Dross Recycling Program


How valuable are solder scraps?

Stellar presents our SuperStars with a feel-good opportunity to dispose their dross in a safe and certified manner, while also potentially gaining supplemental savings. Win for the environment!

Environmental Benefits

Dross recycling reduces the need for raw material extraction, which often involves harmful mining practices. (See our Conflict Materials Policy.) By recycling dross, we minimize the environmental damage caused by mining activities, such as deforestation, soil erosion, and habitat destruction.

Energy Conservation

Recycling dross consumes less energy to melt down and repurpose metals compared to producing new materials from scratch. By conserving energy, we reduce greenhouse gas emissions and combat climate change.

Waste Reduction

Dross, if not recycled, often ends up in landfills, where it takes up space and can release harmful substances into the environment as it decomposes.

Stellar plan in action!

Stellar commits to sustainability and demonstrates our responsibility to our community to reduce, reuse, and recycle. We buy your dross, and in exchange, you get the best value back. Win-win for everyone!

What will be accepted for recycling?

Dross (pot skimming scraps): Stellar will provide customer-friendly and industry-complaint buckets. Included labels and shipping documents keep solder dross, scrap solder paste, and various other solder scrap materials from being cross contaminated in order to maximize returns. Silver and tin adds significant value.

  • Lead: Black Buckets

Waste: Accepted only along with dross pick-up.

  • Expired wires
  • Wipes (solder paste residue)
  • Many other metals and materials can be recycled--please inquire for your specific needs

E-Waste (electronics of no monetary value): Accepted only along with dross pick-up, and maximum poundage for pick-up.

  • Printed Circuit Board components (wasted, rejected, or unwanted)
  • Computers, Televisions, Monitors/Screens
  • Printers, Fax Machines, Copiers, Scanners

How will the items be recycled?

There is minimum dross poundage required to schedule a pick-up (any less may forfeit cash back... but you're still an environmental enthusiast and that's stellar in our book). There are no minimum waste or E-waste poundage required, and are a courtesy pick-up only with dross. Stellar operates with an ISO-certified and EPA-approved transportation company and facility for safe recycling.

When solder dross, scrap solder paste and various other solder scrap is received, the customer gets an acknowledgement of receipt, a settlement report, a Certificate of Recycling and payment for the received material. It takes up to 90 days for the process of buy back to be completed.
