Kent County publishes an unacceptable-waste list for its landfill and transfer station, and it is more specific than most. Barred outright are explosives of any kind, liquid wastes including gasoline, kerosene, hydraulic and waste oil, turpentine, solvents, liquid paint, insecticides and alcohol, asbestos, pathological and biological waste, sharps and needles, radioactive material, firearms, hazardous waste, and PCBs.
Two entries on that list catch people out. Whole tires are not accepted, though cut tires are. And white goods are barred from the landfill, so refrigerators, ranges, washers, and dryers have to go through the county's appliance route instead, with a charge per item where refrigerant is involved.
Yard waste is also unacceptable at the landfill, and Michigan deposit beverage containers are too. Bulk liquids have to be solidified and separately approved before they can be landfilled at all.
Kentwood adds its own line: no one may transport or dump refuse in a way that litters or damages any stream, creek, ditch, drain, culvert, or gutter. If you have an item that does not clearly fit any of these categories, ask your account manager before it goes in the container.
