UNSPSC 10171504: Compost

UNSPSC 10171504 Compost (Commodity) covers the supply, application, and refurbishment of compost materials used for odor control, erosion stabilization, landscaping, and biosolids land application by state and local environmental, waste management, parks, and transportation agencies. State and local governments buy finished compost products (typically Type Y compost meeting state environmental specifications), compost-based mulch for odor management at wastewater treatment facilities, and related land application and landscaping services. Recent solicitations show municipalities and counties acquiring compost primarily for three distinct uses: odor control at wastewater utility facilities (refurbishment and replacement of mulch beds at vacuum stations), landscaping mulch supply and installation for municipal parks and administrative facilities, and large-scale biosolids land application services where Class B biosolids are spread on agricultural land. Issuing bodies include county environmental and waste management departments (Sarasota County, Hillsborough County, Clackamas County Water Environment Services), municipal recreation and parks divisions (City of Norwalk, Town of Palm Beach, Sacramento County Department of Waste Management), and state transportation agencies (California Department of Transportation procuring through its districts).

Recent activity spans Florida, California, Connecticut, Oregon, South Carolina, and Colorado. Representative solicitations include Sarasota County's IFB 262888RM (posted July 6, 2026, due August 7, 2026) for five-year odor control mulch bed refurbishment and replacement at nine public utility vacuum stations requiring FDOT Type Y compost material and hydrogen sulfide atmospheric testing; Clackamas County Water Environment Services RFP #2026-12 (posted February 25, 2026, due March 25, 2026) for land application of Class B biosolids to agricultural sites across Oregon at approximately 7,000 wet tons annually; Sacramento County's RFB #2026-RFB-0049 (posted May 14, 2026, due June 11, 2026) for hydroseeding and erosion control using compost mix on landfill slopes; and the City of Norwalk's IFB 4491 (posted January 27, 2026, due February 11, 2026) for annual supply and delivery of decorative pine bark mulch and landscape materials. Procurement activity is active and geographically distributed, with recurring opportunities tied to fiscal-year landscape maintenance cycles and multi-year wastewater and landfill management contracts.
