Business Hazardous Waste

Household Hazardous Waste Station Banner image

Hazardous waste can have extreme impacts on human health and safety and the environment when placed into curbside collection containers. We facilitate environmentally safe and cost-effective appointments for businesses or non-profit organizations that generate small quantities of hazardous waste through the Very Small Quantity Generator (VSQG) program. Dispose responsibly with us — we make it easy to do the right thing!

It is illegal to dispose of hazardous waste in the garbage, down the drain, or by abandonment

How To Drop Off

How To Drop Off Category Banner image

Qualified businesses and non-profit organizations may be eligible to drop off hazardous waste as part of the City of Palo Alto’s Very Small Quantity Generator (VSQG) program. Please follow these steps to confirm eligibility and participate in the program.

Step 1.Confirm your business’s VSQG program eligibility*

- Must be a business or non-profit organization (painting contractors, photo labs, machine shops, dental offices, retail stores, etc.)
- Must generate 220 lbs. or less of hazardous waste per month (or 2.2 lbs. or less of extremely hazardous waste)
- Must be located in Palo Alto, East Palo Alto, Mountain View, Stanford, Los Altos, or Los Altos Hills.
*Hazardous waste generator status is self-determined based on monthly hazardous waste generation. Businesses that generate more than 220 lbs. of hazardous waste or 2.2 lbs. of extremely hazardous waste in any given month are not considered a VSQG and must comply with the State's regulatory requirements for their appropriate generator status.

Step 2.Fill out an inventory form

Complete an Inventory Form(PDF, 138KB). This allows the City’s disposal contractor, Clean Harbors, to generate an accurate cost estimate for the hazardous waste your business wants to drop off.

Step 3.Obtain a Hazardous Waste Identification Number

If you do not already have a Hazardous Waste Identification number, review the State Department of Toxic Substances Control's (DTSC) website to obtain one.

Step 4.Contact Clean Harbors

Call or email Clean Harbors to submit your completed inventory form and receive a cost estimate and credit card authorization form.

Step 5.Schedule your drop-off appointment and pay

After reviewing the cost estimate, schedule a drop-off appointment with Clean Harbors and pay your associated disposal fees. Appointments are typically scheduled on Saturdays following the residential HHW drop-off hours at 11 a.m.

Arrive promptly for your appointment with the required documentation and appropriate records. All waste should be secured in your vehicle to prevent spills during transportation and be accessible to the technicians who will remove the waste from your vehicle.

Reduce Hazardous Waste

Use less toxic/hazardous alternatives whenever you can and only purchase those toxic/hazardous products in small quantities and use them to completion. Find tips below to help you reduce the amount of hazardous chemicals you have in your business and the amount of hazardous waste you produce!


DIY less-toxic cleaners

Zero out hazardous waste and packaging from common household cleaner products in disposable bottles. Using low-cost natural ingredients, you can mix your own, save money, reduce toxics, and store them in reusable spray bottles or jars! Download a printable version of DIY non-toxic cleaner recipes(PDF, 1MB).

All-purpose cleaner recipe

1 tbsp. white vinegar + ½ tsp. borax + ½ tsp. baking soda + ½ tbsp. castile soap + 2 cups hot water

Add the first four ingredients into a spray bottle, then slowly add the hot water and shake until the dry ingredients are dissolved

Scrubbing powder recipe

½ cup baking soda + ½ cup salt + ½ cup borax powder 

Lightly wet surface with water or undiluted white vinegar (for really bad messes). Sprinkle powder on and let sit 5 minutes. Scrub with a sturdy brush until clean. Rinse with water or vinegar (for really bad messes)

Glass cleaner recipe

1 cup white vinegar + 1 cup rubbing alcohol + 2 cups water

Mix the ingredients in a spray bottle and use to clean glass and mirror surfaces

DIY Non-Toxic Cleaners

Purchase rechargeable batteries instead of single-use

Rechargeable batteries can be charged and reused hundreds and sometimes thousands of times. If batteries must be used, consider purchasing rechargeable to cut down on single-use hazardous waste!

Rechargeable Batteries

Use a drain snake instead of drain cleaner

Got a tough drain clog? Use a metal snake instead of a caustic drain cleaner. The impact on the waterways and water treatment plant will be greatly reduced and you won't have any hazardous waste to dispose of!

Transportation Requirements

  • All waste containers should be properly secured in your vehicle to avoid falling over and spilling.
  • Any leaking containers should be properly contained. Leaking containers can be placed into an unbroken clean container and secured with a lid.
  • A plastic garbage bag can be used to keep odors contained during transportation to the Household Hazardous Waste Station.
  • Keep your vehicle’s carpet or upholstery clean by putting down plastic or cardboard.

State Law prohibits the transportation of more than 15 gallons or 125 pounds of hazardous waste without a State hazardous waste hauler permit (HSC 25218.5.1). The law helps keep you and the roads safe from potential spills and chemical releases.
