Each winter the landfill keeps its weekday hours but opens only every other Saturday, 8 to 11:30 a.m. In 2026 that ran from January 1 to April 1, with the open Saturdays listed on the county's page. If a holiday or winter storm closes the landfill, it opens the following Saturday morning instead.
Illinois keeps a long list of things out of its landfills: car batteries (since 1990), yard waste (since 1990), appliances that still have their Freon, mercury switches or PCB parts (since 1994), whole tires, and, since January 1, 2012, TVs, computers, monitors, printers and other electronics. That's why landfills turn them away and counties run separate programs for them.
