Under US federal law, waste generated by normal household activities is excluded from the definition of hazardous waste under the Resource Conservation and Recovery Act, so household hazardous waste is regulated by states and local governments instead, and the EPA advises using local collection programs rather than pouring products down drains or putting them in regular trash.

What counts as household hazardous waste

The US Environmental Protection Agency (EPA) considers some leftover household products that can catch fire, react or explode under certain circumstances, or that are corrosive or toxic, to be household hazardous waste (HHW). Examples it gives are paints, cleaners, oils, batteries and pesticides, which can contain hazardous ingredients and need special care at disposal. This guide covers the United States only; the UK, Ireland and Australia have different rules, covered in our guides on sorting household waste in the UK and the NSW Household Chemical CleanOut.

The federal household exclusion

The EPA explains that most hazardous wastes that are ignitable, reactive, corrosive or toxic are regulated under Subtitle C of the Resource Conservation and Recovery Act (RCRA), but that Congress created an exclusion for household waste, found in Title 40 of the Code of Federal Regulations, Part 261.4. Two criteria must both be met: the waste must be generated by individuals on the premises of a temporary or permanent residence, and the waste stream must be composed primarily of materials found in wastes generated by consumers in their homes. The EPA interprets the exclusion to include household-like areas such as campgrounds, picnic grounds, ranger stations and day-use recreation areas.

Who regulates it instead

Although excluded from Subtitle C, the EPA says household hazardous waste is regulated under Subtitle D of RCRA as a solid waste, which means it is regulated at state and local level. It adds that state regulatory requirements for generators may be more stringent than the federal program and that people should check their state’s policies. In practice, what a household is allowed to put in the trash, and where it can take other items, is set by the state, county or city.

How collection programs work

The EPA says many communities have collection programs for HHW to reduce the potential harm. It suggests searching for “household hazardous waste” near a zip code in the Earth 911 database, or contacting the local environmental, health or solid waste agency to find permanent or periodic collections. If a community has no year-round system, the EPA suggests looking for designated collection days at a central location, and if there is neither, dropping certain products at local businesses. It gives the example of local garages that may accept used motor oil for recycling. The agency does not endorse specific services.

Safe handling before disposal

The EPA lists quick tips. Follow the instructions on product labels for use, storage and disposal. Never store hazardous products in food containers; keep them in original containers and never remove labels. If a container is corroding it needs special handling, and the EPA suggests calling local hazardous materials officials or the fire department for instructions. Never mix leftovers of one HHW product with another, because incompatible products might react, ignite or explode, and contaminated HHW may become unrecyclable. Even empty containers can be hazardous because of residual chemicals, so they should be handled with care too. The EPA also publishes separate instructions for disposing of consumer e-cigarettes.

What not to do

According to the EPA, improper disposal of HHW includes pouring it down the drain, on the ground or into storm sewers, or, in some cases, putting it out with regular trash. The dangers might not be obvious, but improper disposal can pollute the environment and threaten human health. Some HHW can injure sanitation workers or contaminate septic tanks or wastewater treatment systems if poured down drains or toilets, and it can also be a hazard to children and pets if left around the house.

Cutting down the amount you have

The EPA also encourages reducing purchases of products with hazardous ingredients and using alternatives, such as a plunger or plumber’s snake instead of drain cleaner, or vinegar or lemon juice in water as a glass cleaner. The EPA’s Safer Choice program provides more ideas. Our guide to leftover paint and household chemicals explains the equivalent issue in the UK.

FAQs

Is household hazardous waste regulated by the federal government?

The EPA says it is excluded from the federal hazardous waste rules under RCRA Subtitle C, but is regulated as a solid waste under Subtitle D at state and local level.

Where can I take paint or pesticides in the US?

The EPA suggests contacting the local environmental, health or solid waste agency about permanent or periodic HHW collections, or searching the Earth 911 database by zip code.

Can I mix leftover chemicals to save containers?

No. The EPA says never to mix HHW with other products, because incompatible products might react, ignite or explode.

Does the exclusion cover a business?

The EPA describes the exclusion as covering waste generated by individuals at a residence or the household-like areas it lists, and notes that state requirements for generators may be more stringent.

The bottom line

In the United States, household hazardous waste falls outside the federal hazardous waste rules and is managed by state and local programs, so the right route depends on the local collection options. The EPA advises keeping products in original containers, never mixing them and using collection programs instead of drains or regular trash. This is general information about US federal guidance; check state and local rules for the exact requirements.
