Frequently asked questions

What counts as household hazardous waste?

Items that are flammable, corrosive, reactive, or toxic in normal household quantities — things like old paint, batteries, chemicals, and fluorescent bulbs are common examples.

Can I just throw a small amount away?

It depends on the specific item and condition — some items are trash-safe once in a certain state (like fully dried latex paint), while others never belong in regular trash regardless of quantity.

Is the rule the same in every state?

Federal law sets a general floor, but some states are stricter for specific items like batteries. Check our state-level notes for anything state-specific we've flagged.

What if I have a large quantity to get rid of?

Larger quantities more often need a scheduled household hazardous waste collection event or facility drop-off rather than routine curbside options — check your local program.

This is general educational guidance, not a substitute for your local waste authority's specific rules. When in doubt, contact your local household hazardous waste program.
