Where it is
Other options they point to
For tires, the city suggests Walmart Automotive (512-310-9024), Discount Tire (512-341-8593) or NTB (512-238-9523). For needles and syringes, it points to TCEQ's guide to disposing of household syringes and to Sharps Inc. For medicines, use select pharmacies or Drug Take-Back Day. Williamson County residents can also use the county's twice-a-year collection days.
Good to know
Keep products in their original containers, sealed, and label anything unmarked. Don't mix products or put them in bags; set containers in boxes. Dried-out latex paint cans can go next to your trash cart with the lid off. Free reusable paint and cleaners at the Re-USE Building (you sign a waiver).
