NIGP 54583: Shredder, Aerator, and Composter for Sludge

NIGP 54583 Shredder, Aerator, and Composter for Sludge, an Item code, covers equipment used by state and local governments to process and manage wastewater treatment sludge and biosolids through mechanical shredding, aeration, and composting operations. The recent solicitation activity under this code remains limited; the single opportunity in the dataset reflects a cooperative purchasing vehicle rather than direct procurement of sludge-processing equipment. Sourcewell, a Minnesota local government unit and service cooperative, posted RFP #061626 on May 12, 2026 with a June 16, 2026 response deadline to establish contracting solutions for law enforcement equipment available to thousands of governmental agencies, public entities, school districts, and other organizations across the United States and Canada, though this broad-based cooperative vehicle does not appear narrowly targeted at sludge-processing commodity acquisition.

The geographic scope of recent activity spans multiple states and jurisdictions, with the Sourcewell solicitation advertising participation from Washington state counties (Franklin, Grant, Grays Harbor, Chelan, and Yakima) and numerous other public entities nationwide, reflecting the cooperative's multi-jurisdictional reach. Given the single opportunity in the recent dataset and its focus on law enforcement equipment rather than sludge-management commodities, procurement activity under NIGP 54583 for shredding, aeration, and composting equipment does not appear to be generating regular or concentrated solicitation volume at this time. Vendors pursuing this code should monitor state environmental agencies, wastewater authorities, and treatment facility managers directly rather than relying on recent broad cooperative postings to identify active demand signals for sludge-processing equipment.
