NIGP 54583: Shredder, Aerator, and Composter for Sludge

NIGP 54583 Shredder, Aerator, and Composter for Sludge is an Item code that encompasses wastewater and solid waste treatment equipment used by municipalities and county governments to manage biosolids, sludge dewatering, and organic waste diversion. State and local governments procure belt filter presses, centrifuge dewatering units, portable aeration equipment, and food waste collection services under this code. The issuing bodies are predominantly county governments (Collier County and Hillsborough County, Florida; Orange County, Florida) and municipalities (City of Pembroke Pines, Florida), with cooperative purchasing vehicles also active in the space—Sourcewell, a Minnesota local government unit, recently issued a cooperative RFP for law enforcement equipment that encompasses sludge and waste management solutions available to participating entities across the United States and Canada.

Recent solicitations show activity concentrated in Florida, with Hillsborough County issuing ITB 26-00167 on March 13, 2026 for centrifuge mobile sludge dewatering unit rentals across three equipment size categories (Small, Medium, Large) with an estimated contract value of $6,623,000 over five years and a bid deadline of April 2, 2026.

The City of Pembroke Pines solicited portable lift station aeration equipment or agitators with a proposal deadline of February 3, 2025. Orange County's Office of Sustainability & Resilience and Solid Waste Division jointly posted a residential food waste collection pilot project on March 27, 2026 with an Industry Day meeting and the same submission deadline, seeking operational setup and management of curbside food waste collection services.
