But do i have to make an appointment? The short answer is no, however, making an appointment assures we have the appropriate staff ready to help you! 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 and fluctuating your appointment time with no advanced notice! 

* Leaving waste unattended while we are closed is considered illegal dumping, so please respect our posted hours and days of service found here. *

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?
