UNSPSC 71131104: Matrix organic inhibition services

Services using organic clay acid for matrix inhibition.

UNSPSC 71131104 Matrix organic inhibition services is a Commodity code that in practice encompasses landfill gas collection and control system infrastructure, digester gas utilization projects, and related organic waste-to-energy conversion work at municipal solid waste and wastewater treatment facilities. State and local governments soliciting under this code include solid waste authorities, municipal utilities, water reclamation districts, and city governments managing landfill operations and biosolids treatment. The work involves designing and installing gas extraction wells, collection piping, condensate handling systems, monitoring equipment, and related appurtenances, as well as longer-term design-build-finance-operate agreements to convert biogas into renewable natural gas or other energy products. Contractors must typically hold state-level licensing (general contractor credentials in jurisdictions like Georgia), demonstrate five or more years of directly relevant experience on similar projects, and perform substantial labor on-site; larger opportunities may require bonding and performance guarantees in the millions of dollars.

Recent activity clusters in Georgia and California, with the Dalton-Whitfield Solid Waste Authority in Georgia posting an ITB on April 17, 2026 (due May 21, 2026) for landfill gas collection and control system expansion at Old Dixie Highway Municipal Solid Waste Landfill—a construction and installation project with mandatory pre-proposal conference scheduled for May 1, 2026, requiring Georgia-licensed general contractors with five years of relevant experience and at least five completed similar projects—and the Eastern Municipal Water District in Riverside County, California posting an RFP on February 24, 2026 (due April 14, 2026) for a long-term Design-Build-Finance-Own-Operate-Maintain agreement to convert digester gas at three Regional Water Reclamation Facilities into renewable natural gas or energy products, with mandatory pre-proposal meeting March 9, 2026 and site tours March 18–19, 2026. The code shows limited but substantive recent activity; one opportunity in the block (City of College Park City Manager Executive Search Services) is unrelated to the code's scope and reflects a tagging mismatch rather than relevant procurement under this UNSPSC category.
