7 Items Illegal to Throw Away in Wisconsin State

7 Items Illegal to Throw Away in Wisconsin State

by

Wisconsin has strict laws about what items can be thrown away in the trash. The state bans certain materials from landfills and incinerators to protect the environment, conserve resources, and reduce landfill waste. Whether you are a homeowner, business, or institution, it’s important to know which items are illegal to dispose of in regular trash and how to properly handle them.

Here are 7 key items you cannot throw away in Wisconsin and why these bans exist.

1. Electronics

Most electronics are illegal to throw in the trash in Wisconsin due to their toxic components and valuable recyclable materials. This includes:

  • Cell phones

  • Computers and laptops

  • Tablets

  • Monitors and TVs

  • Printers, scanners, and fax machines

  • Hard drives and flash drives

  • Any device that plugs into a computer

These items must be taken to designated e-waste recycling centers or drop-off locations to prevent hazardous substances from contaminating soil and water.

2. Vehicle-Related Items

Certain automotive materials are banned from disposal in landfills because they contain hazardous chemicals. These include:

  • Lead-acid vehicle batteries

  • Tires

  • Used motor oil and oil filters

  • Brake fluid, carburetor cleaner, transmission fluid, and degreasers

These items require special handling and can often be returned to retailers or hazardous waste collection sites for proper recycling or disposal.

3. Paints and Solvents

Latex, oil-based, and lead paints, along with solvents like lighter fluid and gasoline, cannot be thrown in the trash. These substances are flammable and toxic, posing risks to sanitation workers and the environment. Latex paint cans must be completely dried out before disposal, but oil-based paints and solvents should be taken to hazardous waste facilities.

4. Appliances

Major household appliances are banned from landfill disposal due to their size and potential environmental hazards (e.g., refrigerants). This includes:

  • Refrigerators and freezers

  • Air conditioners and dehumidifiers

  • Dishwashers, ovens, and stoves

  • Clothes washers and dryers

  • Water heaters and furnaces

Appliances should be recycled or disposed of at approved facilities that can safely handle refrigerants and metals.

5. Yard Waste

Grass clippings, leaves, brush, and other yard debris are banned from landfill disposal because they can be composted and reused. Many communities offer yard waste collection or composting programs. Leaving grass clippings on your lawn or using municipal composting services helps reduce landfill volume and supports sustainable practices.

6. Paper, Cardboard, and Containers

Wisconsin law bans recyclable paper products and containers from landfill disposal to conserve resources. These include:

  • Corrugated cardboard and containerboard (flattened)

  • Newspapers, magazines, and office paper

  • Aluminum, steel (tin), and bi-metal containers

  • Glass containers

  • Plastic containers #1 and #2 (milk jugs, soda bottles, detergent bottles)

These materials should be recycled through local programs or drop-off centers.

7. Hazardous Household Waste

Items classified as hazardous household waste must never be thrown in the trash. This category includes:

  • Pesticides, herbicides, and chemicals

  • Medical waste such as syringes and sharps

  • Mercury-containing items

  • Flares and empty hazardous material containers

These require special disposal at hazardous waste collection events or facilities to prevent environmental contamination and health risks.

Why Does Wisconsin Ban These Items?

The bans aim to:

  • Protect the environment by preventing toxic substances from polluting soil, air, and water

  • Conserve landfill space by diverting recyclable and compostable materials

  • Promote recycling and reuse to reduce demand for new raw materials

  • Ensure public health and safety by properly handling hazardous and flammable materials

Violating these disposal bans can result in fines and penalties, so proper disposal is essential.

How to Dispose of Banned Items Properly

  • Use local recycling programs and drop-off centers for recyclables and electronics

  • Return automotive products like batteries and tires to retailers or hazardous waste sites

  • Attend community hazardous waste collection events for paints, chemicals, and medical waste

  • Compost yard waste or use municipal yard waste services

  • Contact your local Department of Public Works or Wisconsin DNR for guidance on specific items

Conclusion

Wisconsin’s disposal bans cover many common household and automotive items that can harm the environment or waste valuable resources if landfilled. Knowing these 7 key categories helps residents and businesses comply with state law and contribute to a cleaner, safer Wisconsin. Always check with local authorities or the Wisconsin Department of Natural Resources for the latest rules and disposal options.
