How to Recycle Spark Plugs & Engine Components
Spark plugs, ignition coils, sensors, and small engine hardware. Premium plugs use platinum or iridium electrodes; coils and modules add copper windings and circuit boards.
Quick answer
Spark plugs and small engine parts are scrap metal. Platinum and iridium plugs are worth sorting from copper plugs when a buyer wants them. Degrease when you can, then take them to a scrap yard, precious-metal buyer, or parts-store core program. Ceramics and coils may route through e-waste if the yard asks.
- Recyclable
- Yes
- Typical value
- Copper plugs: pennies in mixed scrap. Platinum/iridium: ask a precious-metal buyer (payouts vary and are often small). Coils/modules: core price or small e-waste payout.
- 1Remove parts with a cool engine
- 2Keep platinum/iridium plugs in a separate bag from copper plugs
- 3Wipe heavy grease so yards can grade the metal
- 4Pull plastic connectors off coils if an e-waste site wants boards bare
- 5Check core lists before scrapping reman-eligible sensors or coils
- Scrap metal dealers
- Precious-metal buyers that take spark plugs
- E-waste recyclers (coils, modules, sensors)
- Auto parts stores with ignition core returns
Precious-metal buyers sometimes pay per plug for platinum/iridium tips; amounts vary and are often small. Standard copper plugs usually ride with mixed steel/nonferrous scrap. Ignition coils and electronic sensors fit e-waste or auto-electronics recycling better than bottle-bin metal.
Recovered platinum-group metals from plug tips return to industrial use. Copper from coils and steel shells recycle with other nonferrous and ferrous scrap.
Accepted
- Copper, platinum, and iridium spark plugs
- Glow plugs from diesels (ask the buyer)
- Ignition coils and coil packs
- Cam/crank sensors and similar small electronics
- Steel brackets and fasteners from the job
Not Accepted
- Parts still dripping oil into a clean scrap bin
- Live airbag or pyrotechnic devices
- Full catalytic converters (separate material)
- Household trash for platinum plugs you could sell
Estimated value: Copper plugs: pennies in mixed scrap. Platinum/iridium: ask a precious-metal buyer (payouts vary and are often small). Coils/modules: core price or small e-waste payout.
Are platinum plugs worth sorting?
Yes if you have a buyer. Premium electrodes hold more platinum-group metal than copper plugs. Ask before assuming a fixed dollar-per-plug price.
Can I recycle ignition coils?
Copper windings and electronics go to e-waste or a scrap dealer that takes coils. Check core credit first.
Do yards want the ceramic insulator?
They buy the metal. Ceramics may be tolerated in a plug load or asked to be broken off. Follow the yard's rule.
What about oxygen sensors?
Some contain platinum-group metals and sell to specialty buyers; others go with e-waste. Ask before tossing.
Should oily plugs be cleaned?
Wipe them. Soaking solvent that becomes hazardous waste is usually not worth it for a few plugs.
