the waste properly.
Therefore, it is always advisable to dispose of the latex paint properly before throwing it away in the trash.
Can I Throw Away Old Latex Paint?
Yes, you can throw away old latex paint, but only if the paint is completely dry. If your leftover paint is not very old and still wet, then throwing it away is not a good idea.

Can You Pour Latex Paint Down The Drain?
Although latex paint is safe to use while it’s still wet, you should never pour leftover latex down the drain. Paint fumes are highly flammable and dangerous. If they’re released into your house, then your home can catch fire.

If, by any chance, you are thinking of throwing it away or pouring the latex paint into a city or storm drain, then please restrain your thoughts. It would be best to never throw the latex paint into the city or storm drain because it can effortlessly leak or leech into the water supply.

The best practice to follow is to dispose of the latex paint safely. Or, check whether your city has any disposal centers for chemical-based products. If your city has a disposal center for the chemical products, you must take your remaining latex paint there to be disposed of properly.
