Recycled brass can come from industrial scrap, hardware, or salvaged brass objects. Brass is generally a copper-zinc alloy; recycling it preserves material quality while reducing energy and extraction impacts. Sourcing is global and depends on scrap collection systems. Challenges include verifying provenance claims (e.g., “from bombshells”), worker safety in informal scrap sectors, and transparency in refining. Certifications are less standardized than textiles, but some suppliers provide recycled content documentation; broader facility certifications may apply depending on the producer. Recycled brass is used in jewelry, hardware, and decorative details.
