Wisconsin bans more from its landfills than most states do, and the ban applies in homes and on job sites alike. The Department of Natural Resources keeps out electronics, major appliances, lead acid batteries, waste oil, used oil filters, waste tires, and yard waste.
The list also covers everyday recyclables: corrugated cardboard, glass containers, newspaper, magazines, office paper, aluminum and steel cans, and plastic containers marked one and two. Cardboard is the one that trips up renovation jobs, since a kitchen install can produce a mountain of it. Flatten it and set it aside for recycling instead.
Hazardous waste, liquids, paint, solvents, fuel, and asbestos stay out of a standard container, and the city will not take medical, hazardous, or toxic waste in its own collection either.
Most of the rest is fine. Wood, drywall, plaster, lath, shingles, flooring, cabinets, and furniture all load normally. When something falls in a grey area, ask your account manager before it goes in.
