Most construction and household debris is accepted. The limits come from Michigan's landfill rules and from the City's own ordinance.
Michigan keeps a defined list of materials out of landfills: asbestos, beverage containers subject to deposit, yard clippings other than diseased or invasive material, empty drums unless crushed or filled, hazardous waste, bulk liquids unless solidified, lead acid batteries, low-level radioactive waste, medical waste, waste containing PCBs, scrap tires, septage and used oil. Several of those need their own route rather than a container.
Garden City adds its own exclusion for anything set out for collection, naming poisons, dead animals, ammunition, explosives, concrete and dirt among the materials that may not go in a collection receptacle. Concrete and soil are exactly the materials that belong in a dedicated container instead.
The ordinance also treats a long list of heavy and oversized items as material the City's own system will not process, including ashes, cinders, sand, earth, metal furniture, pipe, structural steel, automobile parts, and lumber, scrap wood, cartons and crates longer than three feet. Again, that is a container job.
Hazardous waste, liquids, paint, solvents and fuel stay out of any standard container, and asbestos needs licensed abatement before demolition. If an item sits on the line, ask your account manager before it goes in.
