UNSPSC 26131608: Flare or vent stacks

UNSPSC 26131608 Flare or vent stacks is a Commodity code that encompasses the design, construction, installation, and maintenance of enclosed flare systems and vent infrastructure used to combust landfill gas and other industrial emissions at waste-management and utility facilities. State and local governments procure flare and vent stack services primarily through competitive sealed bids issued by environmental agencies, solid waste authorities, water districts, and municipal departments managing landfill operations or distributed energy resources. The scope spans new flare system construction, demolition of existing flares, and long-term maintenance contracts for stack equipment and combustion systems. Work is often tied to air-quality compliance, waste-to-energy facility operations, or environmental remediation initiatives.

Recent activity centers on a handful of state and local issuing bodies in the Mid-Atlantic and Southeast regions. Maryland Environmental Service posted a competitive sealed bid (1274025) in June 2026 for construction of a new enclosed flare system to combust landfill gas and demolition of existing flares at the Brown Station Road Sanitary Landfill in Upper Marlboro, with bids due July 16, 2026, under a 20% Minority Business Enterprise participation goal. The Solid Waste Authority of Palm Beach County issued a Request for Expressions of Interest (RFEI 27-501) in September 2026 for demolition, design, build, operate, and maintain services for a new mass-burn waste-to-energy facility processing up to 2,550 tons per day, with letters of interest due November 18, 2026, and an industry day planned for December 10, 2026. Beyond the flare-specific bid and the waste-to-energy RFEI—which includes flare and stack components within a larger EPC scope—the code shows minimal documented recent activity among state and local procurement bodies.
