About SUN METALON Inc.

For too long, metal recycling has been both financially and environmentally costly—up to 20% of all metal is lost during manufacturing. Because recycling that scrap is so expensive, much of it ends up in landfills. At Sun Metalon, we are changing that. Our zero-CO₂ technology transforms contaminated, low-value swarf into high-value metal—directly on-site. We’re not making new metal—we’re making metal new.
