How to Recycle Garbage Disposal: Safe Removal & Recycling Tips

Garbage disposals are made mostly of metal — steel, aluminum, and copper — which makes them ideal candidates for recycling.

Before tossing your disposal in the trash, consider local recycling centers, scrap metal buyers, or donation programs. Knowing how to recycle garbage disposal safely ensures you handle heavy metal parts properly, comply with local regulations, and give your old appliance a second life instead of letting it sit in a landfill.

Before You Recycle garbage disposal: Consider Donating

If your disposal still works and you’re replacing it with an upgrade, donate it. Habitat for Humanity ReStores, local thrift shops, and community reuse centers accept working appliances. A functioning disposal has value to someone on a tight budget.

How to Safely Remove Your Old Disposal

Follow these steps in order. Getting the sequence wrong creates a serious electrical hazard.

Step 1: Cut the power. Turn off the circuit breaker that feeds your disposal. If your unit is hardwired, confirm the circuit is dead with a voltage tester. If it’s plug-in, unplug it from the outlet under the sink. Never skip this step. Learn more in our garbage disposal dedicated circuit guide.

Step 2: Disconnect the drain. Loosen the slip-joint nut connecting the discharge tube to the P-trap. Have a bucket underneath to catch residual water.

Step 3: Disconnect the dishwasher hose (if connected). Loosen the hose clamp on the disposal’s dishwasher inlet and pull the hose free.

Step 4: Disconnect the electrical wiring. Remove the cover plate on the bottom of the unit. Disconnect the wire nuts joining the disposal wires to the supply wires. Remove the ground wire from the green screw.

Step 5: Remove the unit. Support the disposal from below, then rotate the lower mounting ring counterclockwise until it releases from the mounting assembly. The unit will drop into your hands — they’re heavy, so be ready.

Where to Recycle Your Old Disposal

Scrap Metal Yard

Most scrap yards accept garbage disposals as mixed metal. You may receive a small payment based on weight. Call ahead to confirm they accept appliances with attached wiring.

Municipal Recycling or E-Waste Center

Many cities and counties operate drop-off facilities that accept small appliances. Check your local waste management website for locations and accepted items.

Retailer Haul-Away

Some retailers and installers will haul away your old unit when they deliver a new one. Ask about this option when purchasing your next garbage disposal.

Curbside Bulk Pickup

Many municipalities offer scheduled bulk item pickup for items that don’t fit in standard bins. Place your old disposal at the curb on the designated day, and tag it if required by your local program.

What About Throwing It Away?

You can put a garbage disposal in the regular trash in most areas, but it’s wasteful. The metals inside are fully recoverable, and recycling keeps heavy items out of landfills. Recycling takes minimal effort and is the better choice.

Conclusion

Recycling a garbage disposal is straightforward. Cut the power, disconnect the plumbing and wiring, remove the unit, and drop it off at any scrap yard or recycling center. If it still works, consider donating it instead. Either way, keeping metal out of the landfill is a simple win. Happy recycling of your disposal!
