Disposal of Microwaves

Disposal of certain kitchen appliances such as microwave ovens is not as simple as dumping them in the trash. Circuit boards in some consumer electronic devices are considered hazardous materials and need to be disposed of properly in accordance with laws and regulations.
  1. Options

    • If you are updating an existing microwave that still works, consider donating it to a charity or foundation that can distribute items to needy people. Check with family members or friends to see if anyone is interested in a used microwave.

    Recycle or Refurbish

    • Check with your local recycling center. Sometimes it will take old household appliances such as a microwave, fix them and sell as refurbished at a discounted price. Another option is to consult with appliance repair shops in your area to see if the microwave can be used for parts.

    Oil-Filled Capacitors

    • Running or oil-filled capacitors are found in dehumidifiers, fluorescent light ballasts, air conditioners and microwave ovens. Federal regulations govern against the crushing, shreddling or bailing of any polychlorinated biphenyls (PCB) small capacitors. These types of appliances contain materials with the potential to contaminate waste piles, surface waters and soils. Removal of PCB capacitors is required prior to processing the appliances. In the state of California a microwave oven is considered hazardous electronic waste. Check with your local and regional landfill officials to ascertain the appropriate rules and regulations in regard to disposal.

    Microwaves

    • The running capacitor in a microwave is generally wired to the transformer behind the control panel. Electrical capacitors will store charges for several days after the last usage of the appliance, so take precautions when removing it. Or, wait for a few weeks after the microwave quits before attempting to remove the capacitor.
