Alex Stege is a Vice President, Senior Project Advisor, and SCS Engineers’ National Expert on Landfill Gas Modeling. He leads SCS’s non-regulatory landfill gas (LFG) recovery modeling services, which have for decades supported developers and investors in LFG-to-energy and renewable natural gas (RNG) projects. Over nearly three decades, Mr. Stege has developed and updated the SCS LFG Recovery Model and led the team that applied it to prepare LFG recovery projections for methane utilization projects at hundreds of landfills in North America. The SCS LFG model uses a database of over 1,750 years of measured LFG flows and SCS assessments of collection system performance at 272 landfills to define LFG model input assumptions empirically. Mr. Stege frequently presents at conferences hosted by the Solid Waste Association of North America (SWANA), the Global Waste Management Symposium, and the International Solid Waste Association (ISWA).
