Leaving waste unattended while we are closed is considered illegal dumping. These facilities are under 24 hour surveillance and you will be fined for the illegal dumping that is putting surrounding residents and workers in harms way.  

We do not have appropriate staff available everyday, so please respect our posted hours and days of service found here




Thank you for properly managing your household hazardous waste!


 We get life happens, and you may want to come earlier or later than your appointment time or on a day that works better for your schedule. That is why we welcome walk in’s during operating hours and fluctuating your appointment time with no advanced notice!

Did the previous owner of your house leave paint thinner and pool chemicals?  Are you helping a parent move to a condominium and you have jars of hobby paint purchased in the Reagan administration?  Whatever the reason, many of us have hazardous products that are too old to use.  They just need disposal.  So- how does St. Louis Household Hazardous Waste (HHWSTL) work?
