The Dingfeng Process: How We Recycle Scrap Spark Plugs

Ever wondered what happens to your old spark plugs after they’re replaced? At Dingfeng Precious Metals, we turn scrap into treasure through a meticulous recycling process. Our goal is to recover valuable platinum and iridium while minimizing environmental impact—here’s how we do it.
It starts with collection. We work with auto repair shops, scrapyards, and industrial clients to gather used spark plugs in bulk. Once they arrive at our facility, our team sorts them to ensure only intact platinum- or iridium-tipped plugs are processed. Damaged or copper-based plugs are set aside, as our focus is on precious metals.
Next, we extract the electrodes—the tiny tips where the magic happens. These contain platinum and iridium, which we recover using advanced separation techniques. Our methods are designed for efficiency, ensuring we reclaim as much metal as possible without excessive energy use or waste. The remaining steel and ceramic components are responsibly disposed of or repurposed, aligning with our commitment to sustainability.
What sets Dingfeng apart is our expertise and transparency. With years of experience in precious metal recycling, we’ve honed a process that maximizes value for our clients. Businesses benefit from fair pricing based on the recovered metals, while the environment gains from reduced mining demand. Whether you have a small batch or a truckload of scrap spark plugs, we’re equipped to handle it with care.
At Dingfeng Precious Metals, recycling isn’t just a service—it’s a mission. Join us in turning scrap spark plugs into a resource for the future. Contact us to schedule a pickup or get a quote today!
