UNSPSC 11101701: Slag or ash

UNSPSC 11101701 Slag or ash (Commodity) covers waste and byproduct materials recovered from industrial processes, wastewater treatment, and construction demolition that state and local governments procure for road base, fill, embankment stabilization, and similar bulk civil works applications. Recent state and local solicitations under this code show purchasing activity centered on sewer infrastructure rehabilitation and pavement management projects where recycled or reclaimed materials support structural repair and roadway resurfacing work. The issuing bodies are typically county sanitation districts and county public works departments managing regional infrastructure systems.

Santa Clara County has posted two representative opportunities in 2026. County Sanitation District No. 2-3 issued ITB ITBRDAFY270088 (due September 17, 2026) for the Structural Defect Repair Project Phase 2, a sewer mainline rehabilitation program in unincorporated eastern foothills requiring removal and replacement of vitrified clay pipe with PVC and HDPE pipe, service connection fittings, and two sewer mainline extensions—work that may incorporate slag or ash as structural backfill or bedding material. Santa Clara County also issued ITB ITBRDAFY260694 (due May 21, 2026) for the Central Expressway Pavement Rehabilitation Project between Bowers Avenue and Scott Boulevard, encompassing partial depth recycling, hot mix asphalt overlay, pavement repairs, PCC curb and gutter installation, and related improvements over a 142 working day schedule. The code shows limited recent transparent activity; both Santa Clara County opportunities indicate materials procurement as a component of larger infrastructure contracts rather than standalone bulk material purchases, and neither explicitly names slag or ash in scope summary language, suggesting the code may reflect tagging conventions that do not directly map to current solicitation practice in this region.
