Illinois keeps a number of common items out of landfills. Televisions, computers and many other electronics cannot be landfilled, and batteries, tires and landscape waste each have their own route.
Hazardous material stays out of a container in every case: paint, solvents, fuel, used oil, pesticides, asbestos and anything holding refrigerant.
The City's own curbside service tells you what a container is for. Its curbside crews leave out earth, sod, rocks, concrete and material from remodeling or building a home. They take only small amounts that one person can lift. So the moment a job produces more than an armful of construction debris, it needs a container rather than the curb.
On a covered project the sorting rules matter as much as the banned list. The City counts soil and rock as construction debris, along with masonry, wood, drywall, fixtures, insulation, shingles, old asphalt, glass, wiring and cardboard. So dug-out soil and land clearing material count toward the diversion math here. Some nearby towns leave them out. It is worth knowing before the excavator starts.
Compost piles have their own limits too, with meat, bones, fat, dairy and pet waste kept out.
When an item has you unsure, ask your account manager before it goes in the container.
