UNSPSC 11191801: Manganese slag

A byproduct produced during processing of manganese ore

UNSPSC 11191801 Manganese slag, a Commodity code, represents materials recovery and recycling operations where state and local governments acquire collection, processing, and disposition services for metal and material waste streams. The recent solicitation activity under this code shows that state and local buyers are procuring metal recycling services, e-waste disposal and recycling, material processing equipment, and waste-to-energy facility operations—with pricing frequently tied to commodity market indices such as the American Metal Market (AMM) monthly averages or scrap yard spot pricing. Counties and regional authorities issue the majority of opportunities, with Ventura County, California; Sacramento County, California; Clayton County, Georgia; and DeKalb County, Georgia appearing as active recent buyers. The Solid Waste Authority of Palm Beach County and Sourcewell (a Minnesota cooperative purchasing vehicle serving multiple Participating Entities) also recently posted opportunities under related material processing and waste management scopes.

Geographic activity concentrates in California and Georgia, with scattered activity in Minnesota and Florida. Representative recent opportunities include Sacramento County's metals collection and recycling IFB (due June 9, 2026, covering 10,800 tons of mixed metals and unprocessed appliances), Ventura County's metal recycling RFB and e-waste recycling RFB (both due June 24, 2026, with compensation based on AMM index pricing), Clayton County, Georgia's e-waste disposal services ITB (due June 25, 2026), and DeKalb County, Georgia's three-year steel plates ITB (due July 23, 2026, with 20% local small business enterprise subcontractor participation requirement). Sourcewell issued an RFP for material processing and recycling equipment as a cooperative purchasing vehicle (due November 24, 2026), and the Solid Waste Authority of Palm Beach County posted a Request for Expressions of Interest for demolition, design, build, operation, and maintenance of a mass-burn waste-to-energy facility (due November 18, 2026). Most contracts run one to three years with optional renewals, and prevailing wage compliance is standard across California jurisdictions.
