1. What is Household Hazardous Waste (HHW)?
Products around the home that contain chemicals which are toxic, flammable, corrosive, or reactive are hazardous household products. These products are safe when used and stored following label direction.  However, when the products become unusable and are no longer wanted, they become household hazardous waste. 

2. Who can/cannot participate?
Residents in Saint Louis County, St. Louis City and Jefferson County can participate in the program. The program is for residential households only. Commercial entities and businesses are not permitted to dispose of hazardous wastes at these facilities.

3. What materials are accepted at the facility?
Residentially generated wastes including: paints (oil-based, craft and hobby paints), stains, varnishes, pesticides, herbicides, poisons, gasoline and other fuels, solvents and strippers, aerosols, motor oil and filters, gas cylinders (BBQ pit size or smaller), fluorescent tubes, rechargeable batteries, alkaline batteries, antifreeze, brake and transmission fluid, pool chemicals and other acids and bases, car batteries, wood preservatives, driveway sealant, and items containing mercury (such as thermometers, thermostats, and mercuric salts).

Facility hours will vary based on time of year and demand for service. Appointments are by reservation and residents can schedule an appointment at their convenience.  Click here to make a reservation.

7. Are there costs to participate?
If you bring latex paint you will be charged the recycling fee of $.20 per pound.  For other HHW materials, the first 50 lbs of HHW will have no cost to the resident.  Any additional HHW materials over 50 lbs will have a cost to the resident of $1.00 per pound.

8. How is this program funded?
This program is funded in part through a grant from the St. Louis-Jefferson Solid Waste Management District and the Missouri Department of Natural Resources. Construction of the Saint Louis County sites and supplemental disposal for St. Louis County residents comes from the Saint Louis County voter approved landfill surcharge fees.

9. What method of payments do you accept?
The facility accepts cash and credit card (American Express, Discover, MasterCard and Visa).

10. What do I need to bring at the time of my appointment?
Please bring your printed voucher confirmation of the reservation and proof of address such as driver's license or utility bill. 

11. Do you accept materials not in their original container?
Yes, but please bring HHW in its original container(s), if possible.  If the original container is damaged, save as much of the label as possible to identify contents. 

12. If I bring old gas in a gas can, will the container be returned?
Yes.

13. What are guidelines for safe transport?

  • Tighten lids and ensure that all HHW containers are stored upright, preferably in a lined box to prevent and contain spills.
  • Ventilate your vehicle by keeping two windows open.
  • Drive directly to the permanent HHW facility after loading your HHW.

14. What can I expect when I arrive at the facility for my appointment?

  • Signs will direct you to the designated drop-off area. Please stay in your car and please do not smoke. 
  • The HHW contractor will take your printed confirmation voucher and verify your address.
  • The materials will be unloaded by the contractor and placed on a scale visible to you.
  • After confirming weights, you will be advised of any fees due.
  • If you have a fee to pay, you will be given a receipt.

15. What happens to my waste once I drop it off?
Up to 85% of the waste is recycled or recovered as waste to energy. The remainder is managed like regulated hazardous waste and in accordance with applicable regulations.

16. Will there be one-day collection events for St. Louis County residents?
The permanent program is replacing one-day collection events. Since 1998, the Saint Louis County Department of Health has held one-day collection events at an approximate cost of $7 million! In addition to offering a more convenient disposal option to residents, the permanent program will be more cost effective than the one day events.

17. Why do I pay for HHW over 50 pounds?
Proper management and disposal of HHW is expensive.  Funds used to subsidize the management fee for the first 50 pounds of HHW come from Saint Louis County landfill surcharge fees and Missouri Department of Natural Resources landfill tipping fees.  As landfills close and recycling increases, these funding sources are decreasing. By having residents share in the costs it will conserve funds and encourage responsible and conservative purchasing practices to reduce the amount of HHW created.

18. Why is latex paint not included in the first 50 pounds of subsidized disposal?
Latex paint is not considered a hazardous waste. The goal of the HHW program is to keep toxic materials out of the landfill. Limited HHW funds need to be conserved for disposal of materials that are hazardous.
Latex paint recycling is offered through the program as a service to residents who want an alternative to landfill disposal. The $.20 per pound fee encourages residents to utilize alternative options for latex paint, starting with purchasing only the amount needed for the job and sharing leftovers.  If completely hardened or dried out latex paint can be safely disposed of in the trash. Please contact your hauler for additional requirements. See Proper Paint Disposal.

19. Why are St. Louis City and Jefferson County residents limited to one drop-off per year?
Disposal funds for St. Louis City and Jefferson County are provided solely through a grant from the St. Louis-Jefferson Solid Waste Management District and the Missouri Department of Natural Resources. Officials from these jurisdictions made the decision to limit their residents to one drop-off per year to help preserve funding for as many households as possible. The year is a calendar year. A resident dropping off materials in October, would be able to make a reservation again in the following January.

Saint Louis County residents have voter approved landfill surcharge fees that supplement funding for HHW, permitting more than one reservation per year.

20. Can schools, small businesses and churches use this facility?
The program can only accept residential hazardous waste. Commercially generated waste is prohibited by law. This includes businesses, not-for-profit groups, schools, churches, farms, conditionally exempt small quantity generators (CESQG) and government agencies. Entities whose status is defined as a Missouri Department of Natural Resources Conditionally Exempt Small Quantity Generator have special options for disposal of hazardous waste and should reference http://dnr.mo.gov/pubs/pub128.pdf.
