When most people think about renting a dumpster, they picture tossing out old furniture, construction debris, or piles of clutter from a home remodel. And while redbox+ Dumpsters of St. Louis makes it easy to handle all those types of waste, not everything can—or should—go into a roll-off dumpster. Disposing of the wrong items can lead to fines, environmental hazards, or even damage to the dumpster itself.
If you’re planning a cleanout, renovation, or landscaping project in St. Louis, it’s important to know what materials are prohibited. Doing so helps you avoid unnecessary stress, ensures your project runs smoothly, and protects both the environment and your community.
Why Some Items Can’t Go in a Dumpster
Dumpster services like redbox+ must comply with local, state, and federal regulations regarding waste disposal. Certain materials are considered hazardous, toxic, or otherwise unsafe for landfill disposal. Other items may damage the dumpster, create fire hazards, or contaminate other trash.
For homeowners, the key takeaway is simple: not everything you want to throw away can go into a roll-off container. Knowing the restrictions ahead of time saves you time, money, and potential headaches.
Common Items You Should NOT Put in a Dumpster
Here’s a detailed list of items St. Louis homeowners should avoid putting in their redbox+ dumpster:
1. Hazardous Household Chemicals
Many household products contain chemicals that are dangerous to humans, animals, and the environment if disposed of improperly. These include:
-
Paints, stains, and varnishes
-
Solvents and thinners
-
Pool chemicals and chlorine
-
Pesticides, herbicides, and insecticides
-
Gasoline, kerosene, or diesel
Disposing of these substances in a dumpster can cause fires or chemical reactions. Instead, take them to a certified hazardous waste facility. St. Louis residents can contact the city’s Household Hazardous Waste (HHW) collection program for safe disposal options.
2. Flammable or Explosive Materials
Items that can ignite or explode under certain conditions should never go into a dumpster. This category includes:
-
Propane tanks or cylinders
-
Fireworks
-
Ammunition or gunpowder
-
Pressurized gas canisters
Even seemingly empty containers can be dangerous. A dumpster filled with flammable items is a serious fire risk, not only to your property but also to the dumpster company and surrounding neighborhood.
3. Tires
Tires are bulky, non-biodegradable, and difficult to dispose of safely. Dumpsters are not designed to handle large numbers of tires, which can trap water, create mosquito breeding grounds, or lead to improper landfill practices. Many tire shops in St. Louis offer recycling programs for old tires, so check with local providers before tossing them out.
4. Electronics (E-Waste)
Old electronics contain hazardous metals like lead, mercury, and cadmium. These include:
-
Computers and laptops
-
Televisions
-
Printers
-
Monitors
-
Microwaves
Electronics should be recycled through certified e-waste programs. St. Louis has several options for electronic recycling, including special drop-off events and local recycling centers.
5. Batteries
Car batteries, lithium-ion batteries, and rechargeable batteries are all considered hazardous waste. They can leak chemicals or even explode under heat and pressure. Batteries should be taken to specialized recycling locations rather than placed in a dumpster.
6. Medical Waste or Biohazards
Materials such as sharps, needles, syringes, or medical waste are strictly prohibited. Biohazardous items require special handling to prevent injury or contamination. Local St. Louis hospitals, pharmacies, or clinics may offer safe disposal options for these items.
7. Asbestos-Containing Materials
Older homes in the St. Louis area may have asbestos-containing insulation, siding, or flooring. Asbestos is highly toxic when inhaled and must be handled by licensed professionals. Never attempt to dispose of asbestos in a standard dumpster.
8. Large Quantities of Concrete, Bricks, or Dirt Without Permission
While small amounts of concrete or dirt are often acceptable in certain dumpster sizes, large volumes can be extremely heavy and exceed weight limits. This can cause the dumpster to sag, damage the truck during transport, or result in additional fees. Always check with redbox+ before placing heavy materials in your container.
9. Refrigerators or Appliances with Freon
Older refrigerators, freezers, or air conditioning units often contain Freon or other refrigerants, which are harmful to the environment. These appliances require certified removal and cannot be disposed of in standard dumpsters.
10. Liquids of Any Kind
Pouring liquids—paint, oil, cleaning solutions, or water-soaked debris—into a dumpster can create hazards, promote mold growth, or leak onto the ground. Only dry materials should go in a roll-off container unless redbox+ explicitly approves otherwise.
