NIGP 95812: Bio-Solids Management Services

NIGP 95812 Bio-Solids Management Services is an Item code covering the specialized treatment, processing, and disposal of biosolids—the organic solids separated from wastewater—including inoculants, grinding services, and related operational support for composting and waste-to-resource conversion. State and local governments soliciting under this code are acquiring proprietary microbial inoculants for biosolids decomposition, industrial grinding and processing services for contaminated yard waste and wood waste feedstock, and ongoing technical support to meet EPA and state environmental-protection regulatory requirements such as the Process to Further Reduce Pathogens standard. Hillsborough County, Florida and the City of Dallas have posted recent opportunities under the code. The issuing bodies include county waste and environmental departments and city sanitation services, typically managing regional biosolids-processing facilities that convert municipal waste streams into agricultural compost or disposal-ready material.

Florida and Texas show the most recent activity. Hillsborough County posted a sole-source procurement on February 27, 2026 (due March 6, 2026) for a proprietary inoculant from HQ Compost Holdings, LLC to support its Modified Static Aerobic Pile composting process, processing approximately 37,500 wet tons of biosolids annually over a five-year term valued at $515,625. The City of Dallas issued an Indefinite Quantity service agreement bid on February 26, 2026 (due March 27, 2026) for mobile grinding and processing of clean wood waste and contaminated yard waste at throughput rates of 30 and 20 tons per hour respectively, with a three-year estimated contract value of $3,200,000 and two one-year renewal options totaling $3,700,000; a pre-bid conference is scheduled for March 10, 2026. Both solicitations require performance against strict environmental compliance, production, and operational-reporting standards, and both impose firm pricing for their initial contract terms.
