Top 10 Household Items That Must Be Disposed of as Hazardous Waste

When it comes to disposing of the waste from households, people generally collect all the garbage together and throw it into the bins or landfills. Most people think that household waste is normal, and hazardous waste only belongs in big factories or medical labs.

But the fact is that your home is full of items that qualify as household hazardous waste (HHW). Many studies state that lots of leftover household products that contain corrosive, toxic, ignitable, or reactive ingredients are hazardous.

Now, you must be wondering, “How do I recognize an HHW and what to do with it?” The good thing is that you don’t need a chemical-engineering degree to understand what’s safe, what’s risky, and how to dispose of these items properly.

This blog talks about the most common household items you should never just toss in the trash.

Why Is Proper Household Hazardous Waste Disposal So Important?

A hazardous waste is a substance with properties that make it capable of harming human health or the environment. Household hazardous waste includes many everyday products that remain hazardous when they are discarded.

What Happens If You Dispose Of Them Incorrectly?

• Pouring leftover paint thinner, motor oil, or solvents down the drain, into the ground, or into storm sewers can contaminate water supplies, harm septic tanks, or pollute wastewater systems. (Source)
• Leaving chemicals mixed together or storing them in food containers can lead to leaks, spills, fires, explosions, or harmful reactions. (Source)
• Sanitation workers, children, and pets can all be at risk if hazardous items are thrown in with the normal trash. (Source)

The Benefit of Proper Disposal

By disposing of HHW correctly, you protect your family, your community, and the environment. Proper hazardous waste disposal also keeps you compliant with local environmental laws. 

For example, if you live in Reno, there are specific programs and collection sites like Hero Environmental Services designed to handle such waste responsibly, keep the community clean, and avoid potential fines or issues.

Pesticides & Herbicides	Poisonous to humans, pets, and wildlife.	Don’t pour into drains or soil. Drop off at HHW events or facilities.

How to Dispose Of (HHW) Household Hazardous Waste in Reno?

If you’re in or near Reno, here’s how to safely take care of disposal.

• Find your local HHW collection program. Many counties run drop-off events or permanent sites. They accept items listed above.
• Keep items in original containers with labels. This helps handlers know exactly what they’re dealing with.
• Do not mix different hazardous products. For example, don’t pour old paint into aerosol cans or mix solvents and cleaners.
• Pack such wastes in sealed boxes, upright, in your vehicle to avoid leaks and safe transportation.
• Always check local regulations. While federal law may exempt households from full “hazardous waste” regulation, many states/localities have special rules.
• Ask questions before hiring a waste disposal team - “Is this accepted at your drop-off?” “Do I need an appointment?” “Any fees or restrictions?”

Hero Environmental Services is the most trusted company for safe and compliant HHW disposal in Reno.

Commonly Asked Questions About HHW Disposal

Can I just throw old paint in the trash if the can is less than half-full?

In many places, no, especially if it’s oil-based paint or contains solvents. Even if it seems small, it may still be flammable or toxic. Better to treat it as HHW and drop it off.

If the battery is “dead,” can I just throw it away?

It’s best not to. Even dead batteries can leak harmful chemicals or cause fires. Take them to a battery recycling drop-off or your local hazardous waste center instead.

What about latex paint? Is that hazardous?

Many municipalities allow latex paint to be treated differently. For example, dry out the paint, then discard it, but you must check your local rules for areas like Reno/Carson.

If you live in Reno, you can also contact Hero Environmental Services to clear any doubts.

What if I accidentally mixed two chemicals and they reacted?

That’s risky, and you need to call your local fire department or hazardous materials team immediately. Don’t transport unstable mixtures yourself. Mixing can change the disposal category and may require special handling.
