Let us begin by separating these spark plugs from other metals you collect for recycling. Keep them in a different container until you are ready to pack and ship. When sending a bulk shipment, we like to accept them in 55-gallon drums. Please avoid using gaylords or large plastic boxes. You can strap three-four 55-gallon drums to a sturdy pallet or skid. This would represent a minimum 3,000-4,000 lb. bulk shipment. We also accept tailer load quantities. Remember to please keep out all trash, no copper plugs, no partial plugs, no scrap metal and oil.

All Iridium and Platinum plugs are accepted. We do not accept copper plugs – no value. Only whole plugs – no partials. Do not include copper plugs, trash, scrap metals – clean, no oil.

Most of the bulk weight of spark plugs consist of iron. Small amounts of nickel are used on the electrodes themselves. Many contain a copper core through the center of these electrodes along with very small quantities of Iridium and Platinum welded to the tip. The insulator is made from a ceramic based upon aluminum oxide.
