UNSPSC 73101801: Biomass production services

UNSPSC 73101801 Biomass production services (Commodity) describes chemical additives and treatment agents for water and wastewater processing—a narrower scope than the code name suggests. State and local governments procure dewatering and thickening polymers for sludge treatment, antifoam additives for leachate evaporators, filter media for municipal water treatment, water treatment chemicals including fluorosilicic acid and dense soda ash, and related process chemicals on annual or multi-year service contracts. The issuing bodies include county departments of water resources and solid waste management, municipal water and wastewater utilities, and municipal procurement offices acting on behalf of public works and operations departments. Contract structures typically feature firm pricing for an initial one- to four-year term, optional renewal periods conditioned on satisfactory performance and budget authorization, and competitive sealed bids or RFPs evaluated on total cost per unit of service, vendor reputation, quality, and compliance with small business goals where applicable.

Recent solicitations show activity concentrated in the Southeast and Pacific Northwest. Gwinnett County, Georgia (Department of Water Resources) issued a competitive sealed bid on July 1, 2026 for solids dewatering and thickening polymer with a July 30, 2026 response date, awarding a four-year contract commencing October 19, 2026 with four optional one-year renewals based on lowest cost per dry ton of sludge and polymer effectiveness. The City of Salem, Oregon solicited dense soda ash in April 2026 (due May 13, 2026) for bulk and sacked delivery to its water treatment plant under a one-year contract with four optional renewals, and fluorosilicic acid (due April 1, 2026) for drinking water fluoridation on similar terms.
