Toxicity Prevention & Chemical Disposal
Household Hazardous Waste (HHW) Guide
Every household collects harsh chemicals over time: weed killers, motor oil, pool acids, and propane cylinders. None of these belong in your regular garbage cart. Learn how to transport and dispose of them safely.
Household Hazardous Waste includes automotive fluids (motor oil, antifreeze), lawn chemicals (herbicides, pesticides, fertilizers), pool chemicals (chlorine, muriatic acid), flammable solvents, mercury thermostats, and small propane cylinders.
Never pour chemicals down drains or place them into household trash bins. Compactor blades rupture containers, causing chemical reactions, chlorine gas clouds, and explosive flashes that endanger sanitation workers.
Keep materials in their original labeled containers with tight caps. Place containers upright inside sturdy cardboard boxes or plastic totes lined with newspaper to prevent spills in your vehicle during transport.
You do not always have to wait for county drop-off days. Major auto parts stores (AutoZone, Advance Auto, O’Reilly) accept up to 5 gallons of used motor oil and car batteries free of charge year-round.
1. Keep all liquids in original containers with readable labels. Never mix different products.
2. Place upright inside a shallow cardboard box or plastic storage bin so bottles cannot tip over.
3. Transport in your vehicle trunk or truck bed, never on passenger seats, with windows cracked for ventilation.
Frequently Asked Questions
How do I find a household hazardous waste drop-off near me?▼
County solid waste management authorities operate permanent HHW collection facilities or host free quarterly community drop-off events at fairgrounds or public works yards.
Can you dispose of small green 1-lb propane camping tanks in trash?▼
No. Camping propane tanks contain pressurized residual gas that explodes inside collection compactor trucks. Take them to HHW facilities or participating propane exchange stations.
Is there a fee to drop off household chemicals at county HHW events?▼
Almost all county and municipal HHW collection programs are completely free for local residential households funded through municipal utility fees or tax assessments.
What happens if you mix different leftover chemicals together?▼
Never mix leftover chemicals. Combining common products like bleach and ammonia produces toxic chloramine gas. Always leave products in original containers.
