THE LOCAL ANSWERBook a drop-off at hhwstl.com for the South site (291 E. Hoffmeister, Thursday–Friday) or North site (Florissant, Wednesday). Oil-based paint counts as hazardous waste: St. Louis County residents get the first 50 pounds free, then pay $1.70 a pound, while St. Louis City and Jefferson County residents are charged for every pound right now. Latex costs $0.50 a pound there for everyone, so drying it and putting it in the trash is usually cheaper.
St. Louis City and St. Louis County share one hazardous waste program, HHWSTL, with two drive-through sites: South near the Lemay treatment plant and North in Florissant. You must book online. Oil-based paint counts as hazardous waste. Latex paint costs 50 cents a pound to recycle for everyone, so drying it and throwing it out is usually cheaper. Jefferson County residents can use the same sites.
Book first; walk-ups aren’t the plan
Reserve a morning or afternoon window at hhwstl.com. You can’t book the same day. The South site (291 E. Hoffmeister) is open Thursday and Friday; the North site (4100 Seven Hills Dr., Florissant) is open Wednesday. Each also opens on listed Saturdays.
City and Jefferson County residents pay from the first pound
St. Louis County residents get the first 50 pounds of hazardous waste free, paid for by a county landfill fee. HHWSTL’s FAQ says the free 50 pounds for St. Louis City and Jefferson County residents came from a grant that has run out for now, so they pay full price. The booking page calls this “full pay mode”: you’re charged for every pound. HHWSTL says the grant will come back in the future, so check the price shown when you book.
Latex: dry it unless you want to pay
HHWSTL says latex isn’t hazardous and charges $0.50 a pound to recycle it. A full gallon can weighs up to about 10 pounds. If you bring it, it must still be liquid; they can’t use dried cans. Otherwise harden it and put it in the trash, and check with your hauler about any extra rules.
Big loads go to Eureka
Each visit is capped at 500 pounds. For more than 100 pounds, HHWSTL sends people to Earthbound Recycling, 25 Truitt Dr. in Eureka. It takes paint Monday–Saturday, 9–5, for 30 cents a pound, no appointment.
