UNSPSC 73101506: Research and development refining services

Research and Development refining general bitumen, residues, syngas. Petroleum refineries change crude oil into petroleum products for use as fuels for transportation, heating, paving roads, and generating electricity and as feedstocks for making chemicals. Refining breaks crude oil down into its various components, which are then selectively reconfigured into new products.

UNSPSC 73101506 Research and development refining services is a Commodity code that state and local governments use to procure landfill gas collection system design, installation, and optimization work—specifically the engineering, surveying, well drilling, piping infrastructure, and equipment necessary to extract and process gas from solid waste facilities. The work encompasses site-specific assessment of gas well locations, installation of extraction wells with collection piping in multiple diameters, condensate handling, monitoring systems, and integration with existing leachate infrastructure, along with performance specifications for gas utilization rates and system reliability. Solid waste authorities are the primary issuing bodies under this code, supported by municipal water and wastewater districts when digester gas projects at treatment facilities are involved. The code also captures long-term design-build-finance-operate-maintain (DBFOOM) arrangements in which private entities design and operate gas-to-energy conversion facilities, recovering capital and operating costs through the sale of renewable natural gas or other energy products.

Recent activity concentrates in California and Georgia. The Dalton-Whitfield Solid Waste Authority issued an ITB on April 17, 2026, for landfill gas collection and control system expansion at its Old Dixie Highway Municipal Solid Waste Landfill in Dalton, Georgia, with bids due May 21, 2026, requiring Georgia-licensed general contractors with a minimum five years' landfill gas system experience and five completed similar projects within the past five years; substantial completion is mandated 120 calendar days after Notice to Proceed with liquidated damages at $2,000–$5,000 per day. The Eastern Municipal Water District in Riverside County, California, posted an RFP on February 24, 2026, for a long-term DBFOOM Digester Gas Utilization Project across three Regional Water Reclamation Facilities (Perris Valley, Temecula Valley, and San Jacinto Valley) to convert digester gas into renewable natural gas or marketable energy products at a minimum 90 percent utilization rate; proposals were due April 13, 2026, and the District requires proposers to demonstrate five years of direct DBFOOM digester gas experience, post bonds totaling $24 million, and maintain comprehensive insurance. The code shows limited recent activity—only two substantially relevant state and local opportunities in the dataset, with the remaining posted items unrelated to gas collection, refining, or utilization work.
