Why Recycle Your Old Garbage Disposal?

Garbage disposals are mostly metal, which means they are largely recyclable. Simply throwing the unit in the trash would waste those valuable materials. By recycling, the metal can be reclaimed and used to make new products, conserving resources and energy. Recycling scrap metal uses far less energy than mining and refining new metal a big win for the environment.
Another reason to recycle is that many states and cities have regulations about disposing of appliances and electronic waste. A garbage disposal may not look like a typical electronic gadget, but it does have electrical components (wires, motor, etc.). In many places, anything with a power cord is considered electronic waste (e-waste) and should not go in regular garbage. Some jurisdictions even ban appliances from landfills entirely or require special recycling check your local laws, but recycling is often the easiest way to comply.
There’s also an economic aspect: Scrap metal yards will take the metal parts, and some might even pay you a few dollars for the copper and steel inside your old disposal. It won’t be a windfall, but it’s better than paying to dump it. In short, recycling your old garbage disposal keeps heavy metal out of the landfill, conserves natural resources, and might put a couple bucks in your pocket or at least save you a disposal fee.
Safety First: Removing the Disposal from Your Sink
Before you can recycle your old garbage disposal, you need to safely detach it from your sink. If you haven’t removed a disposal unit before, don’t worry it’s a straightforward DIY task as long as you take it step by step and put safety first. Here’s how to get that old unit out without any disasters:
- Cut the Power: Unplug the disposal or turn off the circuit breaker controlling it. This is critical you don’t want any electricity flowing to the unit while you work. Double check that the switch is off or the unit is unplugged under the sink. If your disposal is hardwired (directly connected) rather than plug in, turn off the corresponding breaker at your electrical panel to be safe.
- Disconnect the Pipes: Place a bucket or towel under the disposal to catch any water. Using a screwdriver or pliers, loosen the clamp holding the dishwasher drain hose (if a dishwasher is connected) and remove the hose from the disposal’s side inlet. Next, use a wrench to loosen the coupling on the drain pipe. Once loosened, wiggle the drain pipe out of the disposal unit. Some water will likely drip out that’s what the bucket is for!
- Unlock the Disposal from the Mount: Most garbage disposals are attached to the sink’s mounting bracket with a simple twist lock mechanism. While supporting the unit with one hand (they can be heavy!), use a wrench or the disposal’s provided hex wrench to turn the mounting collar counterclockwise. Carefully lower the unit down and out from under the sink. Pro tip: it may help to have a second person hold the unit from below as you twist it free, especially for larger/heavier models.
- Disconnect the Wiring: If your disposal was plug in, you’re basically done. If it was hardwired, turn off the power, remove the cover plate, and disconnect the wiring. Use wire nuts to safely cap off any exposed wires under the sink.
With these steps, your old garbage disposal is now completely free from the sink and ready to deal with. Take a moment to wipe up any spills under the sink and maybe stuff a rag into the open drain line to block odors.
Consider Reuse or Donation Before Recycling
Before you jump to recycling, ask yourself: Could someone else use this old disposal? If the unit is still functional, there might be an opportunity to give it a second life. Here are a few reuse options to consider:
- Donate to a Reuse Center or Charity: Some nonprofit home improvement thrift stores accept working appliances and fixtures. A garbage disposal unit that runs and isn’t too old could be donated and then sold cheaply to someone who needs it.
- Sell or Give it Away Online: List the disposal on a site like Craigslist, Facebook Marketplace, or Freecycle. Be honest about the condition, and you might find someone interested in using it or salvaging it for parts.
- Repurpose It: Some DIYers have repurposed old disposal units for uses like compost grinders or other mechanical projects. These ideas require technical skills and safety precautions.
If your old unit is leaking, burnt-out, or severely rusted, reuse probably isn’t viable recycling is the way to go. But if it has some life left, someone else might benefit from it.
Recycling Options for an Old Garbage Disposal
If the old garbage disposal is not getting reused, it’s time to recycle it. The good news is there are several convenient ways to recycle a garbage disposal unit in the U.S. You’ll want to choose the option that fits your situation best. Below we break down the main recycling routes and how to navigate them:
- Drop Off at a Local Recycling Center or E-Waste Facility: Many cities have designated drop off locations for scrap metal or small appliances. Check your municipal website or waste management service for details.
- Take It to a Scrap Metal Yard: Most scrap yards will accept the unit and possibly pay a small amount based on the metal content. It won’t be much, but it ensures the disposal is properly recycled.
- Curbside Bulk Pickup or Appliance Recycling Programs: Some towns offer scheduled pickups for large items. You may need to request service and confirm it will be recycled.
- Retailer Haul Away Services: When replacing your garbage disposal, some retailers or contractors will haul away the old unit. Be sure to ask if they recycle it properly.
- Mail In Recycling Programs (Less Common): Some companies offer mail in recycling, though this may not be practical for heavier items like a garbage disposal.
Avoid These Disposal Mistakes
Now that we’ve covered the right ways, let’s be clear on what not to do with an old garbage disposal:
- Don’t throw it in the regular trash. Most cities don’t allow heavy appliances in household garbage, and they could be fined if found in landfill.
- Don’t toss it in your curbside recycling bin. These bins are not equipped to handle large, mixed material appliances.
- Don’t dump it illegally. Leaving it on the street or in an alley is not only irresponsible, it’s illegal in many areas.
- No need to take it apart. You can hand over the whole unit; recyclers will process it properly.
