5 Things You Should Never Throw in a Dumpster (Louisville KY Guide)
May 2026 · 4 min read
Dumpsters are convenient — but some items can cause safety issues, fines, or environmental damage if they're tossed like regular trash. If you're cleaning out a house, doing a remodel, or managing a property in the Louisville area, here are five common things you should not throw in a dumpster — plus what to do instead.
1) Paint, stains, and chemicals
Liquid paint, solvents, pool chemicals, pesticides, and cleaning chemicals can leak, react, or contaminate loads.
Better options
- ✓Keep lids tight and store upright until you have a proper drop-off option
- ✓Ask your local waste program about household hazardous waste days
- ✓For latex paint: some programs allow drying it out fully before disposal (rules vary)
2) Batteries (especially lithium)
Lithium batteries (tool batteries, laptop batteries, e-bike/scooter batteries, power banks) are a major fire risk. They can get crushed in a dumpster or truck and ignite.
Better options
- ✓Tape the terminals and store in a non-metal container
- ✓Use battery recycling drop-offs (many retailers offer them)
3) Electronics (TVs, computers, printers)
E-waste often contains materials that should not go to the landfill. Plus, dumping electronics can create compliance issues for property managers and contractors.
Better options
- ✓Use an e-waste recycling program
- ✓Donate working items when possible
- ✓If you're unsure, separate it from the rest of the debris so it can be handled correctly
4) Tires and automotive fluids
Tires, oil, coolant, transmission fluid, and fuel do not belong in a dumpster. Tires can be rejected at the landfill, and fluids can leak and contaminate everything.
Better options
- ✓Take tires to a tire shop or recycling program
- ✓Take fluids to an auto parts store or approved disposal site
5) “Mystery” hazardous materials (and anything with a warning label)
If you do not know what it is — or it has a hazard label — do not toss it in a dumpster. This includes unknown powders, unlabeled jugs, old shop chemicals, and certain construction materials.
Better options
- ✓Set it aside and keep it sealed
- ✓Take clear photos and ask a pro what it is before moving it
Quick rule of thumb
If it can leak, ignite, explode, or has a warning label, it should not go in a dumpster.
