How to Handle Hazardous Waste
Renting a dumpster is one of the smartest moves you can make when tackling a big cleanout or home renovation. While convenient for easy removal of debris, furniture, junk, or garbage, a dumpster rental is not a free-for-all. Some material cannot go in—and that’s not us being picky. It’s about what is safe and legal.
One of the biggest unacceptable material types? Household hazardous waste. This blog will walk you through what it is, why it matters, and how to dispose of it properly.
What is Hazardous Waste?
Hazardous waste is anything that poses a threat to people, property, or the environment. It includes materials that are toxic, flammable, corrosive, poisonous, or contain heavy metals.
Here are some of the usual suspects you might find in your garage, basement, or under the sink:
- Paints & Solvents: Oil-based paints, varnishes, and thinners are flammable and contain harmful chemicals.
- Cleaning Chemicals: Bleach, ammonia, and drain cleaners can be reactive and dangerous when mixed.
- Pesticides & Herbicide: These contain toxic substances that can leach into the soil or water supply, harming plants, animals, and humans.
- Automotive Fluids: Oil, antifreeze, and brake fluid are flammable and toxic to wildlife and waterways.
- Batteries (Car & Household): Batteries contain heavy metals like lead, mercury, and cadmium.
- Electronics: TVs, monitors, and devices can leach hazardous metals if crushed or burned.
These materials, and others like them, can harm the environment, expose sanitation workers to risk, cause fires or explosions, and contaminate water.
