Ingham County residents can drop off household hazardous waste for the last time in 2026 on Tuesday, Sept. 29, at 5303 S. Cedar St. in Lansing.

The Ingham County Health Department's free collection program, which opened May 5, wraps up with a final session from 2 p.m. to 6 p.m., WLNS reported. The facility sits behind the Human Services Building. Drop-offs will not be accepted before 2 p.m.

Residents should stay in their vehicles and let staff unload the materials.

The program accepts a wide range of items that can contaminate water sources or cause fires: pesticides, herbicides, antifreeze, brake and transmission fluids, oil-based paints, fluorescent bulbs, rechargeable batteries and aerosol products.

Small one-pound propane tanks, mercury-containing devices and sharps such as needles and EpiPens are also accepted. Sharps must be in puncture-resistant, sealable containers. Mercury devices must be double-sealed in plastic bags.

Residents bringing gasoline or fuel oil should be prepared to leave their containers behind.

Several common items are not accepted. Latex paint is non-hazardous and can be dried out with kitty litter or sawdust, then tossed in regular trash. Alkaline batteries, smoke detectors and drywall compound can also go in the trash. Car batteries, waste oil, explosives and ammunition are excluded. For ammunition, the health department's website directs residents to contact local police.

Prescription medications are not accepted at the hazardous waste site. The health department refers residents to a local police department or pharmacy through the Take-Back Meds program.

The collection is open only to Ingham County residents. Business waste is not accepted. The program may close for severe weather, including heavy rain, lightning, tornado watches or excessive heat. One session during the 2026 season, on Thursday, Sept. 3, was canceled due to lightning.

None of the hazardous waste collected goes to local landfills, according to the health department. A contracted waste hauler disposes of materials under federal hazardous waste regulations.

For intact fluorescent bulbs, the health department recommends transporting them between layers of cloth towels to prevent breakage. Broken bulbs can go in regular trash.

Residents with questions can call the Ingham County Health Department at (517) 887-4312. The 2027 season start date has not been announced.
