The Flagstaff Hazardous Products Center (HPC) is one of the most valuable — and most misunderstood — waste resources in Northern Arizona. Knowing what it will and won’t take saves you a wasted trip out to the landfill road, and it helps you figure out which items AZ Haul can simply haul away for you instead. Here’s a plain-English guide for Flagstaff residents.
What Is the Hazardous Products Center?
The HPC is a permanent City of Flagstaff facility that gives City and Coconino County residents a safe place to drop off household hazardous waste for free. It diverts more than 200 tons of hazardous, universal, and electronic waste from the Cinder Lake Landfill every year — keeping some genuinely nasty stuff out of the ground and out of the water supply. It’s located on East Landfill Road, and drop-off hours are typically Monday, Wednesday, and Friday.
Who Can Use It
The free drop-off is for City of Flagstaff and Coconino County residents only. To use it, you’ll generally need an Arizona driver’s license or state ID showing your current address, and City residents may also need a current City of Flagstaff water bill (or two pieces of current mail) to verify residency. Business waste is handled separately, by appointment — and at the time of writing that business program is temporarily paused.
What the HPC Accepts
The HPC is built for the hazardous, universal, and electronic waste that should never go in your curbside trash, including things like paints and solvents, automotive and household chemicals, pesticides, batteries, fluorescent bulbs, aerosols, and electronics. The City’s Where to Take Waste chart is the authoritative list, so check it for the specific item you have in hand.
Important Limits to Know Before You Go
A few rules trip people up, so plan around them:
- The maximum allowable container size is 5 gallons.
- There is a 20-gallon waste limit per household, per day.
- Drums, totes, and tanks are not accepted.
- Larger amounts of residential waste require an appointment.
- Keep products in their original, labeled containers and transport them upright and secured so nothing spills.
The HPC also reserves the right to refuse any load that doesn’t meet its guidelines, so it’s worth getting this right before you load up the car.
What the HPC Won’t Take — and What to Do Instead
The HPC is not a general junk facility. It won’t take your old furniture, mattresses, appliances, construction debris, yard waste, or the everyday clutter from a garage or cleanout — and it caps how much hazardous material you can bring at once. That’s where AZ Haul comes in. We handle all the non-hazardous bulky junk the HPC turns away:
- Appliance & furniture removal
- Estate & garage cleanouts
- Construction debris removal
- Yard debris removal
The Simple Rule of Thumb
If it’s a chemical, a battery, a bulb, or an electronic — it likely belongs at the HPC (within the size and volume limits above). If it’s bulky household junk — furniture, appliances, debris, general clutter — AZ Haul can haul it away without you lifting a thing or making the drive. When you’re not sure how something is classified, call the HPC at (928) 213-2159.
Frequently Asked Questions
Does the HPC cost money?
No — drop-off is free for eligible City of Flagstaff and Coconino County residents who bring the required ID and proof of residency.
Can I bring a 55-gallon drum of old chemicals?
No. Containers must be 5 gallons or smaller, and drums, totes, and tanks are not accepted. There’s also a 20-gallon-per-household-per-day limit.
What do I do with old furniture or a broken appliance?
Those aren’t hazardous waste, so the HPC won’t take them. AZ Haul can pick them up and haul them off for you — just request a quote.
